North American Countries Target “Super” Greenhouse Gases Through Strengthened Ozone Treaty

Green Car Congress

The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. The Federated States of Micronesia submitted a similar proposal on HFCs as well. HFC emissions controlled under the Kyoto Protocol would not be affected by either the North American or Micronesia proposal.

New international Climate and Clean Air Coalition to focus on reduction of short-lived climate pollutants

Green Car Congress

Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near-term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F), The initiative of developing and developed countries was catalyzed by the Federated States of Micronesia as a way to slow sea level rise. The United States is already actively engaged in efforts to reduce these pollutants on the national and international levels.

Indo-US task force to study HFC phase-down

Green Car Congress

HFCs are chemicals are potential substitutes for ozone-depleting and climate-warming CFCs and HCFCs currently being phased out under the Montreal Protocol treaty to protect the ozone layer. Although they don’t harm the ozone layer, HFCs are powerful climate warming gases and their emissions are expected to rise sharply over the next few decades without aggressive action, significantly contributing to climate change.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

A “fast-action” climate agenda including reducing non-CO 2 climate change agents such as black carbon soot, tropospheric ozone, and hydrofluorocarbons (HFCs), as well as expanding bio-sequestration through biochar production, can forestall fast-approaching abrupt climate changes, according to Nobel Laureate Dr. Mario Molina (Chemistry, 1995) and co-authors in a paper published in the Proceedings of the National Academy of Sciences (PNAS).
