She was the chair of the Science Advisory Council of the UK’s Department for Environment, Food and Rural Affairs (Defra) and has previously served as chief scientific adviser to the Scottish Government for Rural Affairs, Food and Environment. She is a leading hydrochemist.
On funding climate research: “You can’t look at climate research just as climate research. It’s a nexus. It’s thinking about climate change, the implications for biodiversity loss and other changes like pollution.”
On funding solar geoengineering: “A few years ago, I think this council and many others would not have gone into solar geoengineering in any sense. We’re getting closer and closer to 2050. That starts you looking for more extreme routes.”
On Brexit’s impact on UK research: “I think that led to some breakage of communication and links with people working in Europe particularly.”
Carbon Brief: You have a long standing career as a hydrologist and a pollution expert, when did you first become aware that humans were having a large impact on the natural world through pollution and agriculture?
Prof Louise Heathwaite: Before I went to university – well before I went to university. At school I studied maths, economics and geography and put it together in that sort of sense. Then I went on to do an environmental science degree at the University of East Anglia. At that point, there were only two places you could do environmental science, UEA or Lancaster. Lancaster was far too close to home for me [Heathwaite is from Leeds]. UEA were doing some really cutting edge science. That’s when the ozone hole was just being discussed. So I knew from a long, long time ago that we were doing damage. So it’s been with me all that time. And that progression with working with the Natural Environment Research Council started at that point. I went from doing a degree to doing a PhD at Bristol and that was funded by NERC.
LH: I was looking at peatlands, wetland hydrology and hydrochemistry. I was looking at the impact of [peatland] drainage on water quality. The place I was working was the first SSSI [site of special scientific interest] ever declared in the country. It was a place called West Sedgemoor in the Somerset Levels. It was a real interesting challenge there, looking at the difference between what the [wildlife charity] RSPB wanted to do to protect that site versus the farming community, who wanted to actually farm that site, and how you get some sort of shared understanding. It was really fascinating. And underneath that there were some real chemistry questions to answer as to why the river was getting polluted and what the issues were. And it wasn’t anything to do with the farming community at all. It was to do with the geology of the site. Really interesting.
CB: This year, you became the executive chair of NERC. What are the key areas of climate research that NERC is looking to fund?
My perspective is you can’t look at climate research just as climate research. I think there are three parts to this, it’s a nexus. It’s thinking about climate change, the implications for biodiversity loss and other changes like pollution. So I always argue you’ve got to think of it through that three-way nexus. The direction of travel I’m trying to take NERC through in terms of our forward look is developing thinking that I’m starting to call “beyond carbon”. So when you talk to communities like the financial industry, what they’re looking for when they want to understand biodiversity loss is another metric, like carbon, that can tell them how to deal with the problems. [We need to] get to the realisation that, for biodiversity loss, there is no single metric. And a lot of what the climate change drivers are doing are causing feedback loops, which damage biodiversity, create other sorts of challenges, and how do we understand that? So there’s a whole load of work to do in that sort of space. So that’s one bit where climate change is a real driver. The other bit is around national security and health. Your floods, your droughts, risk for wildfires, risk for temperature and heat and what that does to people. That’s another area.
Then the third area you might think will be quite unusual for NERC, which is starting to look at what we’re calling “responsible innovation”. So NERC has just got a call out around solar radiation management. Now, a few years ago, I think this council and many others would not have gone into solar geoengineering in any sense. But the position we’re getting into now is we’re getting closer and closer to 2030 and to 2050 and trying to get to things like net-zero. That starts you looking for more extreme routes. I think it’s important that a research council tries to understand what the implications are of anybody following those extreme routes. I need to be clear, we’re not doing out-of-door experiments, it’s more around modelling and maybe some laboratory work to try and understand that. But if we don’t understand solar radiation management, or we don’t understand the sort of interventions you might do in the oceans, then we’re not going to be able to advise on the implications. And, with the Natural Environment Research Council, we’ve got everything at our fingertips, really, because we do deep ocean to upper atmosphere. We do pole to pole. We do air, land, water. And that captures the global capacity. And so actually addressing those climate change challenges sits right in our remit, at a very difficult time, really.
