Superpollutants — methane, nitrous oxide, and legacy refrigerants — are responsible for roughly half of all observed warming since the Industrial Revolution. Some are 13,000 times more potent than CO₂. And because they clear the atmosphere in years, not centuries, reducing them today produces faster climate results than almost anything other action or asset in a corporate program.

This guide covers what superpollutants are, how carbon markets address them, what procurement looks like across four project types, and where they fit in SBTi's new Ongoing Emissions Responsibility (OER) framework.
