Biden unveils new US emissions targets: comment

"This is great ambition for the next four years, given who is taking office; it would have been better if this had been the sort of level set for 2030, which would align it with 1.5°. But over the next four years, we’re likely to see states, cities, companies, organisations and citizens in the US step up and say that they’re still in the Paris Agreement. So if they make progress towards delivering this NDC, then they will ensure Trump fails again this time around, as he failed last time to slow climate action or disrupt international climate talks."
