Experts: What to expect in China’s climate pledge for 2035

The next round of “nationally determined contributions” (NDC) to the Paris Agreement, outlining countries’ climate goals to 2035, are due by February 2025.

They are also set to be an important agenda item at COP29 in Baku, Azerbaijan later this month.

China, as the world’s current largest emitter, has not yet confirmed when it will publish its next NDC. Its current NDC formalised the country’s “dual-carbon” targets of peaking emissions by 2030 and reaching carbon neutrality by 2060 – a pledge that has formed the cornerstone of China’s climate strategy since it was announced in 2020. 

Despite the country already achieving some of its existing NDC targets early, such as wind and solar capacity reaching 1,200 gigawatts (GW), it is not on track to meet others.

In addition, China’s recent stimulus package to “promote economic recovery” may lead to energy-intensive growth, exacerbating its “lagging behind” on current energy intensity and carbon-intensity targets.  

Several groups, including Climate Action Tracker, the International Energy Agency and the Centre for Research on Energy and Air, have set out what it would take to align China’s targets with the 1.5C limit or its existing national goals.

Below, Carbon Brief asks nine leading experts what they expect to see in China’s 2035 NDC. 

These are their responses, first as sample quotes, then, below, in full. They have been edited for clarity and length:

There was an agreement back at the time of Paris that countries would put their [NDC] proposals in early enough in the year, and this was actually our [the US’s] idea, so there would be enough time for the press, other countries, analysts to criticise [targets] – and countries, knowing that they would be criticised, would do their best. That was the theory. 

The new NDC targets are supposed to be put in February…It is going to be tremendously important that those [represent] a big step forward because…what happens in these upcoming targets is enormously important for the mid-century goals [net-zero emissions by 2050]…If the NDCs announced in 2025 to last until 2035 come up really short, if they’re effectively pretty weak, then you’ve just killed your chance to get anything done that you needed to get done by 2050 because you’re only 15 years away by 2035… 

[China is] the most important country in the world right now, with respect to their target. I think that other major players – the US, EU, Japan, Canada, Korea, Australia – are…going to put in pretty ambitious, pretty strong targets of the kind that you want to see. China now [accounts for] 30% of global emissions, and China is basically peaking [carbon emissions] about now…if not this year then next year. At 30% of emissions, people [at the Asia Society and elsewhere] have done analysis…basically saying that in order to be where we need to be we need to see something like a 30% reduction from China [by 2035]. I am sure [this] is certainly not what the Chinese are thinking of at the moment, but we’ll see how much of a chance there is to move. If the Chinese come in with a 5-10% target, it will be very bad.

I think it’s time for a mindset shift in designing the new NDC. So far, Chinese policy makers have taken a cautious approach, obviously constrained by the challenges in the domestic economy. But, in fact, stronger climate action and more ambitious targets are unmistakably an economic boon for China. 

The cleantech industry is emerging as a new economic driver in China, and companies are continuing to invest and expand their production capacity in anticipation of strong future demand. The conventional “under-promise, over-deliver” style of target-setting is not enough for the industry. 

An update of the renewable energy target is expected in China’s new NDC. A stronger target for the next 5-10 years will help expand the domestic market and give industry and investors the confidence they need. It will also lay the groundwork for an ambitious NDC, which will include an absolute emissions target for the first time, and its successful implementation.

However, China’s clean energy potential can only be fully realised with clearer plans to move away from fossil fuels. The continued expansion of the coal fleet is at odds with the historic development of renewables. The new NDC should address this contradiction by committing to no new coal power.

China’s past NDCs have tended to reflect trends underway, and highlighted concrete targets that are already on track to be met, rather than adopting ambitious new goals. The “dual-carbon” targets represented an exception – albeit a critically important one – where China saw a benefit to taking a global leadership position and going beyond existing domestic policy. 

A modest NDC would likely highlight targets related to renewable energy as a share of electricity production, continued steady growth in wind and solar capacity, and possibly electric vehicle adoption. Renewable capacity and electric vehicles are fields where China can showcase its success, scale and leadership without breaking new ground. China will almost certainly emphasise its steady roll-out of carbon trading to new sectors. 

