Releases of methane, a short-lived but strongly warming greenhouse gas, from sources including wetlands, inland waters, agriculture and fossil fuel systems.
Penn State researchers estimate that about 2% of the natural gas piped into Indianapolis leaks, based on nearly a decade of tower data. They say most of it likely comes from homes and other buildings, not exterior pipelines.
Reality
Johns Hopkins researchers estimate US oil and gas methane stayed within 9.3 to 10.4 teragrams a year from 2019 to 2024 as production rose. They found no detectable drop after the Inflation Reduction Act. The pipeline explanation is hedged.
Reality
A paper in Environmental Research Letters estimates that permafrost, wildfire, wetland and inland-water emissions amplify human-caused warming by 20 to 30 percent, though at one standard deviation the low-emissions case still runs from zero to 0.4 C.
Reality
Tanager-1 logged 1,097 methane plumes across the Permian, Appalachian and Haynesville basins between January 2025 and June 2026, and researchers matched about a third of them to a named operator using public Carbon Mapper data.

The framework, produced with Green Futures Solutions at the University of Exeter for Earthshot Prize judging, asks whether a solution's economics improve as it spreads, and it attaches a 2030 target to each area.
