The environmental footprint of eating meat has been studied recently with much more intensity. The general consensus is that meat-intense diets are responsible for more CO2 emissions than plant-based diets, although the exact amounts are still being debated. A recent study from the University of Chicago concluded that 'a person consuming a mixed diet with the mean American caloric content and composition causes the emissions of 1485 kg CO2-equivalent above the emissions associated with consuming the same number of calories, but from plant sources.'

In reality, Westerners, and especially North Americans, consume at least 10 times the meat per person compared to poor countries. This is not a sustainable level to maintain.

A reduction in meat consumption by 50% (say, to one meal per day) would have the effect of reducing almost 750kg of CO2 per year. This would be more than an equivalent reduction than walking to work instead of driving, for the average person.


The estimated impact each time this challenge is completed: 15 kg / 33 lbs CO2 reduced and saving up to $0!
All completions of this challenge have reduced approximately 12.83 tons CO2 and saved up to $0!
