China needs to expand its efforts to reduce carbon emissions to help hold back the rise in global temperatures, US envoy John Kerry said Thursday.
The State Department said Kerry told Chinese Vice Premier Han Zheng in a virtual meeting that there is "no way" for the world to solve the climate crisis without China's "full engagement and commitment".
China is the world's largest carbon emitter, producing an estimated 27% of global greenhouse gases, followed by the United States.
Kerry is in the eastern Chinese port city of Tianjin for talks on stronger efforts to curb rising temperatures to no more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) over pre-industrial levels.
Global decarbonising efforts will come under the spotlight at a UN conference to be held in Glasgow, Scotland, in late November known as COP26.
"Secretary Kerry emphasised the importance of the world taking serious climate actions in this critical decade and strengthening global climate ambition," the State Department said in a statement.
China's official Xinhua News Agency quoted Han as telling Kerry that China had made "huge efforts" in tackling climate change and had achieved "remarkable results".
China "hopes the American side will create the appropriate circumstances for jointly tackling climate change based on the spirit of the conversations between their leaders," Xinhua quoted Han as saying.
Kerry made a stop in Japan on Tuesday to discuss climate issues with Japanese officials before heading to China.
On Wednesday, Chinese Foreign Minister Wang Yi warned Kerry that deteriorating U.S.-China relations could undermine cooperation between the two on climate change.
Such cooperation cannot be separated from the broader relationship, Wang told Kerry by video link.
Relations between Washington and Beijing have been strained by disputes over trade, technology and human rights. However, the two sides have identified the climate crisis as an area for possible cooperation following US President Joe Biden's decision to rejoin the the 2015 Paris climate accord.
China obtains roughly 60% of its power from coal and is opening more coal-fired power plants, while also committing to reducing its use of the fossil fuel.
Beijing has pointed to historical US emissions as a reason to resist action while making advances in solar power and other renewable energy sources. The country has set a target of generating 20% of its total energy needs from renewables by 2025, becoming carbon-neutral by 2060 and reducing total emissions starting from 2030.
Biden has announced a goal of cutting up to 52% of US greenhouse gas emissions by 2030 - double the target set by then President Barack Obama in the Paris agreement. The 2030 goal vaults the US into the top tier of countries on climate ambition.
