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

Green Car Congress

SEPTEMBER 6, 2020

Eleven years have passed since the last time a similar study was conducted, and there has been a strong growth in the aviation sector since then, particularly in Asia. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions. —Marianne Tronstad Lund, co-author.

Following this BAU scenario, the researchers projected that air quality for the global average citizen in 2050 would be almost comparable to that for the average citizen in East Asia in the year 2005—an outcome which underscores the need to pursue emission reductions, according to the authors. —Pozzer et al.

These connections arise because in many cases the agents of concern are the same, and in many cases the sources of the agents are the same or intimately connected.For example, surface ozone is both an air pollutant and a greenhouse gas. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.

Ocean acidification caused by the absorption of carbon dioxide in seawater is already increasing along the California coast decades earlier than existing models predict. The growth in carbon dioxide emissions from energy and industry has exceeded even the most fossil-fuel intensive scenario developed by the IPCC at the end of the 1990s.

The researchers analyzed extensive satellite and ground-based measurements of nitrogen oxides and carbon monoxide. They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency.

NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health. NO 2 is a pollutant formed mainly from fossil fuel combustion, and traffic emissions can contribute up to 80% of ambient NO 2 in cities.

Climate benefits in the near-term (estimated using a GWP-20) are more than three times as large given the rapid benefits that the control of black carbon provides. Next-generation standards would target new reductions in emissions of NO x and non-methane hydrocarbons (HC), which are precursors to ozone and secondary particulate matter.
