China Steps into the Spotlight at UN Climate Talks

China’s emissions-reduction pledge is set to dominate discussions at a United Nations climate summit on Wednesday, following a sharp, if predictable, critique from US President Donald Trump questioning the science of fossil-fuel-driven global warming.

Some 118 nations are expected to outline plans to curb global warming, which is triggering disasters worldwide—from catastrophic floods in Pakistan to raging wildfires in Spain—even as many continue to expand oil and gas production.

Chinese Premier Li Qiang will open the session at UN headquarters in New York. China, responsible for around 30% of global greenhouse gas emissions from factories, power plants, vehicles, and other sources, is expected to provide a crucial update: its 2035 emissions-cutting target.

China has never committed to directly reducing carbon dioxide. Instead, it pledged to peak emissions before 2030—a goal it appears poised to meet five years early, thanks to rapid growth in solar energy and electric vehicles.

In contrast, many wealthy nations—historically the largest contributors to warming—peaked emissions decades ago but still lack credible plans to achieve carbon neutrality by 2050.

“All eyes will be on China,” said Li Shuo, an expert at the Asia Society think tank.

Li Shuo anticipates a “single-digit to low double-digit” percentage reduction commitment over the next decade, mirroring the pace the US and EU achieved in the decade following their emission peaks.

While this trajectory falls short of what is required to limit warming to 1.5°C above pre-industrial levels—the goal of the 2015 Paris Agreement—it demonstrates China’s engagement with the international process ahead of COP30 in Belem, Brazil.

Li Shuo notes that overemphasis on the figure risks overlooking China’s status as “the green tech superpower of the world”, with a track record of under-promising but over-delivering.

For the UN summit, Secretary-General Antonio Guterres invited only nations ready to present or announce new 2035 climate targets.

Under the Paris Agreement, nearly all nations (except Iran, Libya, and soon the US) set their own targets but must strengthen them every five years. Many countries are behind schedule, notably in the EU, where some states fear economic harm from rapid decarbonisation.

France, for example, faces financial and political challenges and seeks clearer investment frameworks before committing to deeper emission reductions.

“There’s a current shortfall in ambition demonstrated by countries we traditionally look to for leadership, which are acting more like climate laggards,” said Ilana Seid, ambassador to the UN for Palau and chair of the Alliance of Small Island States.

The UN is attempting to strike a balance between warning of impending climate disasters and maintaining hope.

Secretary-General Antonio Guterres warned last week that the chances of keeping warming to 1.5°C are “on the verge of collapsing,” a view supported by climatologists, with current temperatures already around 1.4°C above pre-industrial levels.

Conversely, UN Climate Change Executive Secretary Simon Stiell insists the Paris process is delivering results.

“Without UN climate cooperation, we were heading for five degrees of heating—an impossible future. Today we are closer to three. Still too high—but bending the curve,” he said at Climate Week in New York.

A decade ago, three-quarters of China’s electricity came from coal; today, this has fallen to around 50%.

China’s exports of solar panels, batteries, and electric vehicles are further reducing emissions abroad, underlining its growing role as a global climate leader.

The summit will test whether China can translate domestic progress into credible international commitments, while other major powers struggle with internal political and economic constraints.
