人工智能(AI)等技术的蓬勃发展带动了中国数据中心的“爆发式增长”,同时也推高了能源消耗和碳排放。
截至2023年底,中国以449个数据中心的数量位居亚太地区之首。
国际能源署(IEA)最新报告显示,2024年中国数据中心用电量已占全球数据中心用电总量的25%,成为仅次于美国的全球第二大电力消耗国。
与各国情况类似,中国数据中心用电量预计将在未来几年持续快速增长,人工智能的兴起是重要推动因素之一。
不过,当前实际需求规模及未来增速仍存在不确定性。
现阶段,其他驱动因素对电力需求增长的影响仍远大于数据中心。
虽然各方对数据中心的预测数据存在差异,但有报告指出,其电力需求可能从2025年的100-200TWh(太瓦时)激增至2030年的600TWh,相应的CO2排放量或将达到200MtCO2e(百万吨二氧化碳当量)。
尽管中央和地方政府已出台多项政策以应对数据中心的环境影响,但挑战依然存在。
电力需求不断增长
中国国务院援引官媒《中国日报》2021年的一份报道称,2020年中国数据中心耗电量达200TWh,约占当年全国总用电量的2.7%,预计到2030年将增至400TWh(占比3.7%)。政府最新数据显示,2022年数据中心用电量为77TWh,2025年预计为150-200TWh,2030年或达400TWh。
2025年初,彭博社援引高盛(Goldman Sachs)更高预估称,中国数据中心的电力需求“预计将增长两倍多(从目前的200TWh),到2030年可能接近600TWh”。

相比之下,国际能源署(IEA)的预测则更为保守,其预计2024年中国数据中心用电量仅为100TWh,到2027年可能翻倍。
无论从占全国电力需求的比重,还是作为需求增长的驱动力来看,数据中心的规模仍然有限。
不同机构的数据显示,当前中国数据中心用电量约占全国总用电量的0.9%至2.7%。
彭博社指出,数据中心的用电量“不到制造业的十分之一”,并提到仅2024年一年,工业用电需求就增加了300TWh。
国际能源署表示,自2022年以来,数据中心仅占新增电力需求的3%,到2027年这一比例可能升至6%。该机构认为,中国电力需求增长的主要推动力来自工业领域,包括工业电气化及供热和交通电气化。
不过,国务院发展研究中心资源与环境政策研究所副主任韩雪表示,到2025年底,数据中心相关的CO2排放量预计将占全国总排放量的1%。
建设“绿色数据中心”
2021年,中国宣布了一项为期三年的行动计划,旨在建设“高效、清洁、集约、循环”的“新型数据中心”。
该行动计划包括提高数据中心PUE(电能利用效率)的措施。PUE是衡量数据中心能源效率最常用的指标。
其计算方式是将数据中心总能耗除以IT设备能耗。该比值越高,表明数据中心的能效越低。
截至行动计划结束,全国数据中心平均PUE已从上年的1.54降至1.48。
2024年提出的新目标是到2025年将大型数据中心的PUE控制在1.25以下。相比之下,拥有欧洲最多数据中心的德国要求现有数据中心从2027年起平均PUE需达到1.5。
与此同时,中国于2022年启动了备受期待的“东数西算”国家工程,旨在处理东部人口稠密省份产生的数据。该项目鼓励在西部太阳能和风能资源丰富的地区建设新数据中心,以支持东部繁忙的大都市。
根据该工程规划,中西部地区的数据中心将处理更多非实时云计算需求,如离线分析和存储备份,而对时效性要求高的数据服务仍由东部地区提供。
内蒙古等北方地区的地方政府也出台了配套政策,推动数据中心与可再生能源设施协同建设。
此外,北京地方政府已为数据中心提供资金支持,用于改善其PUE。而南方科技中心广东省则选择将部分数据中心建在海底,以减少冷却需求并降低能耗。
自2020年起,中国政府持续跟踪数据中心能源转型进展。2024年最新数据显示,全国已有50余个数据中心达到“绿色”能源标准,其中国家电网1个、互联网企业14个。
面临可再生能源挑战
到2030年,中国数据中心预计将消耗400TWh至600TWh的电力,相关排放量可能达到200MtCO2e。
当前,中国可再生能源资源主要集中在北方地区,而电力需求仍集中在东南沿海。这意味着,即便有“东数西算”工程的支持,数据中心通常也依赖于长距离输电来使用可再生能源。
“绿色电力在数据中心行业应用前景广阔,但仍面临诸多挑战。”绿色和平气候与能源资深项目主任吕歆说。
她向Carbon Brief指出:“完成跨省绿色电力交易仍然非常困难。”她解释道,这主要受限于可再生能源发电的不稳定性以及长距离输电线路的高昂运维成本。
中国已出台相关政策,支持绿电直供数据中心,并建设了配备专用可再生能源和储能设施的“绿色电力产业园区”。
“这些政策的推进和市场机制的完善将促进数据中心使用绿电。”吕歆补充道。
另一项挑战是数据中心的用水需求。由于需要大量冷却用水,数据中心可能加剧西部和北部地区本就紧张的水资源压力。
为应对这一问题,北京、宁夏和甘肃等地政府已出台强制性措施,要求提升数据中心用水效率,并逐步淘汰电力和水效率低下的数据中心。
随着数据中心规模不断扩大以满足人工智能运算需求,未来可能出现更多耗电量达数千兆瓦的”超大规模”数据中心,这将带来更大的电力供应压力。在国家整体电力结构中,采用更清洁的燃料组合有助于减少排放。
但研究机构SemiAnalysis指出,由于中国对煤炭的依赖,当前中国数据中心“在排放方面处于明显劣势”。
目前煤炭在中国能源结构中占比约60.5%。国际能源署数据显示,中国大部分数据中心所在的东部地区,约70%电力来自煤电。不过该机构预测,2030年后可再生能源与核能的快速发展将“推动煤炭的退出”。
该报告预计,到2035年,可再生能源和核能将“共同满足中国数据中心60%的电力供应”。

