taxi on with a significant lower fuel burn, leading to lower emissions.
Due to aircraft fleet renewal in the aviation industry with the introduction of more fuel-efficient engines, emissions of unburnt hydrocarbons, carbon oxide and particulate matter such as soot have been relatively stable between 2005 and 2014. Neo engines have been producing 15% less fuel burn than its predecessors. The A320 Neo is projected to provide an estimated 20% decrease in CO2 emissions and fuel burn by 2020, which is hoped to be achieved through further engine efficiency improvements and cabin innovations.
Biofuels are also an option as some of them are carbon neutral which means the carbons are created and taken away at the same rate. ICAO has recognised this problem and agreed on a global market-based measure for CO2 emissions from the aviation industry. The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) hopes to achieve their goal of stabilising CO2 emission levels by 2020. The resolution will require airlines to monitor emissions on all international routes and offset emissions from these routes by purchasing eligible emission units that reduce emissions e.g. renewable energy.
Is the aviation industry doing enough to prevent climate change?
There is no doubt but that the aviation industry is a large contributor to environmental pollution in several ways.
However, it is also clear that serious steps are being taken at international and national level to minimise the negative environmental impacts generated by the industry. The aviation sector will need to remain committed to advancing technology, operations and infrastructure to reduce the sector’s carbon emissions. The industry must continue to strive for improvement and equally must try to ensure compliance with all regulations and those found to be in breach must be punished if the industry is to have credibility. Whilst it is not possible to repair the environmental damage the industry has caused to date, it is undoubtedly the duty of the industry to create solutions to minimise the negative environmental effects of aircraft into the future.
There is also the optimistic way of seeing thing as one of the DCU student wrote:
Studies have shown that noise causes a decrease in the prices of houses, and a reduction in the price of land, and shows this as a negative economic impact of noise. However, I believe that this is opposite for Dublin. Dublin’s population grew by 74,000 people between 2011 and 2016, with a projected additional 245,000 people to occupy the city by 2040. In the current economy where house and land prices have sky-rocketed by almost 40%, since the recovery of the economy in 2013, affordable housing is required for an over-populated city. This is a benefit for the population of Dublin looking to get on the property ladder, with a quite regulated aviation market in terms of aircraft movement curfews.
