GISS study finds applying stricter non-CO2 vehicle emission standards worldwide would yield climate benefits in addition to major health and agricultural benefits

Green Car Congress

Global and regional zonal mean temperature changes relative to 2010 due to non-CO 2. used global composition-climate modelling to examine the integrated impacts of adopting stringent European on-road vehicle-emission standards for non-CO 2 pollutants in 2015 in many developing countries. Climate response to non-CO 2 vehicle emissions.

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

Comparison of the potential reduction in emissions with the application of lower sulfur 0.5% MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances. Annex VI defines two sets of emission and fuel quality requirements: global requirements; and.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

Thus, the researchers concluded, switching from PFI to GDI vehicles will likely lead to a reduction in net global warming. We estimate ozone and SOA formation potential. Therefore, the secondary organic aerosol and ozone formation potential of the exhaust does not depend on engine technology. —Saliba et al.

80.27, “high ozone season” means the period from June 1 to September 15 of any calendar year and “regulatory control period” means the period from May 1 to September 15 of any calendar year. The result is more efficient combustion, cooler running engines, lower exhaust temperatures, and increased longevity of engine life. 40 CFR § 80.27

They accounted for both CO 2 emissions and emissions of ozone precursors (NO x , VOC, CO) and aerosols (BC or black carbon, OC, SO 2 ) as well as cloud effects (aviation-induced cirrus clouds and contrails)—i.e., In their study, Borken-Kleefeld et al. shorter-lived climate forcers (SLCFs).
