The most eco-friendly barbecue fuel

Here's a fun article in Slate on whether gas or charcoal grills are better for the environment. Money quote:

If you're concerned solely with the carbon dioxide that wafts off your grill, then gas is the easy choice. But if you step back and consider the whole production cycle, then certain types of charcoal may well be the greener cooking fuel. The real trick, as is so often the case, is to select a product that's been created conscientiously—a tough assignment, given how little information manufacturers typically provide.
