Before going any further here, I want to make it clear that I’m well aware of the shortcomings of carbon offsetting, wonderfully satirised by the folks behind Cheat Neutral. However, carbon offsetting is undeniably better than doing nothing. And as sustainable as you might try to be, it probably isn’t enough. The World Resources Institute have calculated that we should be aiming for a maximum limit of two tons of CO₂ emissions per person, per year. And yet it is calculated that the average EU citizen incurs 9.1 tons of CO₂ emissions. The average US citizen emits about twice as much as this.