Bonn Bulletin: Tackling climate crisis is “hardest” challenge ever, Stiell says
Kicking off proceedings at the mid-year climate talks in Bonn amid fraught global geopolitics, UN climate chief Simon Stiell told delegates that tackling the global climate crisis is “the hardest, but most important, thing humanity has ever tried to do together”.
Perhaps hoping to forestall the usual diplomatic wrangling that routinely bogs down the talks, he warned governments that there is no time to “re-open past debates or renegotiate commitments already made”.
Instead, he added, there is an imperative to accelerate real-world action as deadly heat intensifies and the fossil-fuel cost crisis sparked by the Iran war strangles economies, “taking a wrecking ball to lives and prosperity”.
That message seemed to sink in with the negotiators in Bonn, where the opening session kicked off only an hour late and was not marred by agenda rows, which delayed the start of the talks by a day last year.
On bridging the gap between the negotiations and the real economy, Stiell called for elevating the Global Climate Action Agenda, a goal long promised but never fully delivered.
But, he added, Türkiye – working with Australia – is now building on the efforts by last year’s COP30 presidency to streamline this process into six thematic areas, including boosting energy and food security, curbing methane and strengthening the resilience of cities.
Stiell was also keen to stress that the formal negotiations remain central to driving implementation of the Paris Agreement. He urged governments in Bonn to advance key issues including the Global Goal on Adaptation, the delivery of the outcomes of the first Global Stocktake and the development of a new just transition mechanism.
The first Global Stocktake was an assessment of countries’ collective progress in meeting the goals of the Paris Agreement, which led to a 2023 agreement to transition away from fossil fuels in energy systems and a 2030 goal to triple renewable energy, among other things.
Hinting at upcoming reforms to the UN climate regime – which has often been accused of failing to keep pace with advancements in the real world – Stiell said all institutions must continuously evolve and improve. The UN climate secretariat has heard countries’ calls to work more efficiently, support access to climate finance and reduce the reporting burden on governments, he added.
