Raghuram Rajan (FT) posed an interesting Q. yesterday (although not quite in these terms):

Are responses to #climatecrisis often #collectiveaction problems?

Do actions by one country that seem sensible actually undermine other countries' efforts to repose to #climatechange?

His example: #green policies that effectively reduce the ability of developing countries' firms to access rich-country markets & so reduce resources in the former to respond to climate change or shift to new activities.
