EVs beat petrol cars on lifetime emissions — even on “dirty” grids.
Battery production is carbon-intensive, but EVs quickly repay that debt and end up 21–71% cleaner over 250,000 km.

We can’t wait for perfect grids: electrify transport and clean the grid now.

It's very important that prospective home buyers and tenants have information about the climate risks of where they are considering moving. It's a real setback to climate adaptation that this information is being removed from Zillow. FEMA flood maps cannot be relied upon. bit.ly/4op4Vsw

This new study shows the risk that flooding worsened by climate change poses to toxic sites. As I wrote in 2023, the U.S. regulatory system is ill prepared to deal with this threat, but there are ways the laws can be changed to address it. bit.ly/4igwWRG

As I describe in detail in my new article in the New York Law Journal, the Trump administration has taken an all-of-government approach to squelching wind and solar.

Climate victory: NY court rules that State Dept. of Env. Conservation must issue its GHG cap-and-invest rules, as required by NY Climate Leadership & Community Protection Act, by Feb. 6. DEC was ready to issue the rules but Gov. Hochul stopped them. Next question: Will they appeal?