CB: How has NERC research funding been impacted by Brexit? Does NERC have all the resources it needs at the moment?
Brexit or everything else after Brexit? We’ve had Brexit, then we have Covid, and then we had Ukraine and inflation and all of those things. From a Brexit context, and this is a personal view, I think that led to some breakage of communication and links with people working in Europe particularly. Now we’re part of Horizon again [the EU’s €96bn research programme], I can see that coming back, which is absolutely fantastic, it’s really important. I think also within NERC, all of those issues that I just mentioned have also led us to perhaps start looking [at] more UK-wide, rather than global and international science. That’s something I want to change. That international science is absolutely critical, particularly as we’ve got many of our scientists working with the IPCC [Intergovernmental Panel on Climate Change] and IPBES [Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services]. And we’ve got the new UN Environment Programme around pollution and waste. So those three areas I mentioned before, we’ve now got intergovernmental panels which are actually looking at them. I think of our opportunity as to how we bring them together and think about it as a system.
CB: You recently stood down as the chair of the Science Advisory Council for Defra. What did it entail, how often were you briefing ministers and what kind of information were you sharing with them?
LH: So this was the highest level advisory committee within Defra, but part of our role was very particularly to help support and advise the chief scientific adviser [CSA], so that they were getting the best sort of advice. So the way that that worked was to basically take challenges from across Defra and [answer questions such as] are we doing this right? What’s your advice? How could we do this sort of thing? And get that [answered] by a wide range of people on the committee. [This was] to actually ensure two things: that the right sort of questions were being asked of the science and the right sort of evidence was being gathered, and that evidence was being used effectively. So the route was really to make sure that the CSA had a group of “critical friends”, in a sense, but also was [well] informed. Briefing ministers was the CSA’s job. Acting as a science advisory committee [and] actually making sure that the CSA and others in Defra were actually being coherent in their messages around the science – it was fascinating. But I’d been on Defra’s Science Advisory Council before, so that was really exciting. I’ve been a chief scientific adviser in the Scottish Government for Rural Affairs, food and environment before, so that fitted really well with that role. But it’s an important entity providing that sort of independent advice, that critical friend bit, is always important.
CB: Farming and land use have been a weak spot in UK climate plans, and now agriculture is a bigger emitter than power plants, for example. What do you think is needed to help the farming sector get to net-zero?
LH: I guess let’s start with the end point, getting to net-zero by 2050. It’s going to be a challenge to ever get to [actual] zero [emissions]. And what does getting to the “net” in net-zero mean? We need to have that national security of still being able to turn the lights on. I think that’s important. By setting targets and target dates, this is the bit I mentioned about geoengineering, it tends to get more and more desperate measures because you’ve got a target. I tend to think of it more as a transition. How do we transition, both in terms of behaviours, but also in terms of the science and the interventions we can put in to actually get to those sorts of places? So that seems to me to be really, really important and how we actually capture that moving forward is critical.
LH: That is always going to be a challenge because you’ve got two things. One, I think we need to look at farming and the farming community and landowners as being part of the solution, not the problem. Think of them as custodians of land and of the environment. Therefore, you start having a different conversation, which isn’t, “this is wrong, having cows and sheep is wrong”. But: “How do we actually get to a better place where we can have a shared understanding of what the environment’s about? What alternative livelihoods do people have?” Even down to evaluating whether we pay the right sort of amount for the meat we want to eat. So if people were prepared to pay more but eat less of it, that might actually change the economics of how farming might work. But none of that works if you go to the supermarket and buy something that’s been shipped in from some other country, either. So I think it’s a conversation, a shared conversation, about what the vision is for the future. And I think, so far, that vision hasn’t been much beyond “we’re going to plant trees everywhere, and cows are bad”. You’ve got to turn it into “we’ve got a fabulous landscape, we’ve got a very dense population, we want to do all these other things with our land, how can we actually have a conversation to get us to the right place?” And that’s not going to be easy, but what I’m seeing is now much more cross-government thinking about how to get there.
