I'm keen on saving the planet but a little sceptical about some of the claims in this article.  Yes companies with low carbon emissions may be outperforming other companies but which is causing which?  Might it be that a high performance company can better afford to invest in low carbon projects?  Some projects may have fantastically quick paybacks but I have seen plenty of green projects - recycling especially, that benefit emissions but not the bottom line.
