Climate change[ edit ] Radiative forcings from aviation emissions gases and aerosols in as estimated by the IPCC Like all human activities involving combustionmost forms of aviation release carbon dioxide CO2 and other greenhouse gases into the Earth's atmospherecontributing to the acceleration of global warming [12] and in the case of CO2 ocean acidification.

Carbon dioxide CO2 [ edit ] CO2 emissions from aircraft-in-flight are the most significant and best understood [20] element of aviation's total contribution to climate change. The level and effects of CO2 emissions are currently believed to be broadly the same regardless of altitude i.

Inemissions of CO2 from aircraft were estimated at around 2 percent of all such anthropogenic emissions, and that year the atmospheric concentration of CO2 attributable to aviation was around 1 percent of the total anthropogenic increase since the industrial revolution, having accumulated primarily over just the last 50 years.

The effect of O3 surface concentrations are regional and local, but it becomes well mixed globally at mid and upper tropospheric levels. But this effect does not offset the O3 forming effect of NOx emissions. It is now believed that aircraft sulfur and water emissions in the stratosphere tend to deplete O3, partially offsetting the NOx-induced O3 increases.

These effects have not been quantified. Water vapor H2Oand contrails[ edit ] Cirrus cloud formation One of the products of burning hydrocarbons with oxygen is water vapour, a greenhouse gas. Water vapour produced by aircraft engines at high altitude, under certain atmospheric conditions, condenses into droplets to form condensation trailsor contrails.

Contrails are visible line clouds that form in cold, humid atmospheres and are thought to have a global warming effect though one less significant than either CO2 emissions or NOx induced effects.

Cirrus clouds have been observed to develop after the persistent formation of contrails and have been found to have a global warming effect over-and-above that of contrail formation alone.

There is a degree of scientific uncertainty about the contribution of contrail and cirrus cloud formation to global warming and attempts to estimate aviation's overall climate change contribution do not tend to include its effects on cirrus cloud enhancement.

The former are decreased and the latter are increased, in comparison to temperatures the day before and the day after such outbreaks. Soot absorbs heat and has a warming effect; sulfate particles reflect radiation and have a small cooling effect.

In addition, particles can influence the formation and properties of clouds, [26] including both line-shaped contrails and naturally-occurring cirrus clouds.

The impact of "spreading contrails and cirrus clouds that evolve from them -- collectively known as contrail cirrus -- have a greater radiative forcing RF today than all aviation CO2 emissions since the first powered airplane flight".

2018 Pilot Outlook

All aircraft powered by combustion will release some amount of soot; although, recent studies suggest that reducing the aromatic content of jet fuel decreases the amount of soot produced.

Also, the effect of a given amount of emissions on climate radiative forcing is greater at higher altitudes: About 60 percent of aviation emissions arise from international flights, and these flights are not covered by the Kyoto Protocol and its emissions reduction targets. This was not accounted for in prior standard carbon accounting methods.

The study concluded that when considering respective average load factors percent of occupied seats in each of the seating classes, the carbon footprints of business class and first class are three-times and nine-times higher than economy class.

But that spin is based on a maximum-capacity aircraft configuration, or about economy passengers. In reality, a typical A aircraft has seats.

Its fuel performance is comparable to that of a B ER and even about 15 percent worse than a BER on a passenger-mile basis calculated using Piano-5 on a flight from AUH to LHR, assuming an 80 percent passenger load factor, and in-service fleet average seat counts. Total climate effects[ edit ] In attempting to aggregate and quantify the total climate impact of aircraft emissions the Intergovernmental Panel on Climate Change IPCC has estimated that aviation's total climate impact is some 2—4 times that of its direct CO2 emissions alone excluding the potential impact of cirrus cloud enhancement.

While there is uncertainty about the exact level of impact of NOx and water vapour, governments have accepted the broad scientific view that they do have an effect.
