"Why Wal-Mart and P&G are disclosing greenhouse emissions--and you should too."

I admit, it's getting harder to find a publication that does not have some green to it. But still it warms the very cockles of my heart when I see business magazines covering and recommending climate-conscious action. Fast Company, for instance, has a column by David Roberts, who also writes for one of the original environmental publications, now on the web, grist.org. In the Dec 07/Jan 08 issue, Roberts notes that more and more companies are disclosing their sorry status --GHG-wise, voluntarily. In part, it's to establish green cred, which is an increasingly valuable part of a company's brand equity. But it's also "because it's always better to know than not to know." Such companies -- at least a few hundred so far-- will be ahead of the game come the nearly certain carbon market, and increased regulations.

But Roberts' most powerful argument is that "carbon emission...[is] gaseous evidence of inefficiency. It costs money to create carbon dioxide, so cutting emissions slashes costs."
