In addition to cutting anthropogenic methane emissions, we must reduce atmospheric methane levels, which are at record highs and rising quickly (relatively more quickly than carbon dioxide and other greenhouse gases). The strongest approach to reducing methane levels is to couple cutting current and future emissions with removing methane that has already been emitted from the atmosphere. Methane Action works to evaluate methane removal technologies according to safety, effectiveness, equity, scalability, affordability, and other vital considerations, and to advance best governance practices for methane removal. Scientists in our networks are researching several potentially scalable methane removal technologies.
Methane Action’s goal is to cut atmospheric methane in half, restoring it to pre-industrial levels, within a decade. To achieve this, we are exploring a variety of methane oxidation methods. Examples include enhanced atmospheric methane oxidation (EAMO) using iron additives, adding zeolites to direct air capture facilities or using photocatalysis whether in large scale solar chimneys or in more scalable devices. We’ll post information about these and other approaches as it becomes available.
Developing such methods could change the methane math, transform current projections, and also equip us to deal with the possibility of a methane “burst.”
Methane Action’s mission is unique. We are the only NGO with the goal of rapidly advancing technologies for removing atmospheric methane. To that end, we also support deep reduction in methane emissions, to which atmospheric methane removal is a necessary complement.
