Carbon footprint: but yes, we can easily eat bananas!. Mike Berners-Lee is the pioneer of carbon counting.
A banana: 110 g of CO2; one kilo: 670 g. The average message, ten seconds of writing, five seconds of reading, so the total footprint is 3 kg per person per year. “Even though they represent more than half of the messages, they only represent 2% of the total carbon footprint,” says the Englishman.
