A guide to the green labels and logos on products in shops, published by Defra, includes details about both the Programme for the Endorsement of Forest Certification (PEFC) and Forest Stewardship Council (FSC) schemes in its timber products section.

The pocket-sized guide shows the environmental labels shoppers are most likely to come across – and explains what they mean.

Environment minister Elliot Morley said: “Individual consumers have a vital role to play when they are choosing which goods and services to buy.

“Some products really are more environmentally responsible than others – but it can be difficult to know which ones.

“A lot of companies use environmental labels and claims in one way or another as evidence of their commitment to the environment, and we certainly encourage them to provide information that’s relevant and reliable.”

But, he said, consumers needed to know what the labels meant and what claims they could trust – information spelled out in the guide.
