At the same time, research on ozone depletion showed the dire situation and helped support pushes for reform and regulation of harmful chemicals being used in such a vulnerable context as in our atmosphere. Many Western nations have passed legislation limiting the types of chemicals and levels which are acceptable, for example the Air Pollution Act in the United States (U.S. Environmental Protection Agency 2010). Conclusions

With this growing amount of data, it is clear that stricter regulation will be necessary to curb future ozone and water pollution as a result of the growth of the aviation industry. We cannot completely ban airline travel, and so resources need to be implemented in finding safer alternatives for the harmful chemicals necessary in massive airline travel.

Increased Production of Ozone in Presence of Aviation Emissions

IPCC Ozone Production (http://www.grida.no/publications/other/ipcc_sr/?src=/Climate/ipcc/aviation/014.htm)

This chart represents the increased production of ozone in three cases where Nitrogen Oxide, (NOx) is present. Case 0 shows the levels of naturally occurring NOx levels and the production rates of ozone which correlates with...

Case 1 presents the reflection of current airborne readings of increase NOx levels. This shows an increase in ozone production. Case 2 is the hypothetical representation of massively increased ozone production in the event of an increase of NOx continues to higher levels.
Appendix D

IPCC Ozone Loss Rates (http://www.grida.no/publications/other/ipcc_sr/?src=/Climate/ipcc/aviation/014.htm)

NOx increases the loss rate of ozone within the stratosphere. The left table shows the loss rate of the ozone in terms of percentage per month, based on the corresponding altitude levels. The right panel portrays 20 & more nitrogen is introduced into the stratosphere.

Appendix E

This chart shows the three major emissions outside CO2 and NOx, and how they create particles that will then freeze and form into cirrus cloud particles. The chart outlines the chemical processes after such compounds are emitted from jet engines.
