Scientists from Princeton, Stanford and Ohio State universities, as well as the Lawrence Berkeley National Laboratory, have identified the specific attributes of abandoned wells that leak significant amounts of methane, which could help state governments prioritize which wells to repair.
New research indicates that the Chinese government could dramatically improve air quality with more attention to an overlooked source of outdoor pollution — residential cooking and heating.
Princeton University researchers have uncovered a previously unknown, and possibly substantial, source of the greenhouse gas methane to the Earth's atmosphere.
Denise Mauzerall combines science and policy in analyzing the effects of air pollution on climate change, human health and agricultural production. She has emerged as a leader in using atmospheric models to track the flow of pollution, helping to identify where reductions of harmful emissions would have the largest benefit.