At times of economic softness, China’s leaders may see little benefit to setting ambitious public targets for reducing carbon emissions, especially if they also perceive other countries backing away from aggressive initiatives. A major transition to decreasing carbon emissions is more likely to require testing and experimentation domestically, as a first step.

A reading of policy signals from the recent past suggest that China’s upcoming climate target is going to be conservative: coal plant approvals spiked in the years following a pledge to “strictly limit” coal power; official data showing that China is on track to miss its own 2025 carbon intensity targets; and the country’s top energy agency has proposed an annual installation target that would slow down clean-energy deployment. However, these developments contrast with the significant progress made in China’s energy transition, as the addition of renewable power capacity is on track to meet its annual increase in power demand.

The extent to which Beijing addresses this misalignment is both a climate policy decision and an economic one. The quest to find new growth drivers after the recent real estate slump is top priority for the government. How Beijing decides to rebalance its economy to drive growth, [and which] sectors it prioritises in the tried-and-tested approach to channel investment in infrastructure and manufacturing, will dictate China’s emission trajectory for years to come. Decisions that limit Beijing’s options – such as an emissions target that would constrain the sectors economic planners can leverage as drivers of growth, is likely to be a challenging argument to win in Zhongnanhai.

China is developing its 2035 NDC under exceptional circumstances. China’s economic slowdown, its 2035 targets being its first post-2030-peaking international commitment and the transition from intensity-based targets to absolute emission targets bring both tremendous challenges and opportunities for ambition. One Chinese expert I spoke to recently reflected: “I wish China’s NDC setting was as simple as pinning down a midpoint in a straight line.”

At least three variables will determine the quality of China’s headline commitment. The first is the quantum [the minimum amount] of emissions reduction. The second is the base year from which emissions will be reduced. The third is the sectoral and greenhouse gas coverage of China’s target. Depending on political will, Chinese decision-makers could plant ambiguities in any, none, or all these variables. Commitment could, therefore, be as vague as “by 2035, China’s emissions will have peaked and seen a steady decline”, or as clear as “by 2035, China’s greenhouse gas emissions covering all economic sectors will be reduced by X% based on Y year”.

Some experts believe that China will adopt its emissions peak as the base year for its 2035 target. For example, [they could say]: “By 2035, China emissions will be reduced by X% based on emissions peak.” This formulation could see China not specifying when and at what level its emissions will peak, extending the ambiguity in its updated 2030 NDC – to peak CO2 emission before 2030 – to 2035. If such a formulation is chosen, it will make the question of when, and based on what conditions, Beijing will confirm its emission peak ever more important. Currently, Beijing’s policymakers do not believe China’s emissions have peaked.

Citing poor baseline data, experts also believe that it is hard to expect gas-specific targets for non-CO2 gases in China’s upcoming NDC. This risks perpetuating a “chicken-and-egg” question, namely: should China wait until it has enough data to start cutting emissions, or should it impose reduction targets so as to accelerate better data gathering?

In order to align with 1.5C, China would need to increase the ambition of its 2030 NDC as well as putting forward a 1.5C aligned 2035 set of targets.  Alignment of a countries’ NDC with the Paris Agreement’s 1.5C goal was an agreed outcome of the global stocktake last year. 

In terms of total greenhouse gases emissions, excluding LULUCF (land use, land-use change and forestry), China’s emissions…reached a record high in 2023. According to CAT projections, emissions could peak before 2025, with the possibility that 2023 marked the peak. However, without additional commitments, emissions may rise again before 2030. Amid discussions on China setting a percentage reduction target from peak emission levels, CAT recommends basing the 2035 NDC on a historical baseline. The uncertainties surrounding peak emissions make it challenging to evaluate the level of ambition in future targets. 

China, like all countries, must also raise the ambition of its 2030 target. CAT’s modelled domestic pathways indicate that China needs to reduce emissions by 55% by 2030 and by 66% by 2035 from 2023 levels (excl. LULUCF) to align with the Paris Agreement. A minimum 28% reduction in total GHG emissions (excl. LULUCF) from 2023 levels by 2035 is crucial for China to stay on track for its 2060 domestic net-zero target, assuming a linear decline in emissions from the peak to 2060. 

China is on track to meet its previous NDC target of a 25% share of non-fossil fuels in total primary energy consumption by 2030: CAT’s modelled domestic pathways suggest that China should increase its non-fossil energy share to 73-84% by 2030 and 76-91% by 2035 to align with the Paris Agreement.

