Abstract

Assembly Bill 32 (AB 32), the Global Warming Solutions Act of 2006, requires California to reduce its greenhouse gas emissions to 1990 levels by 2020, representing roughly a 25% reduction compared to business as usual. In this note, I summarize and discuss the key assumptions of a number of economic models estimating the costs of AB 32. Despite ignoring many of key benefits of AB 32, the model suggests the costs of AB 32 are likely to be small.

Keywords

costs of AB 32, climate change legislation, economic models of AB 32
