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

Green Car Congress

This new study is based on a thorough review of a decade of research on aviation emissions. 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.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. There is an obvious link between environmental impacts estimated by life-cycle impact assessments and water quality problems described at the regional scale. Source: “Assessing Biofuels”.
