Our new paper is out in Climatic Change, co-authored with (the amazing and wonderful) David Krantz (Columbia University) and Elke Weber (Princeton University).
We find that people are more likely to support decarbonization policies if the advocate for the policies have a low carbon footprint. We also find that the negative effects of a large carbon footprint on credibility are greatly reduced if the communicator reforms their behavior by reducing their personal carbon footprints.
