Thanks to renewable power expansion, fuel-importing countries saved more than $1.3tn between 2010 and 2023 that would otherwise have been spent on fossil fuels from overseas. Important contribution from @iea.org to current debates!

Une terrible nouvelle! Personnellement il me semble que ça va contre le “sens de l’Histoire”.

Encore plus personnellement je vais amèrement regretter cette ligne dans mes transits réguliers entre l’Ukraine et la France (en train c’est top)

Ouf: Reste le train de nuit Vienne-Bruxelles

Finally, a recent working paper, looking at the trade-off between the timing of climate action and the perfect allocation of action across sectors. It shows that timing dominates: in general, one should not delay action to enhance allocation across sector. documents1.worldbank.org/curated/en/0...

The report highlights all the potential benefits from a more coordinated approach across countries, to maximize the positive effects (eg, access to green technologies) and minimize the negative ones (eg, excluding poor countries from trade).

It shows that every 10% increase in income reduces the number of people living at high risk from climate hazards by 100 million. Overall, development reduces vulnerability, for any metric.
