The advent of Aviation as means of transport revolutionized transportations over longer distance in terms of them being more economic and a safer mean.

But as nothing can have only advantages, the aviation industry too has its cons. The impacts of aviation especially on the environment are caused due to heat, noise, particulate matter and gases emitted by the aircraft engines. This in turn greatly contributes to climate change.

The recent rapid growth of the aviation industry has contributed an increase in air and noise pollution. Internal combustions processes taking place in the (ICE) internal combustion engine release large amounts of CO2 into the atmosphere, polluting it. 

Based on statistics from United Nations Intergovernmental Panel on Climate Change (IPCC), Aviation accounts for around 2% of the world?s man-made emissions of Carbon Dioxide. Globally, about 8.3 million people fly daily burning about 16.2 billion gallons of fuel annually.

Apart from CO2, the exhaust from aircraft engines is made up of: 7% to 8% CO2 and water vapour around 0.03% nitrogen oxides, unburned hydrocarbons, carbon monoxide and sulphur oxides traces of hydroxyl family and nitrogen compounds and small amounts of soot particles.

The water vapour contrails (the long trailing lines) are also thought to contribute towards Global Warming.

Despite all this the aviation industry is indeed doing its part in combating climate change with IPCC estimating that CO2 emissions would increase only two more percent by 2050,i.e., 5% of of human emissions.
