This document compares the carbon dioxide emissions of hybrid cars, eating apples and croissants, and following a vegan diet. It estimates that driving a hybrid instead of a non-hybrid would reduce carbon dioxide emissions by 360 tons per year. It also estimates that eating apples instead of croissants would reduce emissions by 14.4 tons per year based on consumption of 200 people. Finally, it estimates that following a vegan diet would reduce emissions by 619 tons per year compared to the average diet based on differences in average kilometers traveled per year.
