Cooperation between China and the United States, the world’s two largest emitters of carbon dioxide, to limit emissions and pursue alternative energy paths has become a major global political challenge. NGOs, academic organizations, and policy think-tanks are involved in breaking through current barriers to cooperation.
Cooperation between the United States and China to reduce climate change (or global warming) is widely seen as one of the most pressing issues for the worldwide community. China’s energy consumption and carbon dioxide (CO2) emissions could grow more than fourfold in the next twenty years, thus catching up with and overtaking large industrialized nations (with the exception of the United States and Canada) in per capita emissions. Or, China could implement advanced energy technologies and policies to cut energy-demand growth, in which case itscarbon dioxide emissions might only double. The first case would impact the global environment very seriously; the second case is more tolerable. If the latter is accompanied by significant reductions of greenhouse gas emissions in industrialized countries and the aggressive development of low-carbon energy technology, the world could be on the way to cutting emissions significantly by 2050.
Strategic mistrust between China and the United States, however, has interfered with a binding global agreement on energy caps. The Chinese believe that a commitment to reducing carbon dioxide emissions could stifle their development; the U.S. speculates that, because of its large trade deficit with China, any adoption of a carbon dioxide cap without a comparable commitment by China could drive the two nations’ trade balance out of control.
A solution to the problem of greenhouse gas emissions depends critically on both countries. China and the United States account for nearly 40 percent of current global energy-related carbon dioxide emissions; they also have the greatest potential to reduce emissions growth. The participation of both nations is essential in the effort to establish a global regime to contain these emissions.
Background History
Fossil fuels—coal, oil, and natural gas—provide most of the world’s commercial energy. When they are burned, carbon dioxide is released; it and other greenhouse gases keep solar radiation (or heat) trapped on Earth. This is known as the “greenhouse effect.” According to the United Nations Intergovernmental Panel on Climate Change, the mean global temperature increased approximately 0.6oC from 1890 to 1990, and they predict a 1.1ºC–6.4ºC rise during the twenty-first century. This increase in surface temperatures on Earth can have catastrophic results, affecting weather, global water levels, and plant and animal life, among other issues. Energy-related carbon dioxide emissions make up approximately 80 percent of the greenhouse gases in the atmosphere, so their containment is a global issue.
While there is disagreement about solutions to climate change, there are some facts that are generally accepted regarding the historical, current, and anticipated future situation of China and the United States and greenhouse gas emissions.
The first mutually accepted fact is that the United States is responsible for 28 percent of total cumulative emissions of carbon dioxide from energy consumption, while China is responsible for 8.5 percent. Because of carbon dioxide’s long “residence time” in the atmosphere (more than 100 years), the contributions from many years ago affect the global greenhouse as much as today’s emissions. Therefore, the most important measure of energy-use contributions to greenhouse gases in the atmosphere is the cumulative emissions of carbon dioxide.
A country’s energy useconventionally is presented in terms of per capita emissions, in the same way that gross domestic product (GDP) per capita, not GDP alone, is a measure of the economic well-being of a country. (GDP is the total market value of all of a country’s goods and services produced in a given year minus the net income earned abroad.)
In describing contributions of a country, it is useful to present this in terms of per capita emissions, in the same way that GDP/capita, not GDP, is a measure of the economic well-being of a country. That is, over the entire period during which we can estimate carbon emissions due to human activity (roughly since 1850), China’s cumulative per capita emissions of energy-related CO2 are less than 8 percent of those of the United States.
This is generally seen as a remarkable achievement, as virtually all countries undergoing very rapid economic development—China had 9–10 percent annual GDP growth over those two decades—experience energy growth that is faster than GDP growth. China’s reduction in energy demand growth was the consequence of explicit policies carried out domestically. If energy had grown just at the rate of GDP, China’s emissions of CO2 would be more than twice as great as today’s emissions.
Notwithstanding these reductions in growth of CO2 emissions, U.S. CO2 emissions per capita are 2.5 times greater than those of the European Union countries and 2.1 times those of Japan. The European Union and Japan are not far behind the United States in GDP/capita. But these nations have much less land per capita and have much higher population densities. High population density reduces travel demand and results in smaller per capita emissions.
