Carbon offsets have become a way for the environmentally conscious bourgeoisie to reconcile their values with their desire for McMansions and trips to the tropics. It's not clear whether carbon offsets really reduce emissions or are just a way for organizations to get some extra money out of projects that would have happened anyway. Regardless, the best animal-welfare organizations may be competitive with carbon offsets.
Per capita emissions from food in UK (metric tons CO2 equivalent) 2.7
Annual reduction from a vegetarian diet (tons CO2 equivalent) 0.59 (ibid.)
Cost of a vegetarian-year $11 US
Cost of preventing a ton of CO2-equivalent emissions $18.52 US
Cost of a metric ton of carbon offsets
Carbon Fund: $11.00 US
Terrapass: $13.09 US
One of Brian's essay's includes a higher estimate of what a non-meat (vegan in this case) diet prevents in greenhouse-gas emissions (the link to the study that provided the figure is dead). A vegan diet doesn't prevent much more GHG emissions than a vegetarian one, so the discrepancy may be due to differences between the UK and US or the authors' methods. If we use the 1.5 tons/year figure, the cost of preventing a ton of CO2-equivalent emissions falls to $7.33.
Vegetarians on average create more vegetarians, while carbon offsets don't create more carbon offsets. And I think the estimates also ignore people who reduce meat consumption. So donating to the Humane League may be a more effective way of reducing emissions than buying carbon offsets. Of course, there could be some problems with the survey data that we don't know about.
I wonder whether there's any way for animal-welfare organizations to attract environmentalists' dollars without changing the message. Lobbying and activism are probably more effective at preventing GHG emissions than buying carbon offsets, so animal-welfare organizations couldn't compete with environmental organizations directly. But GHG reductions would at least be a factor in their favor.
