CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modeling shows that the oceans take much less ozone out of the atmosphere than previously thought. Ozone (O 3 ) is formed by reactions of chemicals such as nitrogen oxides and volatile organic compounds—i.e.,

This action is based on the premise that federal law preempts state and local tailpipe greenhouse gas (GHG) emissions standards as well as zero emission vehicle (ZEV) mandates. The California waiver authority exists because California has uniquely difficult problems with ozone-forming pollutants. Earlier post.)

The Northwestern team, with colleagues from Boston University and the NOAA Geophysical Fluid Dynamics Laboratory in Princeton combined climate modeling with public health data to evaluate the impact of electric vehicles on US lives and the economy. Results show that in more aggressive scenarios—i.e.,

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. Per capita GHG emissions in California have dropped from a 2001 peak of 14.0 tons per person to 10.7 tons per person in 2018, a 24% decrease.

The California Air Resources Board’s latest state inventory of greenhouse gas emissions shows that California’s GHG emissions continue to decrease. These reductions have occurred while California’s economy has continued to grow. These reductions have occurred while California’s economy has continued to grow. Source: ARB.

Costs per gram per kilometer of CO 2 e reduced are attractive for all three alternatives relative to the cost of the engine technology package expected to be employed for fuel economy compliance in China. These older systems used chlorofluorocarbons (CFC-12) as the refrigerant gas.