For industrialized countries, emissions are likely to decline over time in proportion to GDP growth because many activities and products have saturated their markets: For example, not many people are purchasing their first car, and virtually all homes have refrigerators and most are not seeking to have a second. This is confirmed by the fact that from 1975 to the present, the United States reduced the growth of its energy-related carbon dioxide emissions more than any other large industrialized country in the world. GDP per capita grew almost 200 percent while energy consumption (and carbon dioxide emissions) per capita remained constant.But it is useful to use a baseline that has carbon dioxide emissions growing at the rate of growth of GDP when making comparisons among countries.
China and the United States currently produce approximately equal levels of energy-related carbon dioxide emissions and together are responsible for almost half of such emissions worldwide. According to the International Energy Agency’s 2008 World Energy Outlook, China is projected to account for more than 40 percent of new energy-related carbon dioxide emissions globally between 2008 and 2030, thus being by far the largest future contributor to increased concentrations of carbon dioxide in the atmosphere. But in 2006, China instituted a national program to reduce energy intensity 20 percent by 2010; it is noteworthy that in 2006 the energy intensity(energy demand per unit of GDP) decreased by 1.3 percent (that is, energy grew 1.3 percent less rapidly than GDP) and by 3.7 percent in 2007, with greater intensity declines projected for 2008. The program started slowly but is now approaching its annual target.
The United States, meanwhile, has the greatest potential of any country in the world to reduce energy-related greenhouse gas emissions. This is true for two reasons: First, because the U.S. per capita intensity of these emissions is considerably higher than those of other large industrial countries (2.5 times that of the European Union and 2.1 times that of Japan), there is greater opportunity to decrease the numbers; and second, the United States has the scientific, technical, and economic capability of developing viable alternatives to fossil-energy technologies and is likely to be the world leader in any breakthrough technology, if one is developed. Annual growth of energy-related carbon dioxide emissions in the United States in the coming decades is expected to be in the range of 0.5–1.0 percent unless new policies are enacted to cut carbon dioxide emissions.
For the future, neither China nor the United States have agreed to binding commitments on greenhouse gas emissions. In 1992 the U.N. Framework Convention on Climate Change (UNFCC) established an intergovernmental plan to reduce and mitigate greenhouse gas emissions; the resulting agreement is named the Kyoto Protocol. China is a signatory to the Kyoto Protocol, but it actually contains no binding commitment for developing countries. Recognizing that developed countries are principally responsible for the current high levels of atmospheric greenhouse gas emissions as a result of more than 150 years of industrial activity, the Protocol places a heavier burden on industrialized nations. As of 2008, the United States had not ratified the Kyoto Protocol.
In describing contributions of a country, it is useful to present this in terms of per capita emissions, in the same way that GDP/capita, not GDP, is a measure of the economic well-being of a country. That is, over the entire period during which we can estimate carbon emissions due to human activity (roughly since 1850), China’s cumulative per capita emissions of energy-related CO2 are less than 8 percent of those of the United States.
This is generally seen as a remarkable achievement, as virtually all countries undergoing very rapid economic development—China had 9–10 percent annual GDP growth over those two decades—experience energy growth that is faster than GDP growth. China’s reduction in energy demand growth was the consequence of explicit policies carried out in China. If energy had grown just at the rate of GDP, China’s emissions of CO2 would be more than twice as great as today’s emissions.
Notwithstanding these reductions in growth of CO2 emissions, U.S. CO2 emissions per capita are 2.5 times greater than those of the European Union countries and 2.1 times those of Japan. The European Union and Japan are not far behind the United States in GDP/capita. However, these nations have much less land per capita and have much higher population densities. High population density reduces travel demand and results in smaller per capita emissions.
Two Viewpoints
It is generally not understood in the West that China has put tremendous effort into reducing the growth of energy-related carbon dioxide emissions through the design and implementation of aggressive and innovative energy efficiency policies. Instead, there is a perception that China has paid little attention to the matter of greenhouse gas emissions. From 2001 to 2006, China’s energy demand and energy-related carbon dioxide emissions grew faster than the 10 percent annual growth of GDP. This led to an increase in China’s emissions from 12.7 percent of global emissions (2001) to 18.4 percent (2006). Many in the United States look at these facts, noting how rapidly China has grown in the past five years, and are aware of the forecasts that predict that a large proportion of the world’s expected increase in energy-related carbon dioxide emissions this century will come from China. Many Americans express concern that emissions reductions applied to the United States could increase the cost of producing goods and services there, thus placing the U.S. at a competitive disadvantage with any country that does not do the same.
