Lithium-ion batteries contain large amounts of valuable materials such as lithium, cobalt, nickel and copper. By design, those batteries are ≈95% recyclable, yet less than half is currently being recycled. A few thoughts on why that is, and why it should change.

The next European energy crisis could come from extreme climate events, rather than geopolitics. Intensifying droughts, floods, and water shortages put energy systems under pressure. Investments are required to make infrastructure more resilient and avoid widespread disrputions and blackouts.

I sat down with Quartz to discuss the implications of BYD's rollout of autonomous driving features to its mid-tier and entry-level EVs at no extra cost. Read it here: qz.com/byd-tesla-go...

About half of all water supplied by utilities gets lost, primarily because of leaks across networks. This number keeps getting worse every year, and so do droughts and water scarcity. Water network modernization can no longer wait.

Water pollution is an often overlooked aspect of coal use. Burning coal releases mercury into the atmosphere, which eventually returns to the ground with rainfall. In the EU, 70% of surface water is contaminated by chemical pollutants; without mercury from coal, this figure would drop to just 20%.

Reinsurance data offers one of the best proxies of the worsening climate crisis. This chart shows the evolution of insured losses related to natural disasters - from almost none, to a significant amount every year.

The EU ETS continues to succeed. In 2023, sectors targeted by the scheme saw reduced their emissions by 16.5% in 2023, while generating €44bn revenue to support climate action among members states. See the full 2023 report published today: climate.ec.europa.eu/document/dow...

Rich nations should rather put their own house in order. Yes, China's emissions are high - because they support a 1.4bn population and the manufacturing of a third of global goods. Yet, per capita, they emit 30% less than the US and are moving away from fossil fuels at a faster pace.

I knew insurers were early in understanding climate risks, but I didn’t realize just how early. This text, highlighting CO2’s role in climate change, comes from a 1973 (!) paper by Munich Re.

Sharp disconnects between the level of noise, and the level of impact are often the sign of lobbies at play. CCUS is a good example: lots of noise, for a technology that currently captures ≈0.1% of global emissions, and will rise to ≈0.5% if all planned developments go through.
