1. California regulators are poised to roll back some diesel emissions rules because of the recession and errors made calculating air pollution, California Watch reports. Next week, the state Air Resources Board will consider easing regulations for off-road construction vehicles, noting that a new analysis shows that there’s 80 percent fewer diesel emissions statewide than previously thought. About half that amount is due to the recession and the collapse of the construction industry. But environmentalists and health advocates contend the proposed rule changes will foul the air and snuff out the growing clean-tech emissions industry.
