Today’s chocolate problem: cow burps

Today’s snow storm has closed New York schools and cancelled my scheduled lecture on Staten Island.  This unexpected holiday gives me time to contemplate the latest challenge to marketers of chocolate candy: gas emissions from dairy cows.

Cadbury estimates that 60% of the carbon footprint created by its chocolate operations in the U.K. comes from dairy cows.  The average cow, it says, gives off 80 to 120 kilograms of methane annually, an amount equivalent to that produced by driving a car for a year.

The remedy?  Reduce cow burps.   How?  Cadbury is going to try feeding them more clover, more starch, and less fiber, and treating them better.

Will this work?  If it does, will you buy more Cadbury chocolate?
