NEW ANALYSIS: UK emissions fell 2.4% in 2025 as coal fell to a 400-year low. Incredibly, we used less coal last year than than in 1600, when Queen Elizabeth I was on the throne and Shakespeare was writing Hamlet.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.
Which just makes me want to share it again: www.nature.com/articles/d41...
Bar chart showing electric truck sales "skyrocketing" in china in 2025.
I follow this stuff closely. I wrote about it a few months ago. I'm shocked how fast this is happening for big trucks.
"China’s rapid adoption of electric trucks — which overtook gas-powered vehicle sales for the first time last yea"

Wow, that's pretty shocking! I just started reading "After the Spike: Population, Progress, and the Case for People" by Dean Spears and Michael Geruso, and it gives you a lot of food for thought on this topic.
Tremendous view of Zurich!

The threat to German auto producers isn't from Chinese cars flooding Germany. It's from Chinese cars flooding to emerging markets (red), where they're killing the market for German cars. That's not something EU tariffs on China are going to be able to fix...

Closing out my year with a journal editor shocker 🧵
Checking new manuscripts today I reviewed a paper attributing 2 papers to me I did not write. A daft thing for an author to do of course. But intrigued I web searched up one of the titles and that's when it got real weird...
@science.org chooses "The Rise of Renewables" as 2025's breakthrough
"Renewable energy, most of it from sunlight itself or from wind, ultimately driven by the Sun, overtook conventional energy on multiple fronts."
Amazing photos of the rise of the green giant!

China, the world’s biggest emitter, "is reducing its dependence on fossil fuels. Between 2015-2023, China’s consumption-based emissions rose 24%, less than half the growth of its economy (over 50%). For the past 18 months, its emissions have plateaued and many analysts believe they may have peaked."
GDP growth is decoupling from emissions, claims new report
"Countries [adding to 46% of global GDP] expanded their economies while cutting emissions, incl. Brazil, Colombia and Egypt. The most pronounced decouplings occurred in the UK, Norway and Switzerland." www.theguardian.com/environment/...
The European Union has triggered Article 122 to indefinitely immobilise the assets of the Russian Central Bank, worth a whopping €210 billion.
I explain what just happened and why this is such a big deal for Europeans.
🧵 Long thread.
Cool paper, thanks for sharing it!
Our new study an EU #fossil #phase-out is out in @natcomms.nature.com.
www.nature.com/articles/s41...
Afaik, this is the first #IAM study investigating a complete fossil phase-out. How much do we need to reduce fossils for the EU 2050 goal? And would even a full fossil phase-out be possible?
I agree. How "visible" these trends are in terms of easily accessible data may play a role. I imagine that new car registrations are easier to find as data and compare across countries than, say, sales of bikes and electric bikes.
The article in The Conversation is fascinating, thanks for sharing it :)
Totally agree, I just don't have the data at hand to say much about how modality changes may be affecting the oil demand for transport in China. Based on the report, it does not sound like they're having the most important factor, but that doesn't mean they are necessarily unimportant.
Based on the report, passenger cars seem the major driver.
"Railway passenger reached a record high of 3.5 billion in Q1-Q3 of 2025, a 6% year-on-year increase. Air travel passengers grew slightly slower, by 5.2% compared to 2024, to 581 million passengers."
But probably many factors are involved!
New energy vehicles' share of sales and vehicles on the road in China by category is going up.
The driver of lower oil demand for transport seems clear.
One in ten buses and passenger cars rolling on the streets in China in 2025 were new energy vehicles (BEV, PHEV, FCEV).
Average sales of new passenger cars for the past 12 months are now over 50% new energy vehicles.
"[Oil] demand in the transport sector has likely peaked in 2023, implying that China’s total oil demand may be approaching a peak, unless offset by the consumption growth in other sectors such as chemicals production."
Source: energyandcleanair.org/publication/...
Annual change in China’s oil consumption in transport compared to energy transition pathways. Oil consumption has fallen in 2025 nearly as much as in 2020.
China's oil consumption for transport may fall in 2025 almost as much as it did in 2020, during the pandemic.
"China’s oil consumption [for transport] is projected to fall for the 2nd consecutive year in 2025, declining by 4.6% year-on-year and by 7.2% compared to 2023."
Screenshot, job description: The “Ethical Technology Transitions to Mitigate Climate Change” program seeks one PhD student to be advised by Dr. Emily Grubert either in Notre Dame’s Civil and Environmental Engineering and Earth Sciences (CEEES) program (School of Engineering) or the Sustainable Development (SD) program (Keough School of Global Affairs). This position is fully funded for four years (anticipated stipend: $36,000/year) and will be supported by the resources associated with the Ethics and the Common Good program chair for three years, with remaining funding to come from other sources that might carry additional deliverable requirements (e.g., a secondary project) that will be clearly communicated to the candidate. The primary research area for this position will focus on ethical considerations related to technology deployment for reducing and removing greenhouse gas emissions from the atmosphere, with a particular focus either on modeling distributional effects of particular deployment patterns associated with net-zero greenhouse gas emissions pathways (CEEES PhD) or on designing governance systems for emerging technology systems, including Carbon Dioxide Removal (CDR); hydrogen; renewable electricity; or end use electrification technologies (SD PhD). Teaching requirements are aligned with the requirements of the specific degree program. Funding is available for conference attendance, and students will have the opportunity to work with and/or mentor undergraduate research assistants.
🚨job alert🚨
I'm looking to hire at least one PhD student for next year, looking at decarbonization-oriented technology deployment within an ethical frame of resource allocation and justice outcomes.
Full ad attached! Pref for CEEES admissions; deadline is 1 January.
Propose a session track or special session for #IST26 in Zürich (31 Aug–2 Sep 2026)!
Help us create an engaging, inclusive, and meaningful programme around the theme “Hope – in challenging times and sustainability transitions.”

Very interesting, thanks for sharing it!
Excited to share a new paper I got to help out with!
How much emissions do EVs cause through the electricity they consume? How do we know?
Our paper shows that frequently used metrics *over*-estimate EV emissions.

Yes, my favourite energy transition stat: Chinese sales of oil-powered cars peaked in **2017**🤯