Türkiye to outline targets for Action Agenda
While Australia will run the negotiations at COP31, for co-host Türkiye – which is organising the talks in Antalya – the focus is on the so-called Global Climate Action Agenda. This is a sprawling smorgasbord of around 500 voluntary initiatives bringing together governments, businesses, investors, cities and civil society. It covers everything from strengthening power grids for clean energy, to restoring degraded forests and land, and reducing emissions from buildings.
COP31 President-Designate Murat Kurum told the opening session of the Bonn talks his team will present the “main framework” of the Action Agenda on Tuesday, adding it will be “based on concrete and tangible targets”. He also said Türkiye will announce a roadmap for translating what happens in the negotiations into the real world, which will ”point to a science-based process with highly clear and defined outcomes” and steps for getting there.
“In the second decade of the Paris Agreement, the COP31 Action Agenda will bring the outcomes of the first Global Stocktake to life, and we will make a strong start to the second decade,” Kurum said.
In a joint letter issued in May, the two host nations said COP31 will be shaped as an “Implementation COP” and a “COP of the Future,” aimed at translating commitments into tangible and trackable progress. They outlined priority areas – to be achieved through the six axes of the Action Agenda defined ahead of COP30 – including electrification, zero waste, resilient cities, sustainable agriculture, green industrial transformation and climate finance.
Chiming with this, Australia’s Chris Bowen, the COP31 president of negotiations, made the global energy transition the centerpiece of his opening intervention in Bonn.
This year’s climate summit, he said, must send investors and corporations the message that countries are “collectively committed” to building up renewable energy and reducing fossil fuel reliance. Fossil fuels were not directly mentioned in the main outcome at COP30 last year after countries failed to agree on developing a global transition roadmap, which Brazil is now putting together outside of formal negotiations.
Bowen, Australia’s minister of climate change and energy, said that, while energy crises like the one the world is going through now will become more frequent and more unpredictable, accelerating the shift to cleaner sources will “ease shocks to our energy systems”.
He identified progress on electrification as a priority for COP31, pointing to an assessment by the International Energy Agency (IEA) that electricity’s share of final energy consumption needs to reach 35% by 2035 to keep the 1.5C temperature goal in sight.
“In a world of geopolitical uncertainty and energy disruption, the transition is not a risk,” Bowen added, “it is the solution and an immense opportunity”.


Tensions around trade and climate surface again
Over the weekend, it became clear that discussions on trade and climate would once again become a source of contention between countries – if not as explosively as they did at the start of the talks a year ago.
As agreed in the COP30 Global Mutirão decision, a series of dialogues on trade and climate will be held in Bonn yearly from 2026 to 2028. Climate Home News understands that the G77 + China has expressed discontent about the organisation of the first dialogue that will take place on June 13, because it plans to incorporate contributions from a range of organisations rather than just governments.
In a statement at the opening plenary, Uruguay, on behalf of the G77 group of developing nations, “encouraged Parties [countries] to engage constructively in the dialogue in a robust and structured manner”. Many in the Global South are concerned that international trade measures to make products greener, such as the European Union’s carbon levy on imports, could end up discriminating against them.
Russia warned during its opening statement that the new dialogue should not be used to create trade barriers.
Comment: Indonesia’s failing Just Energy Transition Partnership is a cautionary tale
Avantika Goswami, climate change and green economy programme manager at the India-based Centre for Science and Environment, told Climate Home News that the UN climate secretariat has been unclear and untransparent about what will be discussed at the dialogue. “We don’t know if observers and civil society are going to be able to contribute,” she added.
After the three mid-year dialogues, in 2028 there will be a high-level event for countries to exchange their views and experiences, and the officials in charge will have to present a report summarising these discussions.
At Monday’s opening session, Antwi-Boasiako Amoah, the Ghanian chair of the African Group of Negotiators, said it would be “important to provide clarity on how they intend to present the report” and suggested that the co-chairs of the Bonn talks should consult with countries on how best to do that.

