In the Scottish city of Aberdeen, a debate over the region’s energy transition away from fossil fuels is playing out over roughly one square mile of green space.
In question is a proposed development called the Energy Transition Zone (ETZ), which is intended to bring in more renewable energy investments as the city tries to cut its dependence on the oil and gas industry that has defined it for half a century.
As the UK’s new Labour government promises not to issue any more oil and gas licenses, the future of the sector is in doubt and the company behind the ETZ says it wants to “protect and create as many jobs as possible” in the region through investing in clean energy.
But the ETZ has received significant pushback from community groups in the part of Aberdeen it is destined for. That’s because the proposed development, as currently designed, would pave over about a third of St. Fittick’s Park in Torry, the only public green space in one of Scotland’s most neglected urban areas.
The battle over St Fittick’s Park illustrates the friction that is emerging more frequently around the world as the ramp-up of clean energy infrastructure changes communities. Climate Home has reported on these tensions provoked by Mexico’s wind farms, Namibia’s desert hydrogen zone, Indonesia’s nickel mines and Germany’s Tesla gigafactory.
Just transition?
The ETZ is backed by BP, Shell and local billionaire Ian Wood, whose Wood Group made its money providing engineering and consulting services to the oil and gas industry.
The plan is to create campuses focused on hydrogen, carbon capture and storage, offshore wind, and skills development in an area initially the size of 50 football pitches, but expanding as private investment grows.
To this end, ETZ Ltd – the company set up to build and run the zone – will receive up to £80m ($103m) from the UK and Scottish governments. Announcing some of that funding in 2021, the Scottish government’s then net zero, energy and transport secretary Michael Matheson said “urgent, collective action is required in order to ensure a just transition to a net-zero economy”, adding “Scotland can show the rest of the world how it’s done”.
But many Scottish climate campaigners don’t see this as a just transition. About 100 of them travelled to St. Fittick’s Park last week to hold a five-day “Climate Camp” in a clearing that would become part of the ETZ.
One camper, who did not want to give her name, told Climate Home that the energy transition should not “exacerbate existing inequalities, but try to redress existing inequalities”. A just transition, she said, must protect both workers in the fossil fuel industry and community green spaces.
Another protestor who did not want to giver her full name is Torry resident Chris. She said “the consultation process was flawed”. Not many people participated to start with, and some stopped going to meetings because “they were disillusioned with the way that good ideas were co-opted and then used to justify the expansion of the industrial area into the park”, she added.

Local Member of the Scottish Parliament (MSP) Maggie Chapman, from the Scottish Green Party, agreed, adding “the best transition zone plan in the world will fail” if it is done to a community rather than with meaningful input from them.
Another protesting resident, David Parks, said wealthier parts of the city would not have been disregarded in the same way. “You wouldn’t see this in Old Aberdeen and Rosemount,” he said. “[Torry] is just kind of the dumping ground for all these projects that you wouldn’t get off with anywhere else.”
Industrial developments have encroached on the old fishing town of Torry for decades. Today, residents are hemmed in by an industrial harbour, roads and a railway and live alongside a waste-to-energy incinerator, a sewage plant, and a covered landfill.

Some of the activists also take issue with the emphasis the ETZ places on hydrogen and carbon capture and storage, which they see as “greenwashing”.
Hydrogen is a fuel that can be made without producing greenhouse gas emissions, and used to decarbonise industries like steel-making which are difficult to clean up.
But a Climate Camp spokesperson told Climate Home that, “given the industry’s tendencies” and the fact that 99% of hydrogen is currently made using fossil fuels, they assume it will be produced in a polluting way at the ETZ.
Backers respond
ETZ Ltd told Climate Home in a statement that the project is committed to collaborating with the local community, particularly on efforts to refurbish what would be the remainder of the park.
While the ETZ’s opponents argue there are existing industrial brownfield sites in the area that could be used instead of the park, the company said the area in St. Fittick’s Park next to the port is essential for the development to draw in substantial investment for renewables and for Aberdeen to compete in a new energy market.
Many brownfield sites are already planned for use by the ETZ, and would not provide the kind of logistical access needed for the planned projects, they added.

“Almost all other ports in Scotland are making similar investments, and we simply don’t want Aberdeen to miss out on the opportunity to position itself as a globally recognised hub for offshore renewables and the significant job benefits this will bring,” said the statement.
The company added that the original plans for use of the park had been considerably reduced and the new master plan includes several measures to revitalise parts of the park and boost public access. It includes several parklets, a boardwalk, enhanced wetlands and a skate and BMX bike park.
