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.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

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. Reducing tropospheric ozone can improve public health as well as agricultural productivity.

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.

Study: Hydrofluorocarbons Will Contribute Significantly to Global Warming by 2050

Green Car Congress

Global ozone-depleting substances (ODSs) and HFC emissions (A), global CO 2 and HFC emissions (B), and ODS, HFC, and CO 2 global RF (C) for the period 2000–2050. These HFCs, gases used in refrigerators and air conditioners, are substitutes for ozone-depleting gases, but they are also strong greenhouse gases. The 1987 Montreal Protocol—restricting the use of ozone-depleting substances—helps both to protect the ozone layer and to reduce global warming.

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). Tropospheric ozone.

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.

US Climate Action Report to UN Projects 4% Growth in Total US GHG Emissions to 2020

Green Car Congress

A large portion of missions growth is driven by HFCs, because demand for refrigeration and air conditioning is increasing and because HFCs are predominantly used as alternatives for ozone-depleting substances, which are being phased out under the Montreal Protocol. Micronesia, for one, is proposing the use of the Montreal Protocol treaty to phase out HFCs as the most important fast-action strategy for saving their island.
