Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. The study was published in the journal Atmospheric Environment. This new study is based on a thorough review of a decade of research on aviation emissions.

Urban CO2 Domes May Enhance May Increase Ozone and PM, With Accompanying Increase in Mortality

Green Car Congress

In a new study published online 10 March in the ACS journal Environmental Science and Technology , however, Stanford University professor Mark Jacobson finds that local CO 2 emissions in isolation may increase local ozone and particulate matter. Not all carbon dioxide emissions are equal. Jacobson, 2010. Mark Jacobson.

European Parliament calls for fast action to cut non-CO2 climate forcers

Green Car Congress

The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.

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. 5 014005 doi: 10.1088/1748-9326/5/1/01400.

WMO reports GHG concentrations at highest in 800K years

Green Car Congress

Emissions represent what goes into the atmosphere. About a quarter of the total emissions is taken up by the oceans and another quarter by the biosphere, reducing in this way the amount of CO 2 in the atmosphere. The WMO Greenhouse Gas Bulletin reports on atmospheric concentrations of greenhouse gases. This record annual increase of 3.3