While the oil industry’s backing has raised campaigners’ eyebrows, ETZ Ltd said the industry’s involvement is key to ensuring the development of skills and jobs central to the ETZ’s goals.
The section of St. Fittick’s Park up for development was rezoned in 2022 by the Aberdeen City council in order to allow industrial use of the land. Campaigners have challenged that decision and Scotland’s highest civil court will issue a judicial review later this month.
“You can’t just switch it off”
The ETZ dispute is just one example of efforts across Scotland to navigate the planned shift away from fossil fuels to renewable energy.
Tools to support a transitioning workforce have stalled. An offshore skills passport is meant to streamline and unify the certification process for both the fossil fuel and renewable offshore industries, to enable workers to go more easily from one sector to the other. But it was delayed for years before a “roadmap to a prototype” was released in May this year.
“The people can see a future, but it’s not happening – and they can see the current reality, which is [fossil fuels] declining, and that makes it very challenging,” said Paul de Leeuw, director of the Energy Transition Institute at Robert Gordon University.
He said the focus needs to be on manufacturing and the supply chain, as that supports about 90% of employment in renewables such as solar and wind power. “If you don’t get investment, you don’t get activity, you don’t get the jobs,” he added.
That’s the key concern for Alec Wiseman, who spoke to Climate Home while walking his dog in St. Fittick’s Park on Saturday. He seemed mostly unbothered by the climate camp, but complained it meant he couldn’t let his dog off leash.

A Torry resident, Wiseman worked offshore for 25 years. He said he wants the ETZ to leave the park alone – and he also wants the overall energy transition to slow down until there is a clear plan.
“The government needs to sit down with the oil companies and figure out something proper” for both the transition and the ETZ, he said, expressing scepticism about employment in wind energy. Overall, operating wind farms, once they’re up and running, does not require as many skilled workers as operating an oil and gas field. “You can’t just switch it off [the oil and gas],” he said.
Lack of planning is what worries Jake Molloy, the recently-retired regional head of the Rail Maritime and Transport workers (RMT) union. Before leading the union, Molloy spent 17 years working offshore, and now sits on Scotland’s Just Transition Commission. He has spent years advocating for a fair deal on behalf of workers and local communities.
“We need to do that value-sharing piece, that community-sharing piece, which was lost with oil and gas,” he said, referencing the privatisation of the industry in the 1980s. Right now, he says, communities that bear the brunt of the impact of oil and gas production don’t see the majority of the benefits – those flow to corporations. “If we allow that to happen again, we’re a million miles away from a just transition,” he warned.
UK court ruling provides ammo for anti-fossil fuel lawyers worldwide
Molloy also thinks the investment and jobs promised by the ETZ are not realistic, because previous changes to government policies caused too much whiplash, making investors shaky. However, he is curious about what will come from Labour’s announcement of Great British Energy, described as a “publicly-owned clean energy company” headquartered in Scotland. He also hopes to see climate change addressed on a crisis footing, similar to the approach to the COVID pandemic.
There are indications of renewed momentum on renewable energy in the UK. The Labour government has already lifted an effective ban on onshore wind in England and brought together a net-zero task force led by the former head of the UK’s Climate Change Committee, Chris Stark.
“In the context of an unprecedented climate emergency,” the ETZ said in a statement, “there are widespread calls from government and industry for energy transition activities to be accelerated.”
But, for many, it is still too soon to know whether that shift will materialise, and be implemented in a just way.
“The opportunities are there,” said MSP Chapman. But, she added, “it requires political and social will to make it happen and that’s the big challenge.”

Scottish oil-town plan for green jobs sparks climate campers’ anger over local park
Human-caused greenhouse gas (GHG) emissions in 2024 continued to drive global warming to record levels.
This is the stark picture that emerges in the third edition of the “Indicators of Global Climate Change” (IGCC) report, published in Earth System Science Data.
IGCC tracks changes in the climate system between Intergovernmental Panel on Climate Change (IPCC) science reports.
In doing so, the IGCC fills the gap between the IPCC’s sixth assessment (AR6) in 2021 and the seventh assessment, expected in 2028.
Following IPCC methods, this year’s assessment brings together a team of over 60 international scientists, including former IPCC authors and curators of vital global datasets.
As in previous years, it is accompanied by a user-friendly data dashboard focusing on the main policy-relevant climate indicators, including GHG emissions, human-caused warming, the rate of temperature change and the remaining global carbon budget.
Below, we explain this year’s findings, highlighting the role that humans are playing in some of the fundamental changes the global climate has seen in recent years.
