An exacting complainant caught out an electricity firm over its claim to be 100 per cent green.

The Advertising Standards Authority (ASA) has slapped down Crawleybased Seeboard for a direct mailing it said was "100 per cent environmentally-friendly".

The mailing could be recycled, contained no stapes or glue, and was made from paper containing 80 per cent recycling fibres.

But a complainant argued energy had been used to make and deliver the mailing.

The ASA stated: "The claim '100 per cent environmentally-friendly'

implied the mailing would cause absolutely no environmental damage throughout its life-cycle.

"Because the advertisers had not shown that was the case, the authority concluded the claim was exaggerated."

Seeboard has been asked to amend the claim.