Regardless of its performance in various sectoral targets set in its current NDC, China is on track to fulfil its economy-wide overarching commitment of peaking CO2 emissions before 2030.

China’s new NDC is expected to reflect heightened domestic momentum for decarbonisation, as well as subnational and sector-specific initiatives, which have advanced the country’s specific climate targets beyond its initial international commitments, especially in renewable energy and electric vehicles (EVs).

The new NDC might also reflect ongoing domestic adjustments to the mitigation indicator system evaluating mitigation progress, such as by including a carbon budget system. This would be an encouraging move to address absolute carbon mitigation instead of the intensity target.

Incorporating mitigation measures for non-CO2 gas emissions could bridge the nation’s short-term CO2 peaking target for 2030 with its 2060 long-term carbon neutrality ambitions. China’s newly issued policies addressing methane and other non-CO2 emissions across agriculture, waste, and industry demonstrate China’s broadened climate strategy beyond CO2. This comprehensive approach enhances its ability to meet multi-gas mitigation goals, reinforcing the strength of its NDC as a commitment to tackling climate change across all greenhouse gases.

The new NDC would need to take into account the huge diversity of regional and subnational mitigation pathways and the desire to achieve a just-transition goal within China. Furthermore, international collaboration will have to balance the challenges posed by geopolitical shifts.

China is in the unique position of being able to single-handedly scupper the goals of the Paris Agreement, if it allows emissions to grow until just before 2030 and pursues slow and gradual emission reductions thereafter. In this scenario, China alone would use up almost the entire global carbon budget for 1.5C.

China’s emissions are stabilising at the moment, and if the rapid rate of clean energy additions is maintained, it will begin pushing the country’s emissions down.

However, recent policies and statements from China’s top policymakers show that they are still expecting emissions to keep rising until just before 2030 and to then fall very gradually. As long as the policymakers think in terms of a late 2020s peak, there is also little time to reduce emissions from that peak by 2035.

While China needs to reduce emissions by at least 30% from 2023 to 2035, and such reductions are achievable building on current positive trends, it seems more likely that the decision-makers will target a reduction that is a fraction of this, also falling short of the rate of reductions needed to get to carbon neutrality before 2060.

In addition to the 2035 headline target, updating 2030 targets is important. China is severely off track to some of the country’s key 2030 commitments…Reinforcing these targets in the new NDC is essential.

Since the target for wind and solar capacity was already, and entirely predictably, met, this leaves an obvious placeholder for a new target. Maintaining current rates of wind and solar additions would take total capacity to 3,000GW by 2030, and would align with the global goal of tripling renewable energy capacity. Current discussions reference numbers below 2,500GW, however, so it will be important to set an “at least” target or a range. [Such] expansionary targets…could also have more traction amid concerns about the economy.
There is a long list of other sectoral targets that could be included [to] shore up ambition, such as targets for [uptake of] EVs, rail freight and electric steelmaking and for the share of buildings retrofitted to meet energy efficiency standards.

A robust NDC is critical not only for achieving China’s climate goals but also for solidifying its role as a global leader in sustainability. While China has achieved notable progress, including advancing clean technologies and exceeding renewable energy targets ahead of schedule, challenges remain in reducing carbon intensity, transition away from coal, and fully meeting all NDC commitments.

Looking forward to the 2035 NDC, we hope China will consider setting clear and ambitious targets for total greenhouse gas emissions, including non-CO2 gases such as methane, alongside increasing the share of non-fossil fuels, and aligning with the Paris Agreement on the path to net-zero. In addition, sector-specific decarbonisation strategies, particularly for heavy industries, transportation and power generation, will be crucial to achieving meaningful emission reduction.

We also want to encourage stronger alignment between climate and biodiversity agendas by proposing the establishment of a climate and nature workstream within the UNFCCC/Paris Agreement negotiations, aligned with the Global Biodiversity Framework. This initiative could be advanced through the coordinated national plans required by both the climate and biodiversity conventions, fostering synergies between the two agendas. By integrating these efforts, the effectiveness of climate action can be enhanced while safeguarding ecosystems. We encourage China to initiate the discussion as the COP15 presidency.