(For previous IGCC reports, see Carbon Brief’s detailed coverage in 2023 and 2024.)
An ‘unexceptional’ record high
Last year likely saw global average surface temperatures hit at least 1.5C above pre-industrial levels. This aligns with other major assessments of the Earth’s climate.
Our best estimate is a rise of 1.52C (with a range of 1.39-1.65C), of which human activity contributed around 1.36C. The rest is the result of natural variability in the climate system, which also plays a role in shaping global temperatures from one year to the next.
Our estimate of 1.52C differs slightly from the 1.55C given by the World Meteorological Organisation (WMO) state of the global climate 2024 report, published earlier this year. This is because they make slightly different selections on which of the available global land and ocean temperature datasets to include. (The warming estimate has varied by similar amounts in past years and future work will aim to harmonise the approaches.)
The height of 2024’s temperatures, while unprecedented in at least the last 2,000 years, is not surprising. Given the high level of human-induced warming, we might currently expect to see annual temperatures above 1.5C on average one year in six.
However, with 2024 following an El Niño year, waters in the North Atlantic were warmer than average. These conditions raise this likelihood to an expectation that 1.5C is surpassed every other year.
From now on, we should regard 2024’s observed temperatures as unexceptional. Temperature records will continue to be broken as human-caused temperature rise also increases.
Longer-term temperature change
Despite observed global temperatures likely rising by more than 1.5C in 2024, this does not equate to a breach of the Paris Agreement’s temperature goal, which refers to long-term temperature change caused by human activity.
IGCC also looks at how temperatures are changing over the most recent decade, in line with IPCC assessments.
Over 2015-24, global average temperatures were 1.24C higher than pre-industrial levels. Of this, 1.22C was caused by human activity. So, essentially, all the global warming seen over the past decade was caused by humans.
Observed global average temperatures over 2015-24 were also 0.31C warmer than the previous decade (2005-14). This is unsurprising given the high rates of human-caused warming over the same period, reaching a best estimate of 0.27C per decade.
This rate of warming is large and unprecedented. Over land, where people live, temperatures are rising even faster than the global average, leading to record extreme temperatures.
But every fraction of a degree matters, increasing climate impacts and loss and damage that is already affecting billions of people.
Driven by emissions
Undoubtedly, these changes are being caused by GHG emissions remaining at an all-time high.
Over the last decade, human activities have released, on average, the equivalent of around 53bn tonnes of CO2 into the atmosphere each year. (The figure of 53bn tonnes expresses the total warming effect of CO2 and other greenhouse gases, such as methane and nitrous oxide, using CO2 as a reference point.)
Emissions have shown no sign of the peak by 2025 and rapid decline to net-zero required to limit global warming to 1.5C with no or limited “overshoot”.
Most of these emissions were from fossil fuels and industry. There are signs that energy use and emissions are rising due to air conditioning use during summer heatwaves. Last year also saw high levels of emissions from tropical deforestation due to forest fires, partly related to dry conditions caused by El Niño.
Notably, emissions from international aviation – the sector with the steepest drop in emissions during the Covid-19 pandemic – returned to pre-pandemic levels.
The amount of CO2 in the atmosphere, alongside the other major GHGs of methane (CH4) and nitrous oxide (N2O), is continuing to build up to record levels. Their concentrations have increased by 3.1, 3.4 and 1.7%, respectively, since the 2019 values reported in the last IPCC assessment.
At the same time, aerosol emissions, which have a cooling effect, are continuing to fall as a result of important efforts to tackle air pollution. This is currently adding to the rate of GHG warming.
Notably, cutting CH4 emissions, which are also short-lived in the atmosphere, could offset this rise. But, again, there is no real sign of a fall – despite major initiatives such as the Global Methane Pledge.
The effect of all human drivers of climate change on the Earth’s energy balance is measured as “radiative forcing”. Our estimate of this radiative forcing in 2024 is 2.97 Watts per square metre (W/m2), 9% above the value recorded in 2019 that was quoted in the last IPCC assessment.
This is shown in the figure below, which illustrates the percentage change in an array of climate indicators since the data update given in the last IPCC climate science report.
Continued emissions and rising temperatures are meanwhile rapidly eating into the remaining carbon budget, the total amount of CO2 that can be emitted if global warming is to be kept below 1.5C.
Our central estimate of the remaining carbon budget from the start of 2025 is 130bn tonnes of CO2.
This has fallen by almost three-quarters since the start of 2020. It would be exhausted in a little more than three years of global emissions, at current levels.
However, given the uncertainties involved in calculating the remaining carbon budget, the actual value could lie between 30 and 320bn tonnes, meaning that it could also be exhausted sooner – or later than expected.
