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

Green Car Congress

It makes an important contribution to the scientific understanding we have of the role of aviation for climate change—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement. This new study is based on a thorough review of a decade of research on aviation emissions.

ICCT study finds that transitioning to low-GWP MAC refrigerants in China could avoid up to US$150B in costs

Green Car Congress

Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs.

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) Emissions from normal operations include: natural gas engines and turbine uncombusted exhaust; bleed and discharge emissions from pneumatic devices; and fugitive emissions (leak) from system components.

Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships. 1 from shipping in 2007, corresponding to 3.3% 1 of the total ship emissions in 2007.

Geo-engineering could be ‘our only hope’

Green Cars News

The future of the Earth could rest on potentially dangerous and unproven geo-engineering technologies unless emissions of carbon dioxide can be greatly reduced, the latest Royal Society report has found. Geo-engineering and its consequences are the price we may have to pay for failure to act on climate change.”.

EPA issues greenhouse gas proposals

Green Cars News

According to the findings, the six key greenhouse gases - carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydroflurocarbons (HFCs), perflurocarbons (PFCs) and sulphur hexafluoride (SF6) - threaten the welfare of both current and future generations.
