There are numerical errors in the first two sentences of the “Policy Implications” heading under the Results and Discussion section. The correct sentences are: We found that for a moderately stringent, highly flexible policy scenario similar to the final U.S. Clean Power Plan, the monetized value of health co-benefits alone exceed estimated costs for the U.S. by $12 billion per year in 2020. When the social cost of carbon is included, the benefits increase from $29 billion to $50 billion with national net benefits of $33 billion per year in 2020.
