Does every company - large or small - need to start looking at its environmental impact?

It's an issue which has hit the headlines with the launch of a major new CBI report on climate change.

It says British businesses are committed to doing what it takes to tackle climate change - but claims the UK effort will only succeed if it becomes a priority for companies, consumers and the Government working together.

And the CBI says climate change is a 'challenge' which every company should be taking seriously.

So what's being done in Wales to rise to the challenge? Do we need to do more? And is this necessarily a cost to business - or can it be an opportunity as well?
