To put the study in perspective, driving a single mile in your car will emit the same amount of CO2 as brewing 8 of the least efficient cups of coffee listed in the study, and using a single gallon of fuel emits 360 inefficient cups worth of CO2[0].

So basically if you want to ‘offset’ a years worth of daily coffee, drive approximately 20-30 less miles per year.
