Some halocarbons such as chlorofluorocarbons (CFCs), previously used as refrigerants, as propellants in spray cans and as solvents, are decreasing slowly as a result of the phase-out of these compounds through the Montreal Protocol on Substances that Deplete the Ozone Layer.

The 21CTP was formed in 2001 to reduce fuel usage and emissions in trucks of Classes 3 through 8. California’s and, potentially, EPA’s move toward further heavy-duty NO x reductions to meet National Ambient Air Quality Standards for ozone will be critical. These new targets need to be set for the research efforts.

Specifically, they proposed a method to assess the contribution of EVs to urban air quality in Belgium, compared to conventional vehicles of the same weight class; they modeled the effect on human toxicity (HT), photochemical ozone formation (POF) and particulate matter formation (PMF).

Resources then move from the weaker to stronger entities, and average productivity increases. For example, when China entered world markets as a major exporter of industrial products, production from less productive firms in Mexico was reduced or ceased altogether, thus diverting resources to more productive uses.

The study, by a team of researchers from Carnegie Mellon University, University of Georgia, Aerodyne Research, California Air Resources Board (ARB), Ohio State University, UC Berkeley, and UC San Diego is published in the ACS journal Environmental Science & Technology. We estimate ozone and SOA formation potential. —Saliba et al.

However, there are some serious questions over adverse effects, particularly depletion of stratospheric ozone. Evaluations of the geoengineering methods should take account of the major differences between the main two classes of methods—CDR and SRM.

In addition, it creates a program to provide financial incentives to retailers who sell high volumes of “Best-in-Class” appliances. The draft establishes a new energy efficiency resource standard to enlist electricity and natural gas distribution companies in the effort to make the nation more energy efficient.

R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. R1234yf (GWP = 4) ( earlier post ) is also a class A2 refrigerant. It is classified as an A2 refrigerant: minimal toxicity and moderate flammability. —Minjares, ICCT Working paper.

The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone. The California Air Resources Board and the US Environmental Protection Agency helped support this research. —Gentner et al. Gasoline or diesel?