Beyond global temperatures
Our assessment also shows how surplus heat is accumulating in the Earth’s system at an accelerating rate, becoming increasingly out of balance and driving changes around the world.
The data and their changes are displayed on a dedicated Climate Change Tracker platform, shown below.
The radiative forcing of 2.97 W/m2 adds heat to the climate system. As the world warms in response, much of this excess heat radiates to space, until a new balance is restored. The residual level of heating is termed the Earth’s “energy imbalance” and is an indication of how far out of balance the climate system is and the warming still to come.
This residual rate of heat entering the Earth system has now approximately doubled from levels seen in the 1970s and 1980s, to around 1W/m2 on average during the period 2012-24.
Although the ocean is storing an estimated 91% of this excess heat, mitigating some of the warming we would otherwise see at the Earth’s surface, it brings other impacts, including sea level rise and marine heatwaves.
Global average sea level rise, from both the melting of ice sheets and thermal expansion due to deep ocean warming, is included in the IGCC assessment for the first time.
We find that it has increased by around 26mm over the last six years (2019-24), more than double the long-term rate. This is the indicator that shows the clearest evidence of an acceleration.
Sea level rise is making storm surges more damaging and causing more coastal erosion, having the greatest impact on low-lying coastal areas. The 2019 IPCC special report on the oceans and cryosphere estimated that more than one billion people would be living in such low-lying coastal zones by 2050.
Multiple indicators
Overall, our indicators provide multiple lines of evidence all pointing in the same direction to provide a clear and consistent – but unsurprising and worsening – picture of the climate system.
It is also now inevitable that global temperatures will reach 1.5C of long-term warming in the next few years unless society takes drastic, transformative action – both in cutting GHG emissions and stopping deforestation.
Every year of delay brings reaching 1.5C – or even higher temperatures – closer.
This year, countries are unveiling new “nationally determined contributions” (NDCs), the national climate commitments aimed at collectively reducing GHG emissions and tackling climate change in line with the Paris Agreement.
While the plans put forward so far represent a step in the right direction, they still fall far short of what is needed to significantly reduce, let alone stop, the rate of warming.
At the same time, evidence-based decision-making relies on international expertise, collaboration and global datasets.
Our annual update relies on data from NASA and the National Oceanic and Atmospheric Administration (NOAA) and input from many of their highly respected scientists. It is this type of collaboration that allows scientists to generate well-calibrated global datasets that can be used to produce trusted data on changes in the Earth system.
It would not be possible to maintain the consistent long-term datasets employed in our study if their work is interrupted.
At a time when the planet is changing at the fastest rate since records began, we are at risk of failing to track key indicators – such as greenhouse gas concentrations or deep ocean temperatures – and losing core expertise that is vital for understanding the data.

Guest post: How the world’s rivers are releasing billions of tonnes of ‘ancient’ carbon
The perception of how the land surface releases carbon dioxide (CO2) typically conjures up images of large-scale deforestation or farmers churning up the soil.
However, there is an intriguing – and underappreciated – role played by the world’s rivers.
Right now, plants and soils absorb about one-third of the CO2 released by human activity, similar to how much the oceans take up.
Over thousands to millions of years, some of this land-fixed carbon can end up being buried in sediments, where it eventually forms rocks.
The waters that feed rivers flow through plants, soils and rocks in landscapes, picking up and releasing carbon as they go.
This process is generally considered to be a sideways “leakage” of the carbon that is being taken up by recent plant growth.
However, the age of this carbon – how long it resided in plants and soils before it made it into rivers and then to the atmosphere – has remained a mystery.
If the carbon being released by rivers is young, then it can be considered a component of relatively quick carbon cycling.
However, if the carbon is old, then it is coming from landscape carbon stores that we thought were stable – and, therefore, represents a way these old carbon stores can be destabilised.
In our new study, published in Nature, we show that almost 60% of the carbon being released to the atmosphere by rivers is from these older sources.
In total, this means the world’s rivers emit more than 7bn tonnes of CO2 to the atmosphere each year – more than the annual fossil-fuel emissions from North America.
This means that there is a significant leak of carbon from old stores that we thought were safely locked away.
Previous work has shown that local land-use change, such as deforestation and climate-driven permafrost thaw, will directly release old carbon into rivers. Whether this is happening at the global scale remains a significant unknown for now.
Who are you calling old?
How do you tell how old carbon is? We employ the same technique that is used to determine the age of an archaeological relic or to verify the age of a vintage wine – that is, radiocarbon dating.
