US cities working to reduce emissions in the absence of bold action in Washington

But fewer than half of the 100 largest cities have plans to tackle climate chaos

After the Cop26 conference ended in Glasgow, many activists and climate scientists felt the agreement didn't go far enough and that the US government was among those who had not backed strong words with enough actual deeds.

But action on a smaller level in the US - in cities and states - is gaining traction and beginning to make a significant difference. Smaller-scale initiatives to cut emissions have been the significant way that America has made climate progress in the last few years, in the absence of stronger federal leadership.
