Hooray! The logic behind switching from buying offsets to focusing on efficiency goes far beyond what Yahoo touts in the article.

Instead of spending money on offsets, that you hope will do some good, spend that money on those green measures you cannot justify from a cost-savings perspective alone. Spend the money on healthier products, post-consumer recycled content products, or employee training. Our analysts at BlueMap, a sustainability research firm, always explain to clients that 'if you have money to spend on an environmental cause, spend it improving internally, do not give it away and hope for the best.'
