Paris-Berlin sleeper: low carbon, 2 years old, constantly full, but currently losing SNCF a few million EUR/yr Intl Jet fuel tax exemptions are 80 years old and cost the EU 22 million EUR/yr for the Paris-Berlin route alone. And you're cutting... the sleeper? www.theguardian.com/travel/2025/...

The potential for CO2 is prudently estimated at 0.7°C of warming. Meaning if we stay on the current trajectory of +2.7°C in 2100 (and not even net-zero by then), it will hardly be possible to reverse to +1.5°C.

🌳 🔥 🌎 Our new paper: The extreme fire-prone #weather underpinning some of the worst #wildfire episodes this century has become more than twice as likely due to #climate change—a trend now evident across much of the world's tropical and mid-latitude #forests. www.nature.com/articles/s41...

Influx of Chinese EVs along the lines of Japanese/Korean cars in the 80s: negligible overall GDP impact, acc to IMF calculations. Climate change, natural disaster scenario, until 2030: -4.7% of GDP in the euro area. Just to put that into perspective. www.ecb.europa.eu/press/blog/d...

Dans son rapport annuel, le Haut Conseil pour le climat regrette que le rythme de décarbonation ait "beaucoup ralenti" en France en 2024 et déplore les reculs environnementaux (ZFE, ZAN, etc). Ces retards "importants" sont "incompatibles" avec les objectifs 2030/2050 www.lemonde.fr/planete/arti...

Very warm congratulations to @linusmattauch.bsky.social! Very well deserved.

The energy transition continues to be the best beat. "India’s plan to expand one of the world’s largest coal power fleets in order to meet its growing energy needs is being undone by a shortage of companies able and willing to help build new plants." 🎁 link www.bloomberg.com/news/article...

Dans un nouveau working paper co-écrit avec @ondineberland.bsky.social, nous trouvons que les femmes ont une empreinte carbone 26% moins élevée que les hommes dans l’alimentation et les transports en 🇫🇷 Ce n’est pas seulement dû à des differences biologiques ou sur le marché du travail. Un🧵(1/11)

In this new paper joint with @ondineberland.bsky.social, featured in The Guardian, we show that : -women in France emit 26% less CO₂ than men from food & transpor - the gap isn’t just down to biology or labor market differences. Thread will follow, see full paper here: www.lse.ac.uk/granthaminst...

One of the many emergent issues with the phrase 'net zero' is that it became a proxy phrase for 'the politics of climate policies', and not 'stopping the heating of the atmosphere and oceans so that we don't fucking die' Imagine a debate about "will Labour stick with or abandon cancer prevention"

En France, la pollution aux particules fines augmente l'absentéisme des salariés, baisse leur productivité, affecte les consommateurs et nuit in fine aux entreprises. J'explique les résultats de notre étude menée avec Hélène Ollivier au micro de @vgarin.bsky.social pour RTL: shorturl.at/nbubg

There’s so much happening right now, I thought I’d put together a running thread on the dismantling of #climate and research and knowledge infrastructure in the United States 🧵

@carbonbrief.org has a solid piece summarising the current state of play on the cause of the blackout. Some nice quotes and covers many of the factors that have come up in the past few days. Of course, the main takeaway remains that we won't know for sure until the ongoing investigations are done.

In "Colluding Against Environmental Regulation," we study collusion among firms against imperfectly monitored environmental regulation, applied to a case study about automakers and diesel vehicle emissions. With Jorge Alé-Chilet, Cuicui Chen, and Mathias Reynaert. @reveconstudies.bsky.social

I've been a journalist for 25+ years and I'm not sure I've witnessed as much wilful (and v likely coordinated) disinformation from certain corners of the UK media than over past few days. Sun, Mail and Telegraph have been truly awful - and seemingly shameless www.theguardian.com/business/202...

But wait... There's more! Did those who received cash get lazier and work less? Nope! "We find no evidence that people love doing nothing. This stereotype is not supported by research on basic income – or any other research."

BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency. Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

Right on cue, the WSJ reports oil and gas lobbyists are asking Congress to grant Big Oil immunity against climate lawsuits. www.wsj.com/business/ene...

Spoiler: oui, à 256€ la tonne de CO2, il est rentable d'investir dans une pompe à chaleur. Heureuse d'avoir contribué modestement à cette commission sur la valeur de l'action pour le climat, valeur utilisée pour les décisions publiques d'investissement, mais aussi apparemment par qq entreprises !

That's really bad. EPA classification of GHG as harmful pollutants is pretty much the only way the US government can be held accountable on reducing GHG emissions. It's the legal framework justifying every piece of US emission regulation since 2009, on coal plants, passenger vehicles, etc.

A gentle reminder: we have failed to enact the single most ambitious, best-case scenario for emissions. All of the rest remain up for grabs: and we will absolutely 'fail to stop' these as well, if we widely adopt the fatalist framing

While the (quasi-) experimental methods increase credibility of causal results, there are two related concerns that make studies hard to replicate: 1. decline in reporting of null results 2. increase in use of private sector data a mini thread 🧵based on work with @trfetzer.com

I don’t know exactly what the response to this is, but I find it terrifying.
