The power of one! GlobalCool. What’s your number? We are all familiar with these slogans and the advertising campaigns urging us to calculate our carbon footprint. That is, the amount of greenhouse gases (GHG emissions) we emit into the atmosphere on an annual basis.

Our carbon footprint is calculated in equivalents to carbon dioxide or kg CO2e/kg. We already know that to reduce our footprint we should turn off lights, reduce air travel, choose public transport and ensure our home is properly insulated.

But can we make a difference with the food that we choose to eat? Recent studies suggest we can, and seafood appears to offer the most carbon efficient means to do so.
