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. This new study is based on a thorough review of a decade of research on aviation emissions. The formation and emission of sulfate aerosol yields a negative (cooling) term.

PCC SE and Landsvirkjun to convert silicon metal plant CO2 emissions to methanol

Green Car Congress

Landsvirkjun , The National Power Company of Iceland, and German investment company PCC SE have agreed to explore the possibility of capturing and utilizing carbon emissions from PCC’s silicon metal plant in northeast Iceland. Carbon emissions will be utilized to produce green methanol that can, for example, replace fossil fuel in ships.
