What should companies be required to disclose about their environmental impact?

Consumers hear countless claims:

sustainable, green, responsible, carbon-neutral.

Some are meaningful.

Others are difficult to verify.

What environmental information should companies have to make publicly understandable?

A claim is easier to assess when its boundaries are clear. Does it describe one product, a factory or the whole business? What period does it cover? Is the comparison like for like, and can someone outside the company check it? Useful disclosure should help people make decisions without requiring them to read hundreds of pages or accept a label on trust.

• Which claim do you find hardest to judge? • What evidence would help? • How should smaller businesses report proportionately?
