Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
EU sets 2040 goal
CUT CRUNCHED: The EU agreed on a legally binding target to reduce greenhouse gas emissions by 90% from 1990 levels by 2040, reported the EU Observer. The publication said that this agreement is “weaker” than the European Commission’s original proposal as it allows for up to five percentage points of a country’s cuts to be achieved by the use of foreign carbon credits. Even in its weakened form, the goal is “more ambitious than most other major economies’ pledges”, according to Reuters.
PETROL CAR U-TURN: Commission president Ursula von der Leyen has agreed to “roll back an imminent ban on the sale of new internal combustion-engined cars and vans after late-night negotiations with the leader of the conservative European People’s Party,” reported Euractiv. Car makers will be able to continue selling models with internal combustion engines as long as they reduce emissions on average by 90% by 2035, down from a previously mandated 100% cut. Bloomberg reported that the EU is “weighing a five-year reprieve” to “allow an extension of the use of the combustion engine until 2040 in plug-in hybrids and electric vehicles that include a fuel-powered range extender”.
CORPORATE PRESSURE: Reuters reported that EU countries and the European parliament struck a deal to “cut corporate sustainability laws, after months of pressure from companies and governments”. It noted that the changes exempt businesses with fewer than 1,000 employees from reporting their environmental and social impact under the corporate sustainability reporting directive. The Guardian wrote that the commission is also considering a rollback of environment rules that could see datacentres, artificial intelligence (AI) gigafactories and affordable housing become exempt from mandatory environmental impact assessments.
Around the world
- EXXON BACKPEDALS: The Financial Times reported on ExxonMobil’s plans to “slash low-carbon spending by a third”, amounting to a reduction of $10bn over the next 5 years.
- VERY HOT: 2025 is “virtually certain” to be the second or third-hottest year on record, according to data from the EU’s Copernicus Climate Change Service, covered by the Guardian. It reported that global temperatures from January-November were, on average, 1.48C hotter than preindustrial levels.
- WEBSITE WIPE: Grist reported that the US Environmental Protection Agency has erased references to the human causes of climate change from its website, focusing instead on “natural processes”, such as variations in the Earth’s orbit. On BlueSky, Carbon Brief contributing editor Dr Zack Labe described the removal as “absolutely awful”.
- UN REPORT: The latest global environment outlook, a largest-of-its-kind UN environment report, “calls for a new approach to jointly tackle the most pressing environmental issues including climate change and biodiversity loss”, according to the Associated Press. However, report co-chair Sir Robert Watson told BBC News that a “small number of countries…hijacked the process”, diluting its potential impact.
$80bn
The amount that Chinese firms have committed to clean technology investments overseas in the past year, according to Reuters.

Captured
The years 2023 and 2024 were the warmest on record – and 2025 looks set to join them in the top three. The causes of this apparent acceleration in global warming have been subject to a lot of attention in both the media and the scientific community. The charts above, drawn from a new Carbon Brief analysis, show how the natural weather phenomenon El Niño, sulphur dioxide (SO2) emissions from shipping, Chinese SO2, an eruption from the Hunga Tonga-Hunga Ha’apai volcano and solar cycle changes account for most of the “unusual warmth” of recent years. Dark blue bars represent the contribution of individual factors and their uncertainties (hatched areas), the light blue bar shows the combined effects and combination of uncertainties and the red bar shows the actual warming, compared with expectations.
Spotlight
Climate change boardgames
This week, Carbon Brief reports on the rise of climate boardgames.
Boardgames have always made political arguments. Perhaps the most notorious example is the Landlord’s Game published by US game designer and writer Lizzie Magie in 1906, which was designed to persuade people of the need for a land tax.
This game was later “adapted” by US salesman Charles Darrow into the game Monopoly, which articulates a very different set of values.
In this century, game designers have turned to the challenge of climate change.
Best-selling boardgame franchise Catan has spawned a New Energies edition, where players may choose to “invest in clean energy resources or opt for cheaper fossil fuels, potentially causing disastrous effects for the island”.
