I am focusing on what are called the primary standards, which are health-based, and on two key pollutants, particulates and ozone, which have the greatest current importance. Ozone Pollution (Smog) Ozone standards are measured in parts per million (ppm) in the air. With that in mind, I’ve put together some brief timelines.

Carbon dioxide emissions are the leading cause of climate change, and nitrogen oxides contribute to the formation of ground-level ozone, which affects the health of children, older people, people with lung diseases such as asthma and emphysema, and people who work or are active outdoors.

EPA has been implementing the Good Neighbor Provision since the 1990s to successfully reduce significant contributions from power plants (and sometimes other types of big industrial sources) to ozone pollution (also called smog) in downwind States. EPA’s latest Rule finalizes federal plan requirements for 23 upwind States.

This compliance threshold is one of the most pivotal parts of the regulation and it should be based on well-researched and tested desired outcomes – e.g. if we want X amount of emission reductions, we should regulate fleets of Y size and greater.

Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone. They are water vapor, carbon dioxide, methane, nitrous oxide, ozone, CFCs, and hydrofluorocarbons.

The lines form a chemical fingerprint that could be used to find “biosignatures” such as oxygen or ozone. But to ensure their exoplanetary biosignature techniques work, they first want to test them out on the Earth, which is the only world we know of that does contain life. The Moon to the rescue.

EPA testing has shown that a vehicle’s emissions can increase drastically (tens or hundreds of times, depending on the pollutant) when its emissions controls are removed. This is made possible by careful engine calibrations, and the use of filters and catalysts in the exhaust system.
