Pricing superpollutants: The economic case for cutting methane and near-term climate pollution

This EDF post argues that carbon dioxide is not the only pollutant that needs a price. Superpollutants like methane and hydrofluorocarbons cause a large share of near-term warming, but they are often left out of carbon pricing systems. The author explains why putting a price on these short-lived climate forcers could deliver faster climate benefits than focusing only on CO2. The piece breaks down the economics: because superpollutants have a much higher warming potential per ton but a shorter atmospheric lifetime, pricing them differently makes sense. The article also looks at how existing cap-and-trade programs and carbon taxes could be expanded to cover these gases, and what barriers stand in the way of implementation. For anyone following carbon market design or methane regulation, this is a useful read. It connects the dots between climate science and market mechanisms without getting lost in theory.
