European Parliament calls for fast action to cut non-CO2 climate forcers

Green Car Congress

The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.