But the perspective from China is very different. The Chinese note that per capita energy consumption and carbon dioxide emissions are much lower in China than in the United States. They emphasize the disproportionate cumulative contribution of the United States to the global greenhouse gas problem, pointing out that the United States, with a population one-quarter the size of China’s, is responsible for putting far more carbon dioxideinto the atmosphere than has China. This point is made to indicate the inequity inherent in focusing on current emissions while a large part of the problem is caused by emissions over long periods of time.
These views may provide a philosophical underpinning that supports China’s major concern looking forward: China believes that it will need more energy for development—much more. Chinese officials observe that the industrialized countries have already been through the energy-intensive phase of their development, but China is in the midst of its own. The possibility of gaining a competitive trade advantage through a new climate treaty is much less significant to the Chinese than the possible roadblocks to achieving social development goals that could result from a commitment to mandatory emissions targets.
Efforts Towards Cooperation
It is not enough that China and the United States both take steps to reduce carbon dioxide emissions; it is essential that the two countries do this cooperatively. As long as China does little to reduce growth of greenhouse gas emissions (or appears to be doing little), it will be politically difficult for the United States to sign a binding international treaty that commits to a serious cap on emissions. And as long as the United States either does little or appears to be doing little, it is impossible to imagine China committing to any international treaty that limits its own emissions.
At a 2008 hearing held by the U.S.-China Economic and Security Review Commission, representatives from the China Energy Group proposed that the United States and China should engage in regular, formal discussions that focus on working together to reduce greenhouse gas emissions, with the goal of influencing global negotiations. A serious proposal agreed to by both the United States and China is likely to be acceptable to both industrialized and developing countries.
A research group that has worked with energy policy-makers in China for two decades to analyze, develop, and enhance Chinese energy policy, the China Energy Group further recommended that in the short term, the greatest support the United States can provide to China (and other developing countries) is to build capacity in those countries to create and implement policies and programs that reduce greenhouse gas emissions. Western resources can provide training and technical assistance to Chinese enterprises that will in turn establish new energy standards and compliance regulations. The assistance develops the potential for the Chinese to pursue energy efficiency, but does not pay for it. Such a program also will need to engage the full participation of the international community: It should include all industrialized countries as donors and key developing countries as recipients. This is not an investment program; it is focused on building capabilities to design and implement policies, many of which will facilitate investments with funds coming from other sources.
In the long term, the solution to climate change will have to rely on technology that is not yet commercialized. New low-carbon technologies are essential to reduce energy-related carbon dioxide emissions to appropriate levels. For the most part, such technology is not available today, and the intellectual property for these technologies does not exist yet. There is a need for programs to support joint development of such technologies, using the technical and financial resources of many countries. The United States government could play a key role in establishing a basis for performing research and development on these technologies with other nations (including China) and the sharing of intellectual property of these future technologies among nations of the world.
The China Energy Group also proposed that the leaders of the high-level teams from both countries should be policy makers above the level of the climate-change negotiators. These discussions should not be construed as bilateral negotiating sessions; the goal is for China and the United States to reach a consensus that can serve as a model for the European Union and developing nations. Any agreement must include binding commitments that will not threaten China’s growth and internal development goals, and that will give China access to the knowledge, tools, and technology that lower the cost of reducing emissions; for the United States, it is crucial that implementation of the agreement will not exacerbate the U.S. trade deficit with China. A formula that might work in China is a commitment that industrial emissions would grow slower than the industrial value added over the next decade, for example, 80 percent as fast, after which time a new formula could be agreed upon. The advantage of this approach is that it places no constraint on the consumer economy, which China views as necessary to meet its social and economic development objectives. A further advantage is that this approach addresses the industrial sector, which is responsible for 70 percent of all energy-related emissions; it thus speaks to the activities in China that are by far the largest contributor to greenhouse gas emissions.
There are other formulas that could be used for China as well. Most involve the adoption of an emissions target that increases as GDP increases, thus assuring China that growth would not be impacted as long as proper measures are taken to reduce the growth of greenhouse gases. Like the industrial emissions approach, the formula could involve a commitment that greenhouse gas emissions grow at a rate lower than that of GDP with the provision of technical support, capacity building, and/or funds to facilitate reductions in greenhouse gas emissions. Achieving better results could trigger greater levels of assistance.
