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.

More Reflective Roofs and Pavements Could Help Offset Climate Emissions

Green Car Congress

Increasing the reflectivity or albedo of roofs and pavements in urban areas could offset greenhouse gas emissions by a significant amount, according to an open access paper published last month in the IOP journal Environmental Research Letters. —Menon et al.

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% US Fifth Climate Action Report.

California Air Resources Board adopts GHG cap-and-trade program; first auctions slated for Aug/Nov 2012

Green Car Congress

The California Air Resources Board on Thursday adopted the final greenhouse gas (GHG) emissions cap-and-trade regulation. The “cap” limits GHG emissions, and uses allowances—one allowance equals one ton of GHGs—to control total emissions. Compliance obligations for greenhouse gas emissions begins 1 January 2013.

California ARB greenlights states GHG cap-and-trade program

Green Car Congress

The “cap”—which declines each year—limits GHG emissions, and uses allowances to control total emissions; one allowance equals one ton of GHGs. Covered entities must reduce emissions or. compete for a decreasing supply of allowances.

What is the Electric Vehicle Approved (EVA) Scheme?

Green Charging

It is also the UK government strategy to achieve zero-emission by 2040. Global warming plays a role in thinning the ozone layer, thus permitting harmful rays’ penetration to the earth. Therefore, this organisation aims to decrease carbon emission by motor vehicles. Office for Zero Emission Vehicles (OZEV).
