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
Like so many people around the world, I am experiencing a sense of horror at the escalating violence in Iran and the Middle East. Greenpeace has called for all parties to immediately halt further military action, for international law to be fully upheld, and for a return to diplomacy to stop the suffering of civilians. The people of Iran, and all people, everywhere, have the inalienable right to live free of violence, fear and coercion. As humans we grieve for lives lost, and for all those who suffer.
But while countless people experience the consequences of this latest mass violence, some interests will no doubt attempt to benefit from the crisis. We can expect that fossil fuel corporations and lobbyists will cynically use the closure of the Strait of Hormuz-a major shipping route for oil and gas-to propagandise for increased fossil fuel production.
The practical reality is that a country as rich in renewable sources of energy as Australia should not be hostage to the global fossil fuel trade. The pursuit of fossil fuels–coal, oil and gas–have been the source of vast scale conflict, violence and geopolitical volatility for far too long. This will only accelerate as the climate crisis–itself driven primarily by fossil fuel extraction and burning–continues to put greater pressure on natural and social systems.
The truth is that the only absolute way to provide true energy security for the world is to phase out fossil fuels rapidly and deliberately, at emergency speed and scale, and to accelerate the shift to modern, renewable energy.
It’s in the strategic interest of all countries, including Australia, to unhook from volatile sources of energy. As long as our world runs on oil and gas, our peace, security and our pockets will always be at the mercy of geopolitics. As Professor Hussein Dia argued in The Conversation yesterday, this latest war in the Middle East shows why quitting oil is more important than ever.
These events are another jarring reminder that Australia doesn’t need more fossil fuel investment–we need less.
Locally controlled renewables are the best way to address the structural vulnerability at the heart of this recurring crisis. Ultimately, our freedom and security, prosperity and sustainability, are all best served by shifting from fossil fuels to renewable energy.
Dependence on fossil fuels makes all of us hostage to geopolitics and the whims of tyrants.

The Sierra Club and Southern Environmental Law Center are suing over state regulators’ approval of new gas turbines at Plant Bowen, citing concerns about worsening air quality.
Atlanta has spent decades battling smog and air pollution. Now, state regulators have cleared the way for a major natural gas expansion at Georgia Power’s Plant Bowen, a massive coal-fired power plant roughly 40 miles northwest of downtown that could add hundreds of tons of new air pollution each year to a region already struggling with unhealthy air.
Environmental Groups Challenge Air Permit for Natural Gas Expansion at Atlanta Plant
Oil prices jumped after the United States and Israel attacked Iran. Experts say the effects on oil and gas prices will depend on how long the war lasts and whether Iran damages energy infrastructure.
The U.S. and Israeli war against Iran is disrupting energy markets and driving oil and gas prices higher in the United States and globally. While those increases are modest so far, experts say the war has the potential to cause more severe and lasting impacts if Iran damages the region’s energy infrastructure or restricts shipping through the Strait of Hormuz.
