Potent GHG SF6 rapidly accumulating in atmosphere, driven by demand for SF6-insulated switchgear in developing countries

Green Car Congress

In an open-access study in the EGU journal Atmospheric Chemistry and Physics , an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6 ) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries.

Met Office Climate Scientist: “Apocalyptic Predictions” Of Climate Change Can Impede Understanding Of Long-Term Warming Trends

Green Car Congress

News headlines vie for attention and it is easy for scientists to grab this attention by linking climate change to the latest extreme weather event or apocalyptic prediction. But in doing so, the public perception of climate change can be distorted. This message is more difficult to get heard. Vicky Pope, Met Office.

Ford Becomes First Automaker to Join the Water Disclosure Project

Green Car Congress

Ford has reported to the CDP on its successful efforts to reduce its carbon footprint since 2003. Going forward, Ford has set a goal to reduce new-vehicle greenhouse gas emissions in the US and Europe by 30% by 2020, compared to a 2006 model year baseline. From 2000 to 2008, Ford cut its global water use by 56%, or 9.5

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Slightly more than half of the GHG emissions for these biofuels in the EPA’s analysis came from land use change. At those levels, palm oil biofuels do not meet the minimum 20% greenhouse gas (GHG) reduction compared to the statutory baseline for petroleum-based diesel performance threshold required for renewable fuel under the RFS program.