If you actually mapped out all the policies that we want to achieve from our land, we haven’t got enough area, nowhere near enough area, to actually achieve them. So we’ve got to think about the nature of the interventions and what we achieve. It’s a really exciting space. From my perspective, coming from where I came from as a scientist, understanding how those changes might impact on other parts of the system. So like the freshwater environment, which is always the bucket in which all the problems end, and then we pass that on to the marine environment, and we pass it up to the atmospheric environment, how can we actually get a more sustainable solution there? So it’s an opportunity, But if you turn it into a problem, all you do is back people into a corner.
CB: The new Labour government has come in, and it has a lot on its in-tray when it comes to food, land in nature, including a land-use framework and its international nature pledge under the UN biodiversity convention. Which of these documents would you like to see being published soon, and what sort of details do you think will be critical for those documents?
LH: Big question, massive question. I’ll probably answer this a bit tangentially because it’s really a matter of how you can achieve what you can achieve. This government has got a very strong focus on delivery for people quickly. And there are some quite exciting and quite interesting projects around clean energy by 2030, as an example. So what does that mean for things like land use that we’ve just been talking about, biodiversity and all of those things? Is it a really good pledge, but the ones around the land-use strategy are really, really challenging. Because, say, clean energy for 2030, if we can make that work, we’ll need to make sure we get the transition mechanisms in place to move energy around from generation points to to where it actually needs to be delivered. If we can do that for energy, we can probably do that for land. So we do need it, but it’s hard to see who’s going to really have the oversight. And everybody wants a piece of this pie. But all the things that this new government is wanting can’t be achieved without some joined-up thinking. So I put that quite high.
I also think making clear our commitment to work in the international space [is important]. My council, the National Environmental Research Council, is the one that thinks at long timescales, large scales, global. So actually having that international presence and keeping our science cutting edge and curiosity driven is just so important in that sort of space. So I’d be articulating that through the new government that the research and innovation part is really, really critical, because that’s where you’ve actually got that curiosity driving new thinking, but you’ve also got the innovation which takes that new thinking and now converts it into something useful. Some of it’s shovel-ready now, but actually, some of it’s going to take time to actually get us there.
CB: So, finally, we touched on this before, but the issues of pollution and biodiversity loss tend to receive less attention at a national and international level than climate change. Why do you think that is and how can that be addressed?
LH: I think it’s only that climate change has been thought of as being doable – because it’s carbon, and we’ve got that single metric – and therefore business and industry can buy into that and they can think about how to build it into their business models. The reason I think pollution and biodiversity loss are lagging behind is it’s much more complex to understand that system and we’re only getting together now with the science to actually help us do that and develop those metrics. But there is no single metric to say we can understand biodiversity loss. It’s going to take some more systematic thinking. And one of the really good things I think about where NERC is now placed within UKRI [UK Research and Innovation, a government department] is that we’ve got that cross-research council thinking, which allows you to pull from all the various disciplines to get a solution.
China has released its “15th five-year plan for the development of renewable energy”, outlining key targets and policies for the sector in 2026-2030.
A key focus of the plan is boosting renewable generation and consumption as a share of China’s overall energy mix.
It calls for continued capacity additions of wind and solar – albeit at lower levels than previous years – as well as hydropower, biomass and other clean-energy sources.
Specifically, China will aim to install 3,500 gigawatts (GW) of renewables capacity by 2030, 2,800GW will be wind and solar.
The country had previously pledged to install 1,200GW of wind and solar by 2030, a goal that China met six years early.
Another major theme is the provision of wind and solar supply that is “dependable” and “grid-friendly”.
Setting a target for “dependable output” from wind and solar could help to entrench their role as a provider of “energy security”, according to analysts.
The government also aims to boost renewables consumption by developing non-power uses of renewable energy, in sectors such as steel and chemicals.
Below, Carbon Brief examines the key targets and policies outlined in the five-year plan and what they mean for China’s energy transition.
Five-year plans are key to China’s political system. An overarching plan, covering all socioeconomic issues of importance to policy leaders, is published at the beginning of each five-year cycle.
The plan for the 15th five-year period (2026-2030) was published in March 2026.
It includes what the government considers to be the most important targets and policy signals for climate and energy. For example, binding targets for carbon intensity, the share of non-fossil energy in total energy consumption and total energy production capacity.
Following this overarching document, five-year plans focused on specific sectors or themes are then published over the course of the five-year plan period.