But perhaps the most notable recent release is 2024’s Daybreak, which won the prestigious Kennerspiel des Jahre award (the boardgaming world’s equivalent of the Oscars).
Rolling the dice
Designed by gamemakers Matteo Menapace and Matt Leacock, Daybreak sees four players take on the role of global powers: China, the US, Europe and “the majority world”, each with their own strengths and weaknesses.
Through playing cards representing policy decisions and technologies, players attempt to reach “drawdown”, a state where they are collectively producing less CO2 than they are removing from the atmosphere.
“Games are good at modelling systems and the climate crisis is a systemic crisis,” Daybreak co-designer Menapace told Carbon Brief.
In his view, boardgames can be a powerful tool for getting people to think about climate change. He said:
“In a video game, the rules are often hidden or opaque and strictly enforced by the machine’s code. In contrast, a boardgame requires players to collectively learn, understand and constantly negotiate the rules. The players are the ‘game engine’. While videogames tend to operate on a subconscious level through immersion, boardgames maintain a conscious distance between players and the material objects they manipulate.
“Whereas videogames often involve atomised or heavily mediated social interactions, boardgames are inherently social experiences. This suggests that playing boardgames may be more conducive to the exploration of conscious, collective, systemic action in response to the climate crisis.”
Daybreak to Dawn
Menapace added that he is currently developing “Dawn”, a successor to Daybreak, building on lessons he learned from developing the first game, telling Carbon Brief:
“I want the next game to be more accessible, especially for schools. We learned that there’s a lot of interest in using Daybreak in an educational context, but it’s often difficult to bring it to a classroom because it takes quite some time to set up and to learn and to play.
“Something that can be set up quickly and that can be played in half the time, 30 to 45 minutes rather than an hour [to] an hour and a half, is what I’m currently aiming for.”
Dawn might also introduce a new twist that explores whether countries are truly willing to cooperate on solving climate change – and whether “rogue” actors are capable of derailing progress, he continued:
“Daybreak makes this big assumption that the world powers are cooperating, or at least they’re not competing, when it comes to climate action. [And] that there are no other forces that get in the way. So, with Dawn, I’m trying to explore that a bit more.
“Once the core game is working, I’d like to build on top of that some tensions, maybe not perfect cooperation, [with] some rogue players.”

DeBriefed 12 December: EU under ‘pressure’; ‘Unusual warmth’ explained; Rise of climate boardgames
In recent years, the monsoon season in Pakistan has taken a new and dangerous turn.
July and August typically bring high levels of rainfall across the country, and while flooding isn’t uncommon, the extent and severity could be readily predicted.
These patterns have now changed. In 2022, extreme rainfall swept Pakistan and huge swathes of the country were under water. Sindh province experienced levels of rain 508% above average for the time of year.
Extreme weather in Pakistan is becoming the norm. The past 15 years have brought widespread flooding, loss of life and billions in financial costs. A post-disaster report, produced by the Pakistan Government, stated that the 2022 floods were “a wake-up call for systemic changes to address the underlying vulnerabilities to natural hazards”, citing the country’s lack of climate-resilient infrastructure.
But heavy rainfall is only one of the water-related issues that Pakistan faces. In a country with huge geographical diversity, from sweltering deserts to freezing mountain tops, the water stresses are equally as varied. In many regions the key concern is a lack of reliable, clean water that can be used to grow crops and feed families.
We must invest in early warning systems to tackle crises like Kenya’s drought
The risks of the Indus
The Indus River plays a critical role in Pakistan. This major artery travels almost the entire length of the country, an estimated 2,000 km, from the Himalayas to the Arabian Sea. It is a crucial economic lever, supporting nearly 90% of Pakistan’s food production and 25% of its overall GDP. What happens to this river – both human and natural impacts – has huge consequences for the rest of the country.
The government and civil society agree that urgent action is required to protect Pakistan’s fragile water resources. A new adaptation project – SAFER Pakistan – is seeking to address these concerns with solutions that can be used to solve similar climate-related issues elsewhere.
