Some of the substitutes for ozone-damaging chemicals that being phased out worldwide under international agreements are themselves potent greenhouse gases and contribute to warming. This work was supported in part by NOAA’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) Program and NASA’s Atmospheric Composition Program.

Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.

NO x emissions have not been decreasing as expected in recent years (2011–2015) when comparing top-down estimates from satellites and surface NO 2 measurements to the trends predicted from the US Environmental Protection Agency’s emission inventory data, according to a new study by an international team of researchers.

The cap is enforced by requiring each source that operates under the cap to turn in one allowance or offset credit for every metric ton of carbon dioxide equivalent (MTCO 2 e) that it emits. California has been working with strategic partners in the forest and cement sectors to explore sectoral crediting approaches to international action.

As with the earlier assessment, this study consists of two separate, but related, analyses: greenhouse gas emissions from 2015-2050, and air quality impacts in 2030. In the Lower GHG scenario, in 2050, total emissions for the electricity and transportation sectors could be reduced by 2610 million metric tons relative to 2015 levels.

While that report projected vessel activity, it did not explore the environmental impacts of increased shipping in terms of air emissions or the potential climate impacts from increases in short-lived climate pollutants such as black carbon. —Azzara and Rutherford, ICCT Working Paper 2015-1.

The cap-and-trade program also works in concert with other measures, such as standards for cleaner vehicles, low-carbon fuels, renewable electricity and energy efficiency, and complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants. Click to enlarge.
