Beyond mitigating emissions, what else can be done to reduce atmospheric methane levels?

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 do two things: cut methane emissions wherever we can, and where we can’t, remove emitted methane 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, rapidly restoring it to pre-industrial levels we assume to be safe.  To achieve this, we are exploring a variety of methane removal methods. Examples include adding zeolites to direct air capture facilities, using photocatalysts in large scale solar chimneys or in more scalable air moving devices, and enhanced atmospheric methane oxidation (EAMO) approaches which work with and accelerate the natural process of methane oxidation in the atmosphere. We’ll post information about these and other approaches as it becomes available.

Developing such methods could change the methane math, transform current climate 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 are also committed to deep reductions in methane emissions, to which atmospheric methane removal is a necessary complement.  Both emissions reduction and methane removal are mission-critical for lowering atmospheric methane concentrations to safe levels.
