Thanks, Pat. Readers interested in air pollution may want to check Founders Pledge’s report on it. They do not have cost-effectiveness estimates, but I guess the best marginal interventions to decrease air pollution are less than 10 times as cost-effective as GiveWell’s top charities, whereas I estimated corporate campaigns for chicken welfare are 1.44 k times as cost-effective as those. So I think it is quite safe to say that the best marginal animal welfare interventions are more cost-effective than the best marginal air pollution interventions.