This year, the government has already published several five-year plans related to energy and climate change. One covers the development of the “new-type” energy sector more broadly. Another wraps climate goals together with other environmental targets under the “Beautiful China” programme.
By contrast, the renewables five-year plan focuses specifically on the development of hydropower, wind, solar, biomass, geothermal and wave energy.
It covers topics including capacity and generation targets, as well as efforts to increase integration and reliability of wind and solar. It also has policies to encourage “non-power use” of renewable energy and ways to strengthen innovation of clean-energy technologies.
What overarching renewables targets are in the plan?
China will aim to install 3,500 gigawatts (GW) of renewables capacity by 2030, according to the five-year plan.
Of this, 2,800GW will be wind and solar – a pledge reiterated from China’s action plan for peaking carbon emissions, which was released earlier this month.
The goal more than doubles a previous 2030 target for wind and solar to reach 1,200GW, which China met six years early.
As of June 2026, the country has installed just under 2,000GW of wind and solar capacity, as well as 454GW of hydropower. Biomass, geothermal and wave energy hold very small shares of the overall energy mix.
As such, China would need to build 160GW of wind and solar each year – and just under 220GW of renewable capacity in total – to meet the targets.
The country installed 277GW of new solar alone in 2024 – and 315GW in 2025.

A key part of meeting the targets will be the development of large-scale clean-energy bases in China’s northern regions. These will generate power to be exported elsewhere via ultra-high voltage lines. The plan also encourages greater “local consumption” and installations of distributed energy (see below).
The plan says that further research will be directed at increasing the renewable share of electricity generated by these large-scale energy bases to 100%.
A recent report by the thinktank Global Energy Monitor (GEM) finds that output from these bases “continues to be paired with coal-fired generation in the name of balancing and system flexibility”. It says that currently, coal generates 42% of the power transmitted to the rest of the country from these bases.
China will also add more hydropower, says the plan, with capacity rising from 448GW in 2025 to 570GW in 2030. Some 160GW of this will be pumped-storage hydropower.
Meanwhile, the plan sets a target for renewable power generation to reach 6,000 terawatt-hours (TWh), 4,000TWh of which would come from wind and solar.
This would be a 50% increase in five years as renewables generated just under 4,000TWh of electricity in 2025, according to the National Energy Administration.
By 2030, the plan says that total consumption of renewable energy will stand at 1.8bn tonnes of coal equivalent (Gtce).
This would be up from 1.2Gtce in 2025, which represented about one-fifth of China’s total energy consumption of 6.2Gtce that year.
The renewable targets in the plan are lower than those suggested in a recent study by high-profile Chinese scholars.
The study, from the department of energy and power engineering and the Institute of Climate Change and Sustainable Development at Tsinghua University in Beijing, assessed the “likelihood of China attaining its carbon peak” under different pathways.
It found that, in order to meet its climate commitments, China would need to either install more than 4,000GW of “non-fossil energy capacity” before 2030, or to “maintain a total energy consumption” below 6.5Gtce.
The table below outlines some of the key renewables targets for 2030, as specified in the plan.

Why does the plan focus on ‘firm capacity’ for renewables?
As well as increasing the overall size of China’s renewable power supply, the country must also maintain an “uninterrupted and reliable power supply”, officials from the NDRC and NEA told state news agency Xinhua in coverage of the new plan.
To support this goal, the plan says that the development of renewables will “enter a new stage”. This will mean that “improving quality and serving as a reliable alternative” to fossil fuels will be as important as “expanding scale”.
The plan, therefore, proposes targets for the “firm capacity” from wind and solar (置信出力). This is the amount plants or grids can be relied on to produce during critical supply periods, in conjunction with on-site storage.
The target for wind is a firm capacity of at least 11% of total installed capacity by 2030, while the equivalent goal for solar is 6%.
Wind and solar will also be expected to supply more than 20% of total demand in peak periods during the summer and winter evenings, says the plan. It expects “reliable peak-shaving capacity from renewable sources” to reach more than 300GW.
The new targets are a “positive move”, says Yao Zhe, global policy advisor at Greenpeace East Asia, as it “only applies during peak load and critical supply periods, when coal power is typically used to stabilise the power supply”.
