Jornal Do Brasilia - China first-quarter emissions fell despite rising power demand

China emits more planet-warming greenhouse gases such as carbon dioxide than any other country. It plans to peak carbon emissions by 2030 and achieve carbon neutrality by 2060.

It has invested heavily in its renewable energy sector, building almost twice as much wind and solar capacity as every other country combined, according to research published last year.

New wind, solar and nuclear capacity meant China's CO2 emissions fell by 1.6 percent year-on-year in the first quarter and one percent in the 12 months to March, said analyst Lauri Myllyvirta at the Centre for Research on Energy and Clean Air (CREA).

The analysis is based on official figures and commercial data.

China's emissions have dipped before, but those reductions were driven by falling demand, such as during strict Covid lockdowns in 2022.

This time the drop came despite China's total power demand surging 2.5 percent in the first quarter, said the report published in Carbon Brief.

"Growth in clean power generation has now overtaken the current and long-term average growth in electricity demand, pushing down fossil fuel use," Myllyvirta said.

"The current drop is the first time that the main driver is growth in clean power generation."

Power sector emissions fell 5.8 percent in the first quarter, offsetting rises in emissions from coal use in the metals and chemicals industries.

- 'Hangs in the balance' -

But the report cautioned that emissions could rise again if Beijing seeks to stimulate carbon-intensive sectors in response to its trade war with Washington.

China also remains "significantly off track" for a key 2030 target to reduce its carbon intensity -- carbon emissions relative to GDP -- under the Paris climate agreement.

China pledged to achieve a 65 percent reduction in carbon intensity by 2030 from 2005 levels.

"The future path of China's CO2 emissions hangs in the balance, depending on trends within each sector of its economy, as well as China's response to (US President Donald) Trump's tariffs," Myllyvirta said.

Beijing has agreed to a 90-day pause on sky-high tariffs with Washington, but the shape of a final truce remains unclear.

China has sought to position itself as a leader in combating climate change at a time when Trump is promoting fossil fuel extraction and has withdrawn from multilateral climate agreements.

Last month, President Xi Jinping pledged China's efforts to combat climate change "will not slow down" despite the changing "international situation".

He also said China would announce 2035 greenhouse gas reduction targets, known as Nationally Determined Contributions (NDCs), before COP30 in November, and that it would cover planet-warming gases, not just carbon dioxide.

Despite China's renewable energy boom, coal remains a vital part of its energy mix.

China began construction on 94.5 gigawatts of coal power projects in 2024, 93 percent of the global total, according to a February report by CREA and US-based Global Energy Monitor.

Much of that is expected to be for backup power, however.

Last month, China said that wind and solar energy capacity had surpassed mostly coal-based thermal capacity for the first time, according to data for the first quarter.

To sustain momentum, China now needs a "paradigm shift", energy thinktank Ember said in a report this week, "from chasing 'megawatts' to engineering a 'megasystem'".

The group said China should focus on advanced heating systems for heavy industry, AI-powered smart grids, improved storage for renewable-generating power and carbon removal technology to deal with remaining emissions.
