Sometimes what’s bad for the economy can be good for the planet. Or so argued Lester Brown, president of Earth Policy Institute, yesterday. This environmental trend spotter pointed to several developments that may have escaped our attention as the global economy alternately sputtered and entered periods of freefall throughout the past 18 months. Trend one: U.S. emissions of carbon dioxide, a leading greenhouse gas, have taken a tumble.
