We do not just rate products, we rate brands and retailers.

We do rely on published information and do not undertake primary research.

We stick to the major schemes & labels and verify, as far as possible, a company's green claims.

We also have own rules, for example where information is poor or absent.

We do make our own independent assessment based on a range of information sources produced by voluntary bodies, campaign groups, government, and industry bodies; we also look at how other schemes have benchmarked a company or brand.