She adds that this could, theoretically, “prevent the construction of new coal-fired power projects that are proposed and approved for the reason of meeting peak demand”.
The new metrics mark a change in focus, says Lyu Wenbin, director general of the Energy Research Institute – a state thinktank under the NDRC – in an “explanatory reading” posted on BJX News. He says it “marks a shift in renewable energy development from the mere pursuit of installed capacity to…also taking into account system support capabilities”.
The plan pledges to “accelerate the construction of grid-friendly wind and solar power stations”. It says this will enhance “reliable peak-load generation” and strengthen renewables’ ability to ensure “safe and stable operation” of the grid.
It says this will particularly be a focus in the energy-hungry east, central and south areas of China.
It sets out a slightly different focus for areas that already have a high share of renewables in their power mix, such as north-west China. Here, the aim will be to develop wind and solar parks that are “capable of providing voltage, frequency and inertia support”.
“This is a real challenge”, says James Norman, research analyst at GEM. He says these challenges are particularly acute in some circumstances:
“[For example], when the share of wind and solar is very high, relatively few synchronous generators (like coal) are online or large volumes of electricity are being transferred through high voltage DC lines.”
The plan mentions many technological solutions to address the problem, he tells Carbon Brief. However, he adds, there are no quantitative details for the issue. For example, he notes there is no target for “how many gigawatts of wind and solar must gain grid-forming capability”. This is in contrast to the goals for overall renewables capacity or generation.
Norman was a co-author on the recent GEM report, which identified further barriers to renewable uptake. It said these include transmission bottlenecks, alongside systemic features such as dispatching and power-contract mechanisms.
As a result, said the report, renewable power – especially solar – is increasingly being “curtailed”, particularly in north-western and northern provinces.
Yao also notes that the plan does not “spell out specific measures to address systemic constraints” around the electricity grid and the role of coal in the power sector.
“I interpret this as evidence that the vested interests are still strong in the policy debate,” she adds.
What does the plan say about ‘distributed’ energy?
Alongside gigawatt-scale clean-energy megabases, China also aims to expand construction of “distributed” energy. This means smaller-scale installations, such as rooftop solar.
More than 300GW of “distributed new energy” is to be added over 2026-30, some 60GW per year.
The plan aims for distributed new energy to be adopted in sectors such as industry, transport, buildings and agriculture.
Applications include the use of distributed solar and wind in industrial parks, coal mines and oilfields, as well as encouraging residents to install solar panels on buildings and developing rural clean-energy grids.
In some regions, distributed solar and wind is “likely to meet a large proportion of local demand”, says Prof Pan Jiahua at the Hong Kong University of Science and Technology (Guangzhou). He tells Carbon Brief that micro- and mini-grids using such resources will be particularly important in central and coastal China.
The 60GW annual target for new distributed energy is not “overly ambitious”, says Isadora Wang, head of China at the thinktank Transition Asia. She tells Carbon Brief that distributed solar additions, alone, exceeded 100GW in both 2024 and 2025.
Cosimo Ries, analyst at the consultancy Trivium China, agrees that the target is reachable. The biggest question mark, he tells Carbon Brief, is whether it will continue to make sense for industry and utilities to build distributed power at the volumes seen during the 14th five-year plan period.
He adds that market conditions for distributed solar have deteriorated sharply over the past two years. He says a range of factors have hit investor confidence:
“[Distributed solar faces] growing exposure to market trading, worsening returns in spot markets, growing risks of curtailment and new policies limiting or forbidding the selling of power back to the grid.”
What does the plan say about non-electricity use of renewables?
The plan also sets goals for renewable energy’s role in “non-electricity use”.
This means using renewable energy for purposes other than generating electricity, through converting it to other forms, such as heat or mechanical energy.
The government is aiming for non-power use to nearly triple from 60m tonnes of coal equivalent (Mtce) in 2025 to 150Mtce in 2030.
Ries tells Carbon Brief that he thinks this target is “one of the main highlights” of the plan. However, he notes that limited available data means it is hard to assess the level of its ambition. He adds that, given the relative conservatism of China’s other recent clean-energy targets, this one may also be met relatively easily.
