Controversy: The Clean Air Act

Decent Essays

The Clean Air Act has not experienced much revision since its conception in 1970. Recently, there have been attempts to include greenhouse gases, like carbon dioxide, in the legislation and execution of the Clean Air Act to make the list of criteria pollutants more comprehensive while simultaneously battling the emerging threat of climate change. This movement was initially sparked by the Montreal Protocol, which aims to eliminate the production and consumption of ozone depleting substances to limit damage to the ozone layer (International Actions, 2016). However, there has not been an official movement to include greenhouses gases into the Clean Air Act, because stakeholders have not been able to agree on a comprehensive market-based legislation …show more content…

The Heritage Foundation claims that controlling carbon dioxide would inflate federal expenditure and have negative economic impacts (Lieberman, 2008). Additionally, Lieberman (2008) claims that the EPA should not act on climate change issues before Congress takes a firm stance on either side of the issue. Controversy concerning this matter has prevented the EPA from moving forward and making any limits on carbon dioxide. The Clean Power Plan, which was introduced in 2008, was the first federal plan to reduce carbon dioxide emissions. However, this plan is currently being reviewed by the Trump administration and may be dismantled or drastically altered to halt the implementation of renewable energies. If the EPA were to mandate reductions in carbon dioxide and other greenhouse gas emissions, air quality would decrease because less particulates would be in the …show more content…

The European Union has developed approaches similar to those implemented in the United States. The European Union has set standards for particulate matter, ozone, sulfur dioxide, nitrogen oxides, lead, and other pollutants that are harmful to health and the environment (Air Legislation, 2016). This list of pollutants is essentially a more expanded list of criteria pollutants set forth by the EPA. However, the European Union has taken a step further and set a national ceiling for pollutants, which means that countries in the EU must keep their total emission levels of pollutants under a specified level (Air Legislation, 2016). Some pollutants, like sulphur dioxide and nitrogen dioxide, have permitted exceedances each year where the concentration can exceed the ceiling in place, but even the largest exceedances are below 10% of the calendar days (35 days/ year) (Air Quality Standards, 2016). This aggressive approach has successfully resulted in decreased air pollution in Europe. Since the European Union is comprised of many countries, it is the country’s discretion on how to manage the pollutants so that they remain below the legal limit, which is similar to the approach the United States has on managing criteria pollutants. Of course,