The US$ 10 million project is led by ICIMOD, an intergovernmental research centre, alongside UNICEF, and financed by the Adaptation Fund. The intention is to tackle six key issues that people face in the Indus Basin: cryosphere risks, drying springs, groundwater, pollution, unsustainable water use, and community resilience.
In practice this means exploring different solutions that put communities in control of their own adaptive capacity. One solution under development is the use of community early warning systems.
Pakistan’s ‘monster disaster’ brings climate compensation into focus
A warning sign
According to researchers, early warning systems “aim to empower affected communities against hazards and help them to sufficiently prepare before disasters strike.”
The northern provinces of Pakistan – Gilgit-Baltistan and Khyber Pakhtunkhwa – are the main focus for testing these systems. In this mountainous region the Indus is fed by thousands of glaciers which sustain water flow during the dry season. At the same time, increased temperatures and unpredictable weather patterns are changing how these glaciers behave, leading to avalanches, increased snowmelt, and landslides.
As glaciers start to melt due to climate change, they can form large lakes high up on the mountain that can pose a serious threat to the communities living below. When these natural dams fail, huge quantities of water come careening down the mountain, a phenomenon called glacial lake outburst flood.
The SAFER project is exploring how to use local knowledge and observations of the mountain to ensure people know how and when to evacuate when these outbursts occur. This human intelligence will be combined with data from remote sensors to save lives and livelihoods. In total, over 435,000 people will be impacted by the project.
“Early warning systems often serve as the backbone of a multi-faceted response to reduce climate disaster risk,” commented Mikko Ollikainen, head of the Adaptation Fund. “But local information is often just as valuable as the real-time data you receive from sensors or satellites,” he added.
Climate disasters challenge right to safe and adequate housing
Shaping an effective response
Community early warning systems – together with other preventive adaptation measures – are proving a popular solution to extreme weather events.
A separate adaptation project in the mountains of Central Asia is grappling with the same problem of glacial flooding. In this case, with US$6.5 million in funding from the Adaptation Fund, UNESCO has been implementing early warning systems across Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan for the past five years, with considerable success.
Diana Aripkhanova, a project officer at UNESCO, and based in Kazakhstan, told Climate Home that glacier lake outburst floods “represent an increasing climate-related hazard across the high mountain regions of Central Asia”.
“These events can trigger destructive floods and debris flows that affect downstream communities, infrastructure, and livelihoods,” she added.
The project utilises real-time data drawn from weather monitoring stations with community preparedness to shape a fast and effective response to life-threatening flooding. This includes training people on evacuation routes, safe locations and simulation drills. In addition, the project has tried preventative measures such as planting hundreds of trees in valleys prone to landslides to provide greater stabilisation.
In total, four early warning systems have been installed across the four countries involved in the project covering seven high-risk areas. As a result, UNESCO estimates these systems are protecting over 100,000 people.
“Early warning systems are a key risk reduction measure, allowing communities to evacuate in time and reduce potential loss of life and damage to assets,” added Aripkhanova.
Community participation
The active role of each community is built into these interventions. Ensuring local people are core contributors is seen as crucial to building long-term climate resilience.
These communities are witnessing the threats from climate change materialise on a yearly basis, and researchers are now tapping into that understanding when implementing adaptation projects.
After the 2022 floods, Pakistan’s development minister, Ahsan Iqbal, wrote that “there is an opportunity to do things differently” and that “enhancing Pakistan’s resilience to shocks and stresses amidst climate change, especially for the poorest…is essential for the country’s future.”
The climate shocks remain as strong as ever, but using the right tools and simple solutions can soften the blow when they occur.

From the Amazon to the Mekong, migratory freshwater fish underpin food security for millions, but over 300 species need urgent conservation intervention, warns a new UN report.
Beneath the surface of the planet’s rivers and lakes, the historically heaving migrations of freshwater fish are thinning out. The blubbery-lipped Siamese giant carp of Asia’s Mekong River, the mottled brown goonch of India’s Ganges and the ancient-in-appearance beluga sturgeon of Europe’s Danube River are declining.
