China opened a national carbon market; here’s why it matters
CHINA, the world’s biggest source of greenhouse gas pollution, opened a national carbon emissions trading market Friday, a long-awaited step aimed at fighting climate change.
The market turns the power to pollute into an allowance that can be bought and sold and is part of an array of policies that the Chinese government is putting in place as it tries to demonstrate its commitment to significantly reducing carbon dioxide emissions in the coming decades.
Here is how the program works and what it could do.
The market is key to China’s climate ambitions.
China’s leader, i inping, has sought to cast his country as an environmentally responsible world power and has pledged to tackle climate change. The new carbon market, which will immediately be the world’s largest by volume of emissions, is the latest of Beijing’s efforts.
Last year, i made two signature commitments on climate. China’s emissions of carbon dioxide would peak before 2030, he vowed. It would also achieve carbon neutrality before 2060, he said, meaning the amount of carbon dioxide gas China releases into the atmosphere would be offset through methods like planting forests.
i’s pledges, if realized, could make a significant difference to the world’s efforts to fight climate change. An international pact aiming to limit global warming this century to below 2 degrees Celsius (3.6 degrees Fahrenheit), and to 1.5 degrees Celsius, if possible, will not be feasible unless China and the other major powers act urgently to cut greenhouse emissions.
China has come under intense pressure at home and abroad to cut emissions and do more to reduce global warming since it overtook the United States as the biggest polluter around 2006. In 2019, China’s greenhouse gas output accounted for 27 of global emissions, more than the combined total of the next three biggest emitters the United States, the European Union and India according to the Rhodium Group.
Here is how carbon emissions trading works.
These markets work by limiting the amount of carbon dioxide that companies can release, creating competition to encourage them to become more energy efficient and
adopt clean technology.
Companies that cut their carbon output can sell their unused pollution allowances those that exceed their emissions allowance might have to buy more permits or pay fines.
By auctioning allowances and progressively cutting the
volume of pollution that companies are allowed to release, governments can push companies into a race to adopt carbon-cutting technologies.
Emissions trading can be a more efficient and flexible tool for cutting emissions than topdown administrative measures, hao ingmin, a Chinese vice minister for the environment, told a news conference in Beijing on Wednesday.
“It can place responsibility for containing greenhouse gas emissions on businesses and can also provide an economic incentive mechanism for carbon mitigation,” he said.
China’s carbon market was years in the making.
The Chinese government started local trials of carbon trading more than a decade ago. In a summit with President Barack Obama in 2015,
i made establishing a national trading program a cornerstone of climate cooperation with the United States.
But Chinese authorities have struggled to get the settings right for a national launch.
To make the market work, regulators must accurately measure emissions from factories and plants, then ensure that those polluters do not cheat by hiding or manipulating emissions data.
But that can be challenging in China, with its sprawling industrial base and relatively poor regulation. A firm from Inner Mongolia, a region of northern China, that is participating in the new market, was already fined this month for falsifying carbon emissions data.
The Chinese government initially said that the market could cover steelmaking, cement and other industries as well as power plants. But it narrowed the scope to cover only coal and gas plants that supply power and heat a sector that has fewer players and is easier to monitor. Other industries may be brought into the market in coming years.
