Berkeley Lab scientists develop new method for evaluating short-lived pollutants.

New research from Lawrence Berkeley National Laboratory (Berkeley Lab) has found that levels of methane—a potent greenhouse gas emitted from many man-made sources, such as coal mines, landfills and livestock ranches—are at least one-and-a-half times higher in California than previously estimated.

Working with scientists from the National Oceanic and Atmospheric Administration (NOAA) Berkeley Lab scientists Marc L. Fischer and Seongeun Jeong combined highly accurate methane measurements from a tower with model predictions of expected methane signals to revise estimated methane emissions from central California. They found that annually averaged methane emissions in California were 1.5 to 1.8 times greater than previous estimates, depending on the spatial distribution of the methane emissions. (more…)

AUSTIN, Texas — A report from the Massachusetts Institute of Technology (MIT) and The University of Texas at Austin urges the U.S. to accelerate efforts to pursue carbon capture and storage (CCS) in combination with enhanced oil recovery (EOR), a practice that could increase domestic oil production while significantly curbing emissions of carbon dioxide (CO₂).

For decades the oil industry has used CO₂ to extract oil from mature fields, often relying on purchased CO₂ from natural sources. The idea of seeking CO₂ from industrial sources, such as coal- and natural gas-fired electricity plants, has gained currency because of public concerns about carbon dioxide emissions. (more…)