Trade Policies
Trade remains a major divisive topic, but there are different ways to deal with this issue. One, for example, is based on the concept of “carbon credits,” a tool formalized in the Kyoto Protocol and monitored by the UNFCC that expects to reduce greenhouse gases by having countries honor their emissions quotas and offers monetary incentives for being below those targets. (This system has been adopted by the European Union, and it has resulted carbon credits of about $20 or $30 per metric ton.) To avoid impact on trade in the case where limits on Chinese emissions in early years would produce only small increases in the price of its products for export, China would agree to a tax on exports equal to the cost of a carbon credit (in dollars per metric ton). To avoid this being too cumbersome, it would apply only to products that are energy- (and therefore carbon-) intensive in their manufacture. Under this proposal, China would collect the tax and be required to apply it to its program of reducing carbon dioxide emissions. A program such as this would eliminate the trade advantage that China might gain by having less rigid commitments than industrial countries. It would have the further benefit of assuring that resources in China would be used to address greenhouse gas emissions.
An international commission would be needed to oversee the uses of the tax in China (and presumably other developing countries, if the approach is extended to them) as well as the provision of resources from the United States and other industrialized countries to support greenhouse gas abatement in developing countries.
Protecting Economic Growth
In the United States, economic growth and energy use over a period of a decade or longer are relatively predictable. Absent a multiyear recession, annual economic growth over a period of a decade or more is likely to be 1.5–3 percent. Growth in annual energy demand and energy-related carbon dioxide emissions, without new policies, is likely to be in the range of 0.5–1.0 percent. (With a long-term recession, the growth of energy demand and carbon dioxideemissions will be at a decreased rate, thus lowering the difference between targets and emissions in a base case.)
Forecasts in this range apply to most industrialized countries, for which many consumer products such as refrigerators and cars have already approached saturation. In short, it is possible to understand at a general level what is entailed in achieving certain targets for greenhouse gas emissions over a period of one to two decades.
But for a rapidly developing country such as China, growth in energy demand and resulting carbon dioxide emissions can have much greater variations. The Chinese economy grew at annual rate of 9–10 percent from 1980 to 2000; during this period energy demand grew at an annual rate of 4–5 percent. (In only one year during this period did the increase in energy demand growth exceed even 60 percent of that of GDP.) But from 2001 to 2006 GDP in China continued its growth at 10 percent per year (or greater). One might have predicted that energy demand in China would have grown at a rate lower than 5 percent per year, as it had done over the previous twenty years; indeed, forecasters did predict this. But energy demand grew even faster than GDP during the period, averaging almost 12 percent per year.
Consequently, it is extremely difficult in China, in its present stage of economic development, to predict with any accuracy the energy-demand growth over a ten- to twenty-year period. This is one reason that China cannot accept a binding cap that is expressed in absolute terms, unless such a cap were well in excess of the higher range of expected emissions. (But if a cap were set so high, it would be meaningless.)
China and other developing countries will have the largest emissions in the future, and there is great concern worldwide that China will continue increasing its energy demand and spewing carbon dioxide into the environment forever, or at least for a very long time. But China is in the middle stage of building its infrastructure—housing, commercial buildings, roads, hospitals, schools, and the like. It is at a relatively early stage of increasing the mobility of its population, and large quantities of energy are required to accomplish these tasks. This period is likely to last for fifteen to twenty-five years, depending on whether China continues its breakneck speed of construction and whether large numbers of rural dwellers continue migrating into urban areas. At the end of this construction period, China’s economy will be much like today’s developed countries. Energy-demand growth will decline markedly, just as it now has in the industrialized world. Scarcity of traditional energy sources could slow energy-demand growth even further in this time.
Outlook for the Twenty-First Century
The key question about the future concerns what China’s energy demand will be when its economy becomes mature, or when infrastructure is built out and most amenities have been met. If China has a structure of consumption similar to that of the United States today, and the construction techniques and industrial processes are inefficient in their use of energy and other resources, then not only China but the world will be in serious trouble. But from 1980 to 2000, China has shown its willingness to grow its economy while constraining energy growth to less than half that of economic growth. Today China exhibits a serious willingness to once again limit energy growth, and significant support from industrialized countries can help greatly in achieving this objective. If at the same time the industrialized countries learn to reduce greenhouse gas emissions—and transfer this knowledge to China and other developing countries—then a sincere start at addressing the serious challenge of climate change will be possible. This approach can buy time while energy supply technologies that produce low carbon emissions are developed and deployed on a large scale.

Economic growth, especially as a result of investment in heavy industry, has rapidly increased China’s share of global energy use. Weak enforcement from Beijing and local authorities who appear to opt for profit over environmental efforts emphasize the need for a stronger energy policy in twenty-first-century China.
