The Environmental Defense Fund developed this report on current conditions and practices of underground gas storage (UGS) in the United States and China with a forward-looking perspective on key elements needed to develop a more comprehensive UGS regulatory program. UGS is key to an effective and reliable gas supply providing operational flexibility to meet an ever-changing supply and demand, notably when supply may be curtailed due to natural or geopolitical reasons. Critical to UGS is a robust regulatory program addressing all phases of operation for the protection of environment, human health and safety.

Helicopter surveys indicate malfunctioning flares in the Permian Basin are releasing at least 300,000 metric tons of unburned methane a year.

EDF is seeking a suitably qualified technology and services provider to work with EDF's Smart Boat Initiative and the Oregon Department of Fish and Wildlife to design, implement and test a "smartpass" camera system that is capable of identifying and enumerating recreational fishing vessels leaving and returning to ports in Oregon.

Our travel leaves a trail of carbon footprints. Fortunately, you can lighten your travel impacts on the climate in three simple steps.

Scientific paper built on European Space Agency data shows oil and gas production in America’s sprawling Permian basin is releasing methane, a potent greenhouse gas, at a 15 times higher rate than targets set by global producers including Shell and BP.

The Journal of Science Advances found that oil and gas operations in the Permian Basin are releasing methane at twice the rate of other U.S. regions.

Study demonstrates the potential for space-based data to drive down global methane loss rates
