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

Green Car Congress

From 2005 through 2020, total US greenhouse gas (GHG) emissions are projected to rise by 4% under a “with measures” scenario (but without a cap-and-trade program and other complementary policies), from 7,109 Tg CO 2 Eq. The report projects that transportation-related CO 2 emissions will drop 1.5% to 7,416 Tg CO 2 Eq., 5,813 Tg CO 2 Eq.

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

Green Car Congress

The initiative of developing and developed countries was catalyzed by the Federated States of Micronesia as a way to slow sea level rise. This may be the only way to reduce climate impacts in the near term, and is a critical complement to the primary battle to reduce emissions of CO 2. The results were published last month in Science.

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

Green Car Congress

Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences, the authors write.

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.
