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 warming from NO x emissions is a sum over warming (short-term ozone increase) and cooling (decreases in methane and stratospheric water vapor, and a long-term decrease in ozone) terms. Aviation accounts for 3.5% Pitari, M.J. Prather, R. Sausen, L.J.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. Because of the enormous potential impact of these products, reducing their emissions has a disproportionate benefit to the environment.

Study Finds Traveling by Car Increases Global Temperatures More than Traveling by Plane In the Long Term

Green Car Congress

Global average values for the year 2000. The researchers used a suite of climate chemistry models to consider the climate effects of all long- and short-lived gases, aerosols and cloud effects, not just carbon dioxide, resulting from transport worldwide. Car travel emits more carbon dioxide than air travel per passenger mile.