Key applications for non-power use of renewables include “green hydrogen, ammonia and methanol”, says the plan. It also points to using wind and solar for heat, as well as to biomass and geothermal for heating and cooling.
Green hydrogen, ammonia and methanol are the “centrepiece” of the non-power push, according to state-owned newspaper Economic Information Daily.
For hydrogen alone, China plans to scale up renewable hydrogen production to 2m tonnes in 2030, up from 250,000 tonnes in 2025.
Today, non-power use of renewables accounts for only around 1% of China’s total energy consumption, NEA and NDRC officials said in a Q&A. They added that there is “considerable room for growth” in sectors such as industry, transport and buildings.
Potential new applications include the use of wind and solar for heat. This could see the use of centralised wind and solar heating stations in the chemicals, textiles, pharmaceuticals, papermaking and food sectors.
New projects in the steel and cement sectors should use locally-generated wind and solar to power electric-arc furnaces and kilns, adds the plan.
Wang tells Carbon Brief that she believes the naming of individual sectors is a “clear indication” that they will be included in China’s renewable consumption quotas. These already cover aluminium and other heavy industry sectors.
She adds that power and heat demand from the named sectors may help absorb distributed renewable energy. It will also serve as a testing ground for matching demand with supply through increased grid flexibility and power price reforms.
To Ries, the growing focus on non-power use signals that China’s decarbonisation efforts are “now entering deeper waters”. That means regulators are turning from easier-to-abate sectors, such as aluminium, to more challenging industries, such as steel.
The plan could create a “second growth curve” for the new-energy industry, says He Zhao, in a commentary for China Power News Net. He, the vice-president of the China Electric Power Planning and Engineering Institute (EPPEI). says this might begin with non-power use, before shifting to fuel, feedstock and heat substitution.
What does the plan say about China’s cleantech dominance?
The next five years is a prime opportunity for China to “consolidate our leading position across the entire industrial chain” for clean-energy technologies, says the plan.
It adds that the government will “strengthen technological innovation” and accelerate the roll-out of new applications of artificial intelligence in China’s renewable-energy system.
A particular focus for new R&D will be “cutting-edge, original and disruptive technologies”. It also points to technologies that “enhance the reliability of renewable energy” as a substitute for fossil fuels.
The plan names technologies for further development. For wind power, these include “reliable and low-cost” blades, ultra-tall towers and new types of floating platforms. It also mentions the development of “high-altitude wind power”. For solar, it points to the development of perovskite and other “high efficiency” solar cells, as well as space-solar technologies.
The plan also pledges to develop a power market that supports the “full entry” of renewable-energy companies. It underscores that companies should plan for an increasingly market-based and competitive environment.
Meanwhile, the government will also deepen cooperation with other countries on clean energy and “advance” global climate cooperation, it says.
A priority will be “strengthening” international coordination on investment and development in “green energy projects”. Another is “actively promoting the free circulation of China’s high-quality green technologies and products in global markets”.
Chinese exports of clean-energy technologies have been surging, especially since the closure of the strait of Hormuz.
At the same time, Chinese investment in clean-energy projects in Belt and Road Initiative member states totalled $20bn in the first half of 2026. This is also driven by the crisis.
The US, EU and others have launched tariffs and pricing mechanisms to curb imports of Chinese cleantech. This has contributed to pushback from China, against what it and others refer to as “unilateral trade measures”.
China is transitioning from a “major energy nation” (能源大国) to an “energy powerhouse” (能源强国), writes the Energy Research Institute’s Lyu in his explanatory reading. He says this will enable China to increasingly shift to building “systemic” advantages in developing clean-energy technologies.
He continues that, from 2026-2030, China will “move to the very forefront of the global stage” on clean energy, “venturing into uncharted territory”. This will create both “major new challenges and significant opportunities” for the country, he adds.
Interview: Dr Sun Yixian on his new database tracking Chinese climate ‘leadership’
SYDNEY/KINGSTON, Wednesday 29 July — The future of deep sea mining will be a focus for world leaders this week as the International Seabed Authority (ISA) Assembly takes place in Kingston, Jamaica.
