Today in the dailyclimate@newsletters.dailyclimate.org,  Andrew Simms in the Guardian suggests that we take a deeper look into the economic models that show carbon pricing as a solution to climate change. Commenting on BP’s call for a “meaningful price on carbon” in the latest edition of its Statistical Review of Energy, he reminds us that it is not a given that price signals will result in less fossil fuel use. There are assumptions “buried” in economic models, and we need to know which are included and excluded from analysis before we accept a prediction.
