Eric Crampton Oct 09, 2018

New Zealand has an emissions trading scheme. It isn’t perfect.

Net-zero carbon emissions: a “massive economic boost”? - The Dismal Science

Michael Reddell Aug 06, 2018

James Shaw, co-leader of the Green Party and Minister for Climate Change (surely Minister against it?), tells us he is working his way through 15000 submissions on the recent climate change consultation document.  I’ve done a couple of posts here on the document, and on the NZIER modelling used extensively in it, and I’ve chided both the Minister … Read More
