China, with its enormous cities and vast countryside, is a potential star in the ongoing global drama of slashing carbon emissions.

In this week’s Nature, a Michigan State University researcher and an international team of sustainability experts propose a script.

China already is a star in unleashing carbon dioxide emissions. In 2011, it accounted for a quarter of the world’s total. The problems – air pollution, squandered energy resources and economic stresses that squelch growth – also come with tremendous opportunity for China to be leader in slashing emissions. Along the way, China’s vast variety of economic and geographic circumstances offers a chance to set examples for its global neighbors. (more…)

Berkeley Lab Study Assesses Residential Cooking Exhaust Hoods’ Ability to Vent Pollutants

Cooking exhaust hoods designed for home kitchens vary widely in their ability to capture and vent away the air pollutants generated by the gas burners on cook stoves, according to a study by two Lawrence Berkeley National Laboratory (Berkeley Lab) scientists. Of seven representative devices they tested, the capture efficiency varied from less than 15 percent to more than 98 percent.

The study, by Woody Delp and Brett Singer of Berkeley Lab’s Environmental Energy Technologies Division, measured their pollutant capture efficiency, sound level generated by their fans, and airflow. Cooking exhaust hoods vent such pollutants as carbon monoxide, nitrogen oxides, formaldehyde, and fine particulates such as soot generated during cooking. (more…)