Bowen urged to lead with vision and ambition to accelerate fossil fuel phase out at Bonn climate meeting, as global energy crisis bites
Bonn, Germany, Monday 8 June 2026 — As the UN climate negotiations in Bonn commence, Greenpeace Australia Pacific is calling on Climate and Energy Minister Chris Bowen to lead with vision and ambition to advance multilateral climate cooperation, and use his unique position to drive concrete progress at COP31 and ensure a meaningful partnership with the Pacific.
In the context of a global energy crisis and turbulent geopolitics, the Bonn Climate Change Conference will be a critical moment to sustain emerging political momentum towards a just transition away from fossil fuels. The midway point on the road to COP31 in Türkiye in November, Bonn will be the first time Minister Bowen has attended a major UN conference in his role as COP31 President of Negotiations.
The start of the Bonn meetings also marks 100 days since the illegal US-Israel war on Iran sparked a global energy shock and after 57 countries including Australia met in Santa Marta, Colombia in April for the world’s first conference on the transition away from fossil fuels — a landmark moment signalling political winds of change in the face of threats to multilateralism.
Speaking from Bonn, Dr Simon Bradshaw, COP31 Lead at Greenpeace Australia Pacific, said: “Amidst a global energy crisis, accelerating climate disasters and a looming super El Niño, the urgency to accelerate climate action and break free from fossil fuel dependence has never been clearer.
“Minister Bowen has been telling Australia and the world that we are in a global ‘fossil fuel crisis’, and that unhooking from fossil fuels is fundamental both to tackling the climate crisis and to ensuring secure and affordable energy. It’s time to match that message with a clear vision and agenda for COP31 — one that has the transition away from fossil fuels at its heart.
“As COP31 President of Negotiations, Australia has both the opportunity and responsibility to build on the momentum of COP30 in Belém and the recent landmark conference in Santa Marta on transitioning away from fossil fuels. This includes leading by example at home, with an immediate halt to new fossil fuel projects — including the mammoth proposed Browse gas project — and committing to develop a national roadmap away from fossil fuel production.”
“Few countries have as much skin the game as Australia: we are a country highly vulnerable to extreme heat, fires, floods and other impacts of climate change, we are suffering the consequences of fossil fuel dependency in terms of our energy security and affordability, but we have some of the world’s best renewable energy opportunities.
“Bonn is a key moment for the incoming Presidency to start shaping the vision, building the necessary trust, and actively setting priorities and expectations for the COP. We therefore hope and expect our Minister to be much more vocal and active in Bonn.
“Australia, in partnership with the Pacific, is taking the reins of global climate cooperation at a critical moment in the world’s transition away from fossil fuels. There is no more time to lose.”
Also in Bonn, Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific, said: “Multilateral cooperation is the antidote to climate and geopolitical chaos. At Bonn, Pacific nations’ legacy of leadership from the frontlines of the climate crisis can be our guiding star as we build a more peaceful and secure world for all.
“We must build on the progress at Santa Marta and break the hold fossil fuels have on our global security and economies. Pacific nations are already facing the brunt of a global climate crisis, but now facing the compounding injustice of an energy crisis brought on by fossil fuel dependence. We did not create either of these crises, but are among the most exposed to both.
“The International Court of Justice made clear that responsibility to address the climate crisis extends beyond borders and that continuing to expand fossil fuel production, including for export, could constitute an internationally wrongful act — a ruling that has now been overwhelmingly endorsed by the UN General Assembly. Continuing down the fossil fuel path, and failing to align efforts with limiting warming to 1.5C, is a breach of our international legal obligations.
“We must not lose sight of what’s needed — by elevating the voices of Pacific leaders, backing Pacific-led solutions, and maximising the opportunity of the Pacific pre-COP, we can ensure the 1.5°C imperative and the transition away from fossil fuels are central to the agenda at COP31, and that communities are granted the finance they need to build a strong, resilient future beyond fossil fuels.”
Ahead of SB64, Greenpeace International has produced a policy briefing outlining the core elements of a just transition away from fossil fuels and the urgent, priority actions needed from national governments and through global co-operation to make it a reality.[1]
