Climate Action Tracker says that China’s target is “unlikely to drive down emissions”, because it was already set to achieve similar reductions under current policies.
In addition to a headline emissions reduction target, Xi also pledged to expand non-fossil fuels as a share of China’s energy mix and to continue the rollout of wind and solar power.
This continues the trend in China’s previous NDC.
Notably, however, Xi made no mention of efforts to control coal in his speech.
In its second NDC, focused on 2030, China had pledged to “strictly control coal-fired power generation projects”, as well as “strictly limit” coal consumption between 2021-2025 and “phase it down” between 2026-2030. It also said China “will not build new coal-fired power projects abroad”.
It remains to be seen if coal is addressed in China’s full NDC for 2035.
The 2030 NDC also stated that China would “increase the share of non-fossil fuels in primary energy consumption to around 25 per cent” – and Xi has updated this to 30 per cent by 2035.
These targets are shown in the figure below, alongside recent forecasts from the Sinopec Economics and Development Research Institute, which estimated that non-fossil fuel energy could account for 27 per cent of primary energy consumption in 2030 and 36 per cent in 2035.
As such, China’s targets for non-fossil energy are less ambitious than the levels implied by current expectations for growth in low-carbon sources.

In a recent meeting with the National People’s Congress Standing Committee – the highest body of China’s state legislature – environment minister Huang Runqiu said that progress on China’s earlier target for increasing non-fossil energy’s share of energy consumption was “broadly in line” with the “expected pace” of the 2030 NDC.
On wind and solar, China’s 2030 NDC had pledged to raise installed capacity to more than 1,200GW – a target that analysts at the time told Carbon Brief was likely to be beaten. It was duly met six years early, with capacity standing at 1,680GW as of the end of July 2025.
Xi has set a 2035 target of reaching 3,600GW of wind and solar capacity.
This looks ambitious, relative to other countries and the global capacity of around 3,000GW in total as of 2024, but it represents a significant slowdown from the recent pace of growth.
Given its current capacity, China would need to install around 200GW of new wind and solar per year and 2,000GW in total to reach the 2035 target. Yet it installed 360GW in 2024 and 212GW of solar alone in the first half of this year.
Myllyvirta tells Carbon Brief this pace of additions is “not enough to even peak emissions [in the power sector] unless energy demand growth slows significantly”.
While the pace of demand growth is a key uncertainty, a recent study by Michael R Davidson, associate professor at the University of California, San Diego, with colleagues at Tsinghua University, suggested that deploying 2,910-3,800GW of wind and solar by 2035 would be consistent with a 2°C warming pathway.
Davidson tells Carbon Brief that “most experts within China do not see the [recent] 300+GW per year growth as sustainable”. Still, he adds that the lower levels outlined in his study could be consistent with cutting power-sector emissions 40 per cent by 2035, subject to caveats around whether new capacity is well-sited and appropriately integrated:
“We found that 40 per cent emissions reductions in the power sector can be supported by 3,000-3,800GW wind and solar capacity [by 2035]. Most of the capacity modelling really depends on integration and quality of resources.”
Renewable energy’s share of consumption in China has lagged behind its record capacity installations, largely due to challenges with updating grid infrastructure and economic incentives that lock in coal-fired power.
In Davidson’s study, capacity growth of up to 3,800GW would see wind and solar reaching around 40 per cent of total power generation by 2030 and 50 per cent by 2035.
Meanwhile, China will need to install around 10,000GW of wind and solar capacity to reach carbon neutrality by 2060, according to a separate report by the Energy Research Institute, a Chinese government-affiliated thinktank.
What does China say about non-CO2 emissions?
This is the first time that one of China’s NDC pledges has explicitly covered the emissions from non-CO2 GHGs.
However, while Xi’s speech made clear that China’s headline emissions goal for 2035 will cover non-CO2 gases, such as methane, nitrous oxide and F-gases, he did not give further details on whether the NDC would set specific targets for these emissions.
In China’s 2030 NDC, the country stated it would “step up the control of key non-CO2 GHG emissions”, including through new control policies, but did not include a quantitative emissions reduction target.
In preparation for a comprehensive greenhouse gas emissions target, China has issued action plans for methane, hydrofluorocarbons (HFCs, one type of F-gas) and nitrous oxide.
The nitrous oxide action plan, published earlier this month, called for emissions per unit of production for specific chemicals to decrease to a “world-leading level” by 2030, but did not set overarching limits.
Similarly, the overarching methane action plan, issued in late 2023, listed several key tasks for reducing emissions in the energy, agriculture and waste sectors, but lacked numerical targets for emissions reduction.
A subsequent rule change in December 2024 tightened waste gas requirements for coal mines. Under the new rules, Reuters reports, any coal mine that releases “emissions with methane content of 8 per cent or higher” must capture the gas, and either use or destroy it – down from a previous threshold of 30 per cent.
But analysts believe that the true challenge of coal-mine methane emissions may come from abandoned mines, which, one study found, have surged in the past 10 years and will likely overtake emissions from active coal mines to become the prime source of methane emissions in the coal sector.
As the demand for coal could be facing a “structural decline”, the number of abandoned mines is expected to grow significantly.
Meanwhile, the HFC plan did set quantitative targets. The country aims to lower HFC production by 2029 by 10 per cent from a 2024 baseline of 2GtCO2e, while consumption would also be reduced 10 per cent from a baseline of 0.9GtCO2e in this timeframe – in line with China’s obligations under the Kigali Amendment to the Montreal Protocol on ozone protection.
From 2026, China will “prohibit” the production of fridges and freezers using HFC refrigerants.
However, the action plan does not govern China’s exports of products that use HFCs – a significant source of emissions.
