China, world's top carbon pollutor, likely to overdeliver on climate goals. Will that be enough?

China is likely to overdeliver on the modest goals the government has set to cut carbon pollution, experts say. China's 2035 goals, a 35-page document submitted Monday, adds detail to the broad targets announced by leader Xi Jinping in late September. All countries that signed the 2015 Paris Agreement on climate are required to update their goals, called “Nationally Determined Contributions,” every five years.
