Can ethical audits be credible?

Dear Sir,

Today’s UK/European lighting business would not survive without supplies from ‘the developing world’ – but the problem of verifying the ethical audits of factories is contentious, and has recently been highlighted in the press, including The Guardian.

So how do we go about producing a credible system of certification for companies committed to sustainable management, design and production ?

I ain’t got an answer but I’d love to hear from anyone with ideas or experience as to how the situation could be addressed.
