Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot.

While carbon dioxide is the primary driver of global warming over the long term, limiting black carbon and methane are complementary actions that would have a more immediate impact because these two pollutants circulate out of the atmosphere more quickly.

The report also covers an assessment of the potential contribution from reductions in short-lived climate pollutants (SLCPs). Avoiding new coal-fired power plants and accelerated phasing out of existing plants—while ensuring careful handling of issues such as employment, investor interests and grid stability—would help the emissions picture. There are an estimated 6,683 operating coal-fired power plants in the world, with a combined capacity of 1,964 GW.