Between 1978 and 2000, the Chinese economy grew approximately 9 percent annually while energy demand increased 4 percent. At the turn of the twenty-first century, China accounted for 10 percent of global energy demand but met 96 percent of this demand with domestic energy supplies. After 2001, however, economic growth continued apace, but changes in the structure of the economy pushed energy demand up. By 2006, China’s share of global energy use swelled to over 16 percent, forcing the country to rely on international markets for more of the oil, gas, and coal it consumes.
This fundamental shift in China’s energy profile has created both shortages at home and market volatility abroad and raised questions about the sustainability of China’s growth curve. According to the International Energy Agency, China is now the world’s second-largest energy consumer and has likely become the leading source of greenhouse gas emissions.
Evolution of Energy Demand in China
Decades of state planning and ideological aspiration prior to reform in the late 1970s had distorted China’s energy demand profile. Rather than embracing a development strategy compatible with its natural endowments as Japan, Hong Kong, Taiwan, and others had done, Chinese leaders ignored a comparative advantage (that China is rich in labor but poor in capital, arable land, and technology) and dragged China—kicking, screaming, and sometimes starving—toward Soviet-style industrialization. For thirty years, resources sporadically were shifted out of agriculture and into energy-intensive industries like steel and cement. Data from within China claims that between 1949 and 1978, industry’s share of economic output grew from 18 to 44 percent, and the amount of energy required to produce each unit of output tripled.
This command-and-control fiasco resulted in severe inefficiency. In 1978 leaders began to unleash China’s potential. Beijing reformed agricultural production targets and let prices rise, with dramatic results. Farm output increased, and the early 1980s saw rural residents with more time on their hands, cash in their pockets, and freedom to use it as they chose. Much of this new wealth was invested into township and village enterprises (TVEs) set up to exploit what China was best suited for: labor-intensive light manufacturing.
Reform also brought changes within heavy industry, which reduced the energy intensity of Chinese growth. Economic incentives—such as the right to keep profits—were introduced, and awareness of bottom-line profits made enterprises focus more on top-line expenses, including energy. As enterprises were becoming more aware of the impact of energy costs on profitability, their energy bills were growing as a result of the partial relaxation of oil, gas, and coal prices. The introduction of limited competition for both customers and capital, not just from other state-owned enterprises (SOEs) but also from a growing private sector, made energy cost management all the more important. Domestic competition was accompanied by a gradual integration with world markets; lower trade barriers not only exerted pressure on SOEs from energy-efficient foreign companies but also allowed them to acquire the more energy-efficient technology their competitors enjoyed. China’s small existing base of modern plants and equipment enabled it to absorb new technology quickly, significantly improving the efficiency of the country’s capital stock.
By 2000, Chinese economic activity required two-thirds less energy per unit of output than in 1978. Energy intensity improvement on this scale was unprecedented for a large developing country, and it meant that in 2001, China accounted for 10 percent of global energy demand rather than the 25 percent that had been projected based on its 1978 energy performance.
Investment-Led Energy Surprise
At the start of the new millennium in 2001, China’s leaders expected the energy intensity improvements that had been taking place since 1978 to continue. Most energy forecasters at home and abroad assumed that the structural shift away from energy-intensive heavy industry would persist; at least, no one expected the evolution to reverse quickly.
In 2001 both the Chinese government and the International Energy Agency (IEA) predicted 3 to 4 percent energy demand growth between 2000 and 2010.
In actuality, both wildly missed the mark. The economy grew much quicker than anticipated from 2001 to 2006, but the real surprise was a change in the energy intensity of economic growth: Energy demand elasticity (the ratio of energy demand growth to gross domestic product, or GDP, growth) increased from 0.4 (during 1978–2001) to 1.1 (2001–2006). In 2006, energy consumption in China grew to 16 percent of global demand, four times faster than predicted. And yet on a per capita basis, China’s energy demand remains one-sixth that of the United States, triggering anxiety about how much more growth is yet to come.
This discovery not only shocked domestic and international energy markets but also prompted a fundamental reassessment of China’s energy future—and hence the world’s. In its 2007 World Energy Outlook, the IEA raised its 2030 forecast for China’s energy demand to 3.8 billion tons of oil equivalent, up from the 2.1 billion tons it had predicted in its 2002 outlook—a 79 percent upward revision. Under this scenario, China will account for 22 percent of global energy demand, more than Europe, Russia, and Japan combined, easily surpassing the United States as the world’s largest energy consumer.
