POLL: Has carbon offsetting had its day?

Thinking back to when I first heard about the concept of carbon offsetting, I remember thinking that while it seemed like a lovely idea to absolve your eco sins by adding some scenic foliage to the world, it all seemed a bit too good to be true. I wanted to believe, but it wasn't long before the doubts started to be expressed by those with more of a grasp on the science, I knew it was only a matter of time before carbon offsetting began to sound at best quaint, and at worst, crazy.

A story in the Guardian's Ethical Living Blog gives even more reasons to be sceptical about carbon offsetting, and frankly, I'm sold. But am I being defeatist? Let me know your views on carbon offsetting in by voting in the poll below.