Radiocarbon is the radioactive isotope of carbon, which decays at a known rate. This enables us to determine the age of carbon-based materials dating back to a maximum age of about 60,000 years old.
We know that some of the carbon that rivers release is very young, a product of recent CO2 uptake by plants.
We also know that rivers can receive carbon from much older sources, such as the decomposition of deep soils by microbes and soil organisms or the weathering and erosion of ancient carbon in rocks.
Soil decomposition can release carbon ranging from a few years to tens of thousands of years. An example of very old soil carbon release is from thawing permafrost.
Rock weathering and erosion releases carbon that is millions of years old. This is sometimes referred to as “radiocarbon-dead” because it is so old all the radiocarbon has decayed.
Rivers are emitting old carbon
In our new study, we compile new and existing radiocarbon dates of the CO2 emissions from around 700 stretches of river around the world.
We find that almost 60% of the carbon being released to the atmosphere by rivers is from older sources (hundreds to thousands of years old, or older), such as old soil and ancient rock carbon.
In the figure below, we suggest how different processes taking place within a landscape can release carbon of different ages into rivers, driving its direct emission to the atmosphere.
So, while rivers are leaking some modern carbon from plants and soils as part of the landscape processes that remove CO2 from the atmosphere, rivers are also leaking carbon from much older landscape carbon stores.
One major implication of this finding is that modern plants and soils are leaking less carbon back to the atmosphere than previously thought, making them more important for mitigating human-caused climate change.
We find that the proportion of old carbon contributing to river emissions varies across different ecosystems and the underlying geology of the landscapes they drain.
In the figure below, we show that landscapes underlain by sedimentary rocks, which are the most likely to contain substantial ancient (or “petrogenic”) carbon, also had the oldest river emissions. We also show that the type of ecosystem (biome) was also important, although the patterns were less clear.
What is obvious is that at least some old carbon was common across most of the rivers we observed, regardless of size and location.
We provide evidence that there is a geological control on river emissions. And the variability in the ecosystem also indicates important controlling factors, such as soil characteristics, vegetation type and climate – especially rainfall patterns and temperature which are known to impact the rate of carbon release from soils and rock weathering.
Are old carbon stores stable?
Long-term carbon storage in soils and rocks is an important process regulating global climate.
For example, the UK’s peatlands are important for regulating climate because they can store carbon for thousands of years. That is why restoring peatlands is such a great climate solution.
Rivers emit more than 7bn tonnes of CO2 to the atmosphere each year – that’s equivalent to about 10-20% of the global emissions from fossil fuel burning annually.
If 60% of river carbon emissions are coming from old carbon stores, then this constitutes a significant leak of carbon from old stores we thought were safely locked away.
Another major implication of our study is that these old carbon stores can be mobilised and routed directly to the atmosphere by rivers, which would exacerbate climate change if these stores are further destabilised.
As can be seen in the figure below, we found that river carbon emissions appeared to be getting older since measurements first began in the 1990s (lower F14Catm means older radiocarbon ages).
We found that river carbon emissions appeared to be getting older since measurements first began in the 1990s.
While there are several caveats to interpreting this trend, it is a warning sign that human activities, especially climate change, could intensify the release of carbon to the atmosphere via rivers.
Given the strong link between soil carbon and river emissions, if this trend is a sign of human activity disturbing the global carbon cycle, it is likely due to landscape disturbance mobilising soil carbon.
Using rivers to monitor global soil carbon storage
Rivers collect waters from across the landscapes they flow through and therefore provide a tool to track processes happening out of sight.
A drop of water landing in a landscape travels through soils and rock before reaching the river, and its chemistry, including its radiocarbon age, reflects the processes occurring within the landscape.
Monitoring the age of carbon in rivers can therefore tell you a lot about whether their landscapes are storing or releasing carbon.
This has been shown to help identify carbon loss in degraded tropical peatlands, thawing Arctic permafrost and due to deforestation.
River radiocarbon is sensitive to environmental change and could therefore be a powerful monitoring tool for detecting the onset of climate tipping points or the success of landscape restoration projects, for example.
While we present data spread out across the world, there are quite a few gaps for important regions, notably where glacier change is happening and others where droughts and flood frequencies are changing.
These include areas with low amounts of data in Greenland, the African continent, the Arctic and Boreal zones, the Middle East, eastern Europe, western Russia, Central Asia, Australasia and South America outside of the Amazon.
All these regions have the potential to store carbon in the long-term and we do not yet know if these carbon stores are stable or not under present and future climate change.
River radiocarbon offers a powerful method to keep tabs on the health of global ecosystems both now and into the future.