What caused China’s two-decade history of energy intensity improvements to change course? Many authorities assume that the recent evolution of China’s energy profile reflects growth in consumption and transportation—for instance, air conditioning and personal cars—but this is not correct. Consumption-led energy demand will be a major force in the future, and it is already significant in absolute terms, but the main source of current growth is energy-intensive heavy industry. Industrial energy efficiency has continued to improve over the past six years; every new steel mill is more efficient than the last one. But the late-twentieth-century structural shift away from heavy industry toward light industry has reversed, and a new steel plant—no matter how much more efficient than its predecessor—uses substantially more energy than a garment factory. The IEA asserts that industry accounts for two-thirds of final energy consumption in China today, while the residential, commercial, and transportation sectors account for 12, 5, and 13 percent, respectively.
This industrial energy consumption is high by either developed or developing country standards. (See Table 1.) But when pundits express shock at how much more energy intensive China is than Japan, for example, they usually ignore the important factor of what the country makes. High energy-intensity partly reflects the role of industry in the Chinese development model, as opposed to India, which has taken a more services-heavy approach, or Japan, which has lowered its energy intensity in part by relocating its energy-intensive sectors to China. According to Chinese statistics, industry accounts for 48 percent of all economic activity in China, compared with India at 29 percent and Japan at 26 percent. So the fact that one unit of economic output requires five times as much energy in China as in Japan says more about the type of economic activity taking place in China than the efficiency with which it occurs.

Increasingly, economic activity in China is slanted toward capital investment, and from an energy standpoint, the current investment cycle is different than in the past. Rather than importing, China is now producing domestically more of the energy-intensive basic products (such as steel and aluminum) used to construct the roads and buildings for which investment pays. China now accounts for 49 percent of global flat glass production, 48 percent of global cement production, 35 percent of global steel production, and 28 percent of global aluminum production. Some of this production also reflects the migration of industry from other parts of the world not only to meet domestic demand in China but also for export. Whereas China used to be a net importer, it has now become a major global exporter of steel, aluminum, and cement.
The changing composition of China’s industrial structure is also a result of competition among provinces and localities to grow GDP, tax revenue, and corporate profits. Not just Beijing but also local interests (including industrial enterprises) set the rules of competition. And regardless of who sets the rules, implementation is a local matter. Within this context of competition, short-term economic incentives—specifically low operating costs and profits—explain much of the increase in heavy industrial activity.
After-tax earnings in energy-hungry industries have been good, rising from near zero in the late 1990s to a level comparable to that of their light-industry counterparts—ranging from 4 to 7 percent in steel, glass, chemicals, and cement in recent years. With China modernizing over 170 cities of more than 1 million people, certainly there is a large domestic market for basic materials; supply was squeezed by breakneck growth after 2001. But with overcapacity arising almost as soon as the first profits come in, the ability of firms to sell surplus production in international markets has been critical to remaining profitable.
China’s energy-intensive industry enjoys low operating costs, which has allowed for rising profit margins and a dramatic growth in capacity that is at the center of China’s overinvestment in heavy industry. Local governments often provide deeply discounted land, and they often do not enforce regulations to protect air and water. Construction time is short, and labor costs are low. These benefits apply to all industries, however, they are particularly valuable in the energy-intensive sector, where capital costs are large.
Energy Prices and Environmental Costs
Energy prices in China, once highly subsidized, have gradually converged with world prices over the past thirty years. Yet, it can be difficult to accurately assess the price a specific firm pays for coal, gas, oil, or electricity. Chinese prices for raw energy commodities (including coal and natural gas), particularly in interior provinces close to resource deposits, can be significantly cheaper than elsewhere in the world. For coal, low prices result not from subsidization but rather from low extraction costs in areas isolated from international markets; as obstacles to transportation ease, coal prices will rise toward world prices.Beijing also directly controls natural gas prices, attempting to keep them competitive with the Middle East. But this approach has failed to encourage development and delivery of sufficient quantities of natural gas to meet demand, and authorities are allowing domestic prices to increase.
China’s industry increasingly receives its energy in electrical form, and reported prices of electricity are high compared with those in developing and some developed countries; only in Germany, the United Kingdom, and Japan are costs greater. However, based on conversations with Chinese business leaders and industry analysts, it is likely that many industrial enterprises do not bear the full cost provided by national average figures from the Statistical Bureau. China’s National Development and Reform Commission (NDRC) sets electricity tariffs province-by-province based on the recommendations of local pricing bureaus, which answer to local officials. While the NDRC would like to see energy pricing rationalized to reduce overall energy consumption, it is sensitive to local social and economic development concerns.
