Relating to technical background
In complement to anthropogenic methane emissions reductions, atmospheric methane removal has been proposed in order to: address methane sources difficult to prevent or avoid, deal with legacy emissions, remove increasing emissions from wetlands and water bodies induced by anthropogenic global warming, and prepare in case of a methane burst (rapidly thawing permafrost and catastrophic releases […]

Methane Action announced publication of a first-ever environmental impact modeling study of the potential methane removal technique known as Enhanced Atmospheric Methane Oxidation (EAMO). EAMO aims at oxidizing methane in the atmosphere and could potentially be used to lower dangerously high and rapidly rising methane levels. The study was published in the peer-reviewed science journal […]
Bob Howarth, Phd of Cornell University discusses the importance of methane emissions reduction in relation to New York State’s goal of converting to 100% renewable energy sources by 2050. Professor Howarth emphasizes why “natural gas” is not a “bridge fuel to the future” and why it is important to phase out methane as opposed to […]

This article reviews proposed methods for atmospheric methane removal at a climatically significant scale. These methods include enhancement of natural hydroxyl and chlorine sinks, photocatalysis in solar updraft towers, zeolite catalyst in direct air capture devices, and methanotrophic bacteria. Though these are still at an early stage of development, a comparison is provided with some […]

Abstract Mitigating climate change requires a diverse portfolio of technologies and approaches, including negative emissions or removal of greenhouse gases. Previous literature focuses primarily on carbon dioxide removal, but methane removal may be an important complement to future efforts. Methane removal has at least two key benefits: reducing temperature more rapidly than carbon dioxide removal […]
Abstract Atmospheric methane removal (e.g. in situ methane oxidation to carbon dioxide) may be needed to offset continued methane release and limit the global warming contribution of this potent greenhouse gas. Because mitigating most anthropogenic emissions of methane is uncertain this century, and sudden methane releases from the Arctic or elsewhere cannot be excluded, technologies for methane […]

Comments of Methane Action and Remineralize the Earth in response to the U.S. Environmental Protection Agency’s solicitation of public input on the Agency’s efforts to reduce emissions of methane and other air pollutants from the oil and natural gas sector. […]
Abstract Fulfilling the Paris Climate Agreement requires reducing rapidly the new emissions of greenhouse gases (GHGs) to reach net zero by 2050. As some anthropogenic emissions cannot be zero, to compensate them it will be necessary to remove GHGs from the atmosphere. Among possible methods, the Iron Salt Aerosol (ISA) offers new possibilities, including removal […]
