As China mines more coal, levels of a more potent greenhouse gas soar

By Christian Shepherd Photo: Qilai Shen , Bloomberg News

When China ramped up its reliance on coal-fueled power plants over fears of an energy crunch, climate experts were already worried, but now a study shows that the renewed mining will boost levels of methane, a greenhouse gas even more potent than carbon dioxide.


Supreme Court allows Biden climate regulations while fight continues

The Supreme Court on Thursday allowed the Biden administration, for now, to use a higher estimate for the societal cost of rising greenhouse gases when federal agencies draft regulations.


Supreme Court Allows Greenhouse Gas Cost Estimates

Louisiana and other Republican-led states challenged a federal working group’s efforts to develop standards for agencies to use in quantifying the harms caused by emissions. …


Gas wells leak explosive levels of methane in Bakersfield

State and regional inspectors found concentrations of methane in the air around some of the wells at levels considered potentially explosive and environmental activists in the region are worried that other chemicals may also be leaking from the wells that could pose a threat to public health.


Could Google’s carbon emissions have effectively doubled overnight?

Levels of carbon dioxide in the atmosphere reached the highest levels on record for any calendar month during April, averaging 420 parts per million (ppm) for the first time since observations began in 1958, according to new data.


Low-producing U.S. oil wells account for half of methane emissions, report says

By Valerie Volcovici Photo: Andrew Kelly

Low-producing oil and gas wells that account for just 6% of total U.S. production account for half of the methane emitted from all U.S. well sites. The study, published in Nature Communications, is the first to take a comprehensive look at the over 560,000 active “marginal” oil and gas wells across the United States that account for 80% of all well sites. It comes as the Environmental Protection Agency prepares to unveil new provisions for its methane regulation for the oil and gas sector that it introduced last November.


Study: Low-producing oil wells cause 50% of methane emissions

Low-producing oil and gas wells are to blame for roughly half of the methane emitted from all U.S. well sites, despite making up 6 percent of the country’s total production, according to new research published this week. The study, published in Nature Communications, is the first comprehensive look at low-production well site emissions nationwide, researchers said. The paper found that low-producing or “marginal” wells emit methane at a rate 6 to 12 times higher than the national average — releasing some 4 million metric tons of the potent greenhouse gas a year.


Methane emissions from US low production oil and natural gas well sites

By Mark Omara, Daniel Zavala-Araiza and Others

Mitigation of methane (CH4) emissions, a powerful greenhouse gas with >80× the 20-year warming potential of carbon dioxide is widely recognized as strategically integral to the attainment of the climate-neutrality goals of Paris Agreement. In the United States, official estimates from the US Environmental Protection Agency (EPA) indicate nearly one-third (30%) of anthropogenic CH4 emissions arise from oil and natural gas (O&G) operations.


FERC pipeline policy compromise could kill climate-based veto authority

By Catherine Morehouse Photo: Keith Srakocic , AP

FERC commissioners’ effort to strike a compromise on a new policy framework for pipeline certifications may put pressure on the Democratic majority to make concessions about whether a project’s greenhouse gas emissions can derail its approval, according to energy experts.
