Cadbury is to encourage its cows to burp less to reduce the carbon footprint of its milk chocolate.Article from Environment | guardian.co.uk last week.
Studies show that the production of one litre of milk produces the equivalent of 900g of CO2. More than half of this is down to methane. The average cow emits between 80kg and 120kg of methane a year, equivalent to the annual carbon emissions from an average family car.Maybe we should all switch to dark chocolate instead.
