There are several ways that one could remove atmospheric methane, one being atmospheric oxidation enhancement <https://www.sparkclimate.org/methane-removal/primer/approaches> (AOE). This involves introducing materials into the atmosphere to increase the oxidation of methane. The most researched approach involves iron salt aerosols <https://www.sparkclimate.org/methane-removal/primer/approaches/iron-salt-aerosols>, which catalyze the formation of chlorine radicals to oxidize methane. There are many similar challenges between AOE and SRM, including measurement and verification, social acceptance, and cross-border governance.
Spark's webinar series discusses different aspects of methane removal, in this webinar we talk through one of the factors that motivates our work on this topic.
