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

Green Car Congress

The study was published in the journal Atmospheric Environment. Net positive RF (warming) contributions arise from CO 2 , water vapor, NO x , and soot emissions, and from contrail cirrus (consisting of linear contrails and the cirrus cloudiness arising from them). Aviation accounts for 3.5% Pitari, M.J. Prather, R. Sausen, L.J.

Ionic liquid-enhanced solvent extraction for oil sands bitumen shows high recovery rates, less water use and no tailing water

Green Car Congress

Canadian oil sands are a complex mixture of sand, clays, water, and bitumen. For surface mining oil sands production, a hot water extraction process (HWEP) has been widely applied. In this process, hot water and processing aids are mixed with oil sands to liberate bitumen from the minerals by shearing the oil sand particles.
