Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Source: University of Leicester.

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

SEPTEMBER 6, 2020

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. Here, we present a new comprehensive and quantitative approach for evaluating aviation climate forcing terms. Pitari, M.J. Prather, R.

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.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

AUGUST 21, 2009

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

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).

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

OCTOBER 14, 2009

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships. 1 from shipping in 2007, corresponding to 3.3% 1 of the total ship emissions in 2007.

And hydroxyls drive long chains of reactions involving other common gases, including ozone. That’s noteworthy because nitrogen oxides have primarily been associated with ozone formation and warming in the past. These effects may be important but are highly uncertain at present.

In 2000, the ARB established California’s Diesel Risk Reduction Plan, which aims to reduce diesel emissions to 85% below 2000 levels by 2020. NO x helps create ground-level ozone, or smog.
