Leave it to the brainiacs to ruin a perfectly good thing. Jamais Cascio, author of the blog Open the Future, has determined the carbon footprint of a cheeseburger and you're about to feel really guilty.
At 2.85-3.1 kg of CO2 (equiv) per burger, then, that's 428-465 kg of greenhouse gas per year for an average American's burger consumption.
...adding in the methane, the overall CO2-equivalent emissions from all the cheeseburgers consumed in the US (assuming the average of 3/person is accurate) roughly equal the greenhouse output of 100,000 SUVs.
Well, that's depressing. Of course, there are well over 100,000 SUVs on the road, so if we could just convince 100k SUV-owners to use public transportation then we can eat with a clear conscience.
