Consumers will soon be able to compare, buy and reject products based on their greenhouse emissions after the launch of a carbon footprint labelling scheme. Australia will be the third country, after Britain and the US, to get the foot-shaped Carbon Reduction Label, which is being billed as the greenhouse equivalent of a nutritional panel.

Professor Snow Barlow from the School of Land and Environment comments on the importance of the scheme for food security and best practice in standardising greenhouse gas emission reporting for food production.
