To help customers shop for groceries with lower carbon footprints, Danish supermarket Netto has started labelling climate-friendly options. A cloud icon on shelf labels indicates which items are least harmful when it comes to CO2 emissions.
Netto is labelling two sets of products that score highest when it comes to being green: the top 25% overall, and the top 25% of products within a given category. For example, meat might not be in the top 25% overall, but within the meat category, certain options are better than others. Labelling is based on a database compiled by green think tank CONCITO, which has mapped the climate footprint of 500 foods, allowing them to be compared across categories.
