Friends of the Earth has published major new research which sets out the environmental impact of making the products we use every day. We want to live within the limits of what the planet can provide so first we need to measure what we are using. We asked environmental data experts Trucost to find out how much land and water is needed to make our food, our clothes and our gadgets - through the whole supply chain...And it’s a lot. A pair of leather boots could take 14 tonnes of water and 50m2 of land to make...We want companies to account for all the land, water, carbon and materials that are used in their whole supply chains, using the four footprints: Land, water, carbon and materials.
