To ensure the quality of the air we breathe air quality laws are touching on some important areas and they have appropriate means to stop all illegal emissions of pollutants. This time, I will write about four areas in which air quality laws have a significant influence, emission standards, technology requirements, bans and data collection.
Standards of the emission are requirements that every company that has by-product that may be regarded as pollutant must follow to preserve the quality of the air. These standards are in most cases made in the form of allowed emission in some time-frame. Everything above that is damaging to the people that live near that company. There is, not only one method for making those emission standards, but there are few. It depends on few factors, industry, source of the pollutants and air pollutant itself.
The control of the technology requirements is another task that is governed by air quality laws. The point is to develop technologies that would be approved by the government. When the government passes a particular technology that will reduce the emission of pollutants, and then it can adopt the law of air quality that will force all companies that have an emission of that pollutant to use that technology to reduce its emission. Not every technology that helps in reducing the emissions is used due to few factors. Those factors represent the economic cost of that technology, availability, feasibility as well as effectiveness.
If a pollutant is too hazardous at any level of emission, then air quality laws can become legislation that will ban that substance from use. Some laws limit pollution from some substances to zero, but that is not same as the prohibition of the substance. Freon is a case in point; a substance that was used in refrigerators was banned due its strong potential of ozone depletion.
Data collection is a crucial factor in the implementation of air quality laws. This collection is more than often done in several ways that are recognized by everyone. These techniques include constant monitoring of the ambient air for any presence of possible pollutants and direct supervision of the pollutants sources.
It is impossible to attain perfect air quality as it would mean the closure of many of the companies and don’t forget the transport which would be limited to vehicles that produce no pollutants. The governments are reluctant in the passing of the new laws that would reduce the allowed air pollution levels as they directly damage the economy, and that hurts the people who don’t want to lose the money.
The richest people in the world are found in the industry, and every law that limits the amount of pollution if the air hurts them and they are fighting against those laws (it is sad that they are successful). Massive sums of money are invested in the struggle against new legislation and due to that the laws that would make our air healthy, or even close to normal, never see the light of the day.