Energy prices in China have not reflected environmental costs historically. Over 80 percent of the country’s electricity is generated from coal. But at the end of 2006, less than 15 percent of coal power plants had flue gas desulphurization (FGD) systems (used to remove sulfur dioxide from emissions streams) installed and even fewer had them running. Operating an FGD system reduces production efficiency by 4 to 8 percent and therefore contributes to higher electricity prices. If all the power plants in China installed and operated FGD systems, average electricity tariffs could rise by 10 to 20 percent. Industries that burn coal directly (such as steel and cement) are subject to sulfur taxes, but these are generally too low to reduce pollution. Other air pollutants, such as nitrogen dioxide and mercury, are largely unregulated. Regulated or not, enforcement generally falls to the provincial and local governments, which must balance environmental concerns against economic growth priorities. In the absence of a strong environmental regulator, like the U.S. Environmental Protection Agency, that balance is skewed toward near-term economic growth, as industry threatens to cut jobs and tax revenue if enforcement of environmental regulations is increased.
While it is a daunting and subjective challenge to compute the external impacts of China’s penchant for heavy industry, it is important to recognize that they exist: China does not necessarily do the world a favor by overproducing. Moreover, there are other effects to be considered. A rebalanced China, better aligned with its natural endowment of labor, could be a bigger economy, grow faster, and be less prone to collapse; hence it would be a better engine of world growth. Also, heavy industry in China is less likely to attract innovation and technological change due to weaknesses in intellectual property protection and the difficulty of recovering research-and-development investments. Similarly, institutional weaknesses in regulation and enforcement of pollution controls undermine the process of finding innovative ways to remedy environmental damage.

China currently emits more CO2 into the world’s atmosphere than any other country (but not more per capita). It faces international pressure to control these emissions because they are a primary cause of climate change, but China claims it should not be held responsible for CO2 “export emissions” that can be attributed to the production of items for export to the United States and other nations.
It is an accepted fact that China’s exports are responsible for large amounts of greenhouse gas emissions; in 2005, carbon dioxide emissions from China were estimated at 1700 Mt (million metric tons, compared to around 30,000 Mt emitted by humans due to fossil fuels each year), or 6 percent of global emissions from fossil fuels, which is unusually high, as US exports are about 500 Mt. Reacting to international demands to reduce greenhouse gases, China has claimed that limits on carbon dioxide emissions would hamper both economic development and its efforts to relieve poverty. It has also emphasized that per capita emissions ranked only seventy-third in 2004, but this ranking is higher than some developed countries, and it is growing rapidly.China also argues that its historical, cumulative contribution to carbon emissions is low, and while this is true on a per capita basis (China ranked ninety-second in cumulative emissions from 1900 to 2004), it is fourth in cumulative emissions since 1990. A final argument against mandated emissions limits is related to the role of exports (that is, products made in China for sale elsewhere): China claims that it should not be held responsible for emissions that can be attributed to the production of items for export to the United States and other nations.
Gauging the contribution of exports to China’s carbon dioxide emissions is not easy, but they have clearly risen dramatically over the past decade. A 1997 study by the ecologists Ahmad and Wyckoff found that 15 percent of China’s emissions were “embodied” in products to be exported to other countries (that is, they were the byproduct of the manufacturing of toys, electronics, shoes, and other exports, while only 3 percent of China’s domestic emissions were imported. By 2001, further studiesfound that the figures had increased to 24 percent and 7 percent respectively, showing that a larger volume of goods was being traded. But the export amount is still much higher than that of imports, as one would expect from the current balance of trade between China and, for example, the United States.
Export Growth
In 1987, 12 percent (230 Mt) of China’s domestic carbon dioxide emissions were created during the production of exports; by 2005, this figure steadily had risen to 33 percent (1700 Mt). These numbers closely mirror the rise of exports as a percentage of China’s gross domestic product (GDP), which suggests that export products are no more or no less carbon-intensive than products for domestic consumption.
Of China’s 1700 Mt of export emissions in 2005 (which was comparable to the 1850 Mt total emissions of Germany, France, and the United Kingdom), 22 percent came from exports of electronic goods, 13 percent from metal products, 11 percent from textiles, and 10 percent from chemical products. The recent surge in export emissions can be attributed to value-added products, which is evident when compared to previous years. In 1995, for example, the breakdown was very different: 19 percent textiles, 13 percent electronics, 12 percent machinery, 10 percent chemicals, and 7 percent metal products. Emissions embodied in primary product exports—such asminerals, raw timber, raw chemicals, and basic metals—decreased from 20 to 24 percent during the years from 1987 to 1992 to only 13 percent during the years from 2002 to 2005, showing how the Chinese economy has evolved into producing higher value-added items, such as electronics, which are more valuable as a product than their parts combined.