Country delegates and members from Pacific Civil Society have come together to discuss a deep sea mining code, while the call for a moratorium grows. It follows the ISA’s contentious decision last week to extend The Metals Company subsidiary Nauru Ocean Resources Inc’s (NORI) exploration contract, despite its support for the pursuit of unlawful deep sea mining via US unilateralism.
The Assembly’s agenda was agreed to yesterday, with a science item put forward by Vanuatu to be heard on Thursday local time. Overnight, Mozambique and Mauritius joined the call for a global moratorium.
Rae Bainteiti, Pacific Political Coordinator at Greenpeace Australia Pacific, said from the ISA in Kingston:
“As we move into the General Assembly this week, the fundamental issue remains that there is not enough science to guarantee the safety and protection of the ocean in a world where deep sea mining is allowed. As trustees of the ocean, the common heritage of humankind, our Pacific governments must stand firm against corporate interests that are pushing to move ahead with deep-sea mining outside the ISA framework. If deep sea mining goes ahead, Pacific communities will suffer the economic, cultural and social consequences. We continue to call on all States to support a moratorium as the principled and responsible pathway to protect the ocean.”
Currently, 45 countries, including seven Pacific nations, support a moratorium or precautionary pause on deep sea mining. Last week, Australia’s Labor National Conference committed to supporting a moratorium, but the government has yet to make an official comment.
More of Germany’s electricity came from wind and solar power than fossil fuels for the first time ever in 2025.
Together, wind and solar power generated 225 terawatt hours (TWh) of electricity – accounting for 44% of the total in 2025 – with just 217TWh (43%) coming from fossil fuels.
Solar and onshore wind have grown rapidly under Germany’s “Energiewende” strategy over the past two decades, as the nation transitions away from both coal and nuclear power.
Renewables have recently faced mounting opposition from the far-right Alternative for Germany (AfD) party and the current coalition government has been trying to develop new gas-power plants.
Nevertheless, Carbon Brief analysis of Energy Institute data – shown in the chart below – illustrates how wind and solar have continued growing, emerging as the nation’s largest power source.
The success of renewables in Germany mirrors the EU as a whole, which also saw wind and solar overtake fossil-fuel power generation in 2025 for the first time.

Germany has various targets in place that require a rapid expansion of wind and solar power, including cutting economy-wide emissions to net-zero by 2045.
The nation is also aiming to increase renewables’ share of electricity consumption to 80% by 2030 to achieve a “largely climate neutral” power system by 2035. It aims to decarbonise its electricity entirely once coal power has been phased out, which has a deadline of “no later than” 2038.
(The renewables targets also include electricity generated from hydropower and bioenergy. The latter produces a relatively large share of Germany’s power – roughly a tenth in 2025.)
Germany has to rely on renewables more than neighbours, such as France and the UK, to achieve its climate goals. This is due to its phaseout of nuclear power, which is a key part of the “Energiewende” strategy.
Nuclear power has long faced widespread public opposition in Germany. This year, the centre-right chancellor Friedrich Merz described the nuclear phaseout as a “strategic mistake”, but the government has ruled out a return to conventional nuclear power.
The country has an official coal phaseout date of 2038, but experts say the country is on track to eliminate coal from its power supply years earlier. This is despite some pressure to temporarily slow the transition away from coal during the recent energy crisis.
(Very few outside the AfD are calling to scrap the coal phaseout altogether, but the government will publish a review of the timelines in August.)
While coal generation has fallen quickly, even as nuclear was being phased out, some argue that coal could have been cut more quickly if nuclear had remained.
Gas-power expansion has also been framed by the government in recent years as an essential component of Germany’s transition away from coal and nuclear power, to support a renewables-heavy grid.
The current government under Merz has tried to boost gas and recently adopted a law to provide state support for new gas-fired power plants. The plan is for these plants to be converted to run on “green hydrogen” by 2045, in order to meet the climate-neutrality goal.
Germany aims to install 115 gigawatts (GW) of onshore wind by 2030 and approved a record 20.8GW of new capacity in 2025.
Meanwhile, solar generation has reached unprecedented levels during the hot summer of 2026.
However, the government’s planned grid reforms have been criticised by the renewables industry for risking slowing down the energy transition. Under the proposals, renewables developers would only be granted automatic grid connections in areas with limited grid capacity if they waive compensation for future curtailed generation.
