What's the Carbon Footprint of Cycling a Mile?

(Guardian article here).

"Two people cycling along using energy from cheeseburgers is equivalent to those same people sharing a ride in an efficient car."

"Powered by biscuits, bananas or breakfast cereal, the bike is nearly 10 times more carbon-efficient than the most efficient of petrol cars."

"Bananas are brilliant, largely because they are grown in natural sunlight (no hot-housing required) and because they keep well, which means that although they may be grown thousands of miles from the end consumer, they are transported by boats, which is a hundred times better in terms of emissions than air-freighting. As a bonus there is hardly any packaging, if any, because bananas provide their own."

The carbon footprint of cycling a mile:
65g CO2e: powered by bananas
90g CO2e: powered by cereals with milk
200g CO2e: powered by bacon
260g CO2e: powered by cheeseburgers
2800g CO2e: powered by air-freighted asparagus
