First look at how their campaigns are funded. You will not find any meaningful action from politicians who are dependent on support from billionaires or powerful corporations. Then I would look at whether they are committed to supporting the Green New Deal and how their policies are rated by climate groups like the Sunrise Movement. This has helped me learn more about climate policy in general, and has made me more able to distinguish platitudes from serious proposals to address this crisis.

My favorite writer on the subject is Naomi Klein. I think her work is a good resource for learning more about the politics of the climate crisis.
