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

Green Car Congress

Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climate changes, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

Indo-US task force to study HFC phase-down

Green Car Congress

The global warming potentials (GWP) of HFCs range from 140 (HFC-152a) to 11,700 (HFC-23), according to the US EPA. Last year, the Federated States of Micronesia along with other vulnerable island countries proposed an amendment to the ozone treaty to phase down the production and use of HFCs.

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. Their contribution to global warming is currently small, but can increase to the equivalent of 9-19% (CO 2 -eq. Velders et al. 2009) Click to enlarge.

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

Green Car Congress

If accepted by the other Montreal Protocol Parties, the proposal would deliver climate mitigation equivalent to preventing more than 100 billion tonnes of CO 2 emissions. The Federated States of Micronesia submitted a similar proposal on HFCs as well. C, says IGSD. Durwood Zaelke. Durwood Zaelke. Mario Molina, Durwood Zaelke, K.
