Restrictions on Air Quality: Theory and Empirical Evidence." (2015).

The authors of the article outline the impacts of restricting other means of transport, such as driving on the quality of the environment. This article will be a good source of information on the extent of air pollution reduction when various methods of travel other than flying are controlled. This can then be compared with the effect witnessed when air travel is restricted.

Area by Numerical Simulation.” Environmental Engineering & Management Journal (EEMJ), 10.1 (2011).

This research journal gives the results of a study on the quality of air in the areas around the airport. According to this research, air around the airport is highly polluted due to the high number of airplanes leaving the airport. It offers information on impacts of reducing the number of flights on the air around the airport region which can be a reflection of the whole world.

This article contains information on the origins of the various debates that have been going on as far as air pollution and air travel restrictions are concerned. The author describes the effects of air travel on air quality and gives the details of how restricting air travel can add to the international fight against environmental pollution.

Ashden Trust, London (2009).

Since the supporters of air travel have been engaged in a debate with those against it, the author of this particular article provides facts on the economic, social and environmental impacts of flying. From this article, the positive and negative effects of restricting air travel can be obtained. As such, this article adds to the existing debate on whether restricting air travel is the best method of reducing air pollution of not.

7. Policy Green Party. 3 2015. 25 2 2016 <https://policy.greenparty.org.uk/tr.html>.

The article gives facts on the current situation as far as statistics on air travel are concerned. It outlines some of the various methods of controlling air pollution that governments have employed before. However, the article notes that, despite the various measures applied (except air travel restriction), the amount of carbon emissions from air travel are on the increase.

pollution/>.

The website provides data on the extent of the effects of air travel on the environment. In addition, other various measure that have been used before to control air pollution from air travel are outlined. The author(s) also note the failure of the aviation industry to reach the level of carbon emission as agreed upon internationally.

pp.1233-1242, (2002)

The journal article describes the various sources of air pollution. Of interest is the level of air pollution resulting from air travel despite the various methods that have been input to reduce the amounts of CO2 and NO2 from flying.

2015. 25 2 2016 <http://www.ilocis.org/documents/chpt55e.htm>.

The article discusses the various ways of controlling air pollution. The author argues that, although air restriction can reduce air pollution, there are better methods of reducing air pollution at lesser costs.