International attention to China’s role in causing—and mitigating—climate change shows how important trade is in the environmental profile of many countries. In general, small countries have larger shares of domestic emissions from the production of exports (for example, most European countries have a 20 to 50 percent share) while relatively self-sufficient countries have lower shares (such as the United States with 8 percent, Japan with 15 percent, India at 13 percent, and South Korea, 28 percent). China does not fit into this categorization because it is a large country with a large share of exports contributing greenhouse gases; its exports therefore play a more important role in its environmental profile.
Environmental Implications
Experts question whether the rapid growth of exports in China (or any other country) comes at the loss of production in developed countries, a phenomenon termed “carbon leakage” or the “pollution haven hypothesis.” The Intergovernmental Panel on Climate Change (IPCC), the international group that represents the consensus on climate change science, has not rated carbon leakage as very important, because its definition of leakage only considers marginal emission changes in nonindustrialized countries that have been caused by climate policy in industrialized countries. It remains unlikely, however, that this is the case in China, where the increase of emissions is most likely a byproduct of China’s other advantages for production—in particular, lower environmental standards and lower labor costs.
A large proportion of goods responsible for China’s export emissions go to the developed world: approximately 27 percent to the United States, 19 percent to the twenty-seven European Union countries, and 14 percent to the other remaining Annex B countries, mainly Japan, Australia, and New Zealand. (Annex B countries are those industrialized nations that have agreed to emissions caps according to the Kyoto Protocol, a binding intergovernmental agreement signed in 1992.) While approximately 40 percent of China’s export emissions go to other developing nations, flows to these countries may displace their own domestic production or production from another trading partner that might have produced goods with less energy intensity than China. (Energy intensity is defined as the energy required per unit of economic output, or energy demand per unit of GDP.) This may be significant becauseproduction is more polluting in China than in many other countries due to inefficient systems and a coal-dominated electricity supply. The apparent low cost of Chinese production comes with other consequences: damage to the Chinese environment and increased energy emissions that contribute to the international risk from global warming. Some energy experts point out that if the Chinese could decrease the cost of the production of environmentally friendly items such as energy-efficient lighting or wind turbines, the effect of emissions would be outweighed by the beneficial impacts of their use.
Potential Solutions
A possible approach to solving the problem of a huge amount of export emissions would be to use monetary or tax policies to discourage large-volume export commodities such as electronics, machinery, metal products, and textiles. But these higher value-added products contribute to China’s economic growth more than primary productslike natural resources, so in a time of economic challenge, this could lead to a loss in competitiveness and higher costs to consuming countries through inflation. Over the long term, it is in the interest of both the West and China to lower the energy and carbon intensity of its production practices, and to cooperate on low-carbon research and development.
While China benefits from export growth in terms of its GDP and balance of trade, consumers in developed countries also benefit. For this reason, there are efforts to hold consumers in developed countries at least partially accountable for emissions occurring because of the demand for low-priced goods. If consumers were to take some responsibility for China’s export emissions, it is conceivable that China would be more willing to play an active role in post-Kyoto climate commitments. And if China does not want to be held wholly responsible for its export emissions (as it claims), then it must at least be held responsible for what it imports. This could become important in the future, as China shifts to more of a consumption-driven economy.
Although one-third of China’s carbon dioxide emissions result from the production of exports, the remaining two-thirds need to be addressed as well. Inefficient, coal-dominated electricity production is the major cause of China’s carbon dioxide emissions, accounting for 44 percent in 2005. Urgent improvements are needed in this sector. Increasing efficiency in manufacturing as well as domestic and commercial building and in transportation is essential. Other solutions are expanding renewable energy generation and investing in new technologies such as carbon capture and sequestration (CCS), which seeks to develop ways to capture, purify, and store carbon dioxide instead of releasing it and contributing to climate change. Allowing parties to the Kyoto Protocol to shoulder some of the incremental cost of CCS as part of their commitment to decrease greenhouse gas emissions would be a first step, as this would allow importers of China’s carbon-intensive, emissions-producing goods to invest in lowering the carbon intensity of what they buy.
