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

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. The study was published in the journal Atmospheric Environment. Here, we present a new comprehensive and quantitative approach for evaluating aviation climate forcing terms.

The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Deterioration of the ozone layer [kg CFC-11-eq.]. Eutrophication of non-marine aquatic environments [kg N-eq.]. Eutrophication of non-marine aquatic environments [kg P-eq.].

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.

in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol. Because of the enormous potential impact of these products, reducing their emissions has a disproportionate benefit to the environment.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases.
