“Washington is obliged to set an example for mankind’s efforts against global warming, and now the Trump administration has become the first government of a major power to take opposite actions on the Paris Agreement,” the newspaper said. “It is undermining the great cause of mankind trying to protect the earth, and the move is indeed irresponsible and very disappointing.”
The editorial also questioned why China was making concessions on fossil-fuel use when the United States was scrapping its promises: “How can China, still underdeveloped, give away a chunk of room for development, just to nourish those Western countries that are already rich?”
Chinese participation is critical for global efforts on climate change. With its economic growth and rampant infrastructure construction, China consumes as much coal as the rest of the world combined. The burning of coal, which is at the core of the power, steel and cement industries in the country, generates enormous amounts of carbon dioxide, the main greenhouse gas. So environmental advocates and officials around the world constantly say China must break its coal addiction.
But unlike in the United States, Chinese leaders and senior officials have consistently said that climate change is a serious problem and acknowledged that changing the energy mix to move away from fossil-fuel sources is important.
And because of its air pollution crisis, China announced policies in 2013 to limit the use of coal in the country’s three largest population centers. More recently, scientists have said that there is a dangerous cycle at work: Weather patterns from climate change are exacerbating the smog.
“China is cutting back on coal because of its lethal costs to human health as well as its high carbon emissions, and plans to transition to the energy sources of tomorrow, rather than yesterday,” said Isabel Hilton, founder of Chinadialogue, a prominent website that reports on environmental issues and policy. “President Trump seems intent on reviving a 19th-century energy source rather than pursuing the promise of the 21st century.”
Mr. Trump’s pro-coal talk, and the unlikelihood that his administration will pressure China to cut back on fossil fuels, might mean that pro-coal interests in China, including among state-owned energy companies, will try harder to push back against officials putting limits on coal.
But in recent years, coal consumption in China has declined slightly, surprising many analysts and researchers. China’s economic slowdown — from decades of double-digit annual growth to 6.7 percent last year — has been a major factor. Analysts say there appeared to be an increase in coal use during part of 2016 because of economic stimulus policies, but preliminary statistics released in February indicate that overall coal consumption declined last year compared with 2015.
Given such numbers, researchers say China may reach a carbon emissions peak in 2025 — five years ahead of its stated goal of 2030.
China has also made pledges on the percentage of total energy that will be generated by non-fossil-fuel sources, which include hydropower, nuclear power, wind and solar. Mr. Xi has said that by 2030, 20 percent of China’s energy will come from such sources. Chinese officials are now grappling with the complex problem of getting energy generated by wind and solar sources onto the grid and properly used.
“Trump’s rejection of regulatory action on climate change creates a vacuum in global climate leadership that China can now seize,” said Alex L. Wang, a law professor and China environmental expert at the University of California, Los Angeles. “In recent years, a variety of factors — crisis levels of pollution, economic opportunities from green development and concerns about the domestic risks of rising temperatures — have pushed China to action on climate change. Trump’s actions don’t affect these underlying drivers.”
In addition, China has said that it will put in place by the end of this year a national market for greenhouse gas quotas, commonly known as a cap-and-trade program. It has experimented with seven such regional markets, and there have been problems with them, but the government is determined to set up a national program to put a price on carbon and impose a cost on companies that generate large amounts of carbon dioxide, Chinese policy advisers say.
China appears to be overperforming on other targets besides its carbon emissions peak date. It had stated that by 2020, 58 percent of its energy would come from coal consumption. Official statistics indicate China might meet that target early. Chinese officials now say they expect to get the number down to 60 percent this year.
A report released in January by the Institute for Energy Economics and Financial Analysis, based in Ohio, said China was the world leader in domestic investment in renewable energy and associated low-emissions-energy sectors, with $103 billion invested in 2015. And China is going global with that strategy — last year, it invested $32 billion in large overseas deals involving renewable energy.
“There are clear differences between the Chinese approach and the Trump administration on climate change,” Ms. Hilton said. “While Trump’s administration seems to believe that action on climate change is a waste of money and threatens jobs in the U.S., China sees investment in climate-related action as essential to secure a safe and prosperous future for Chinese citizens, as well as a strategic opportunity to develop and supply the technologies of the future.”
