![]() But the one that gets the most attention is its contribution via CO 2 emissions. The latter two numbers refer to 2018, and the first to 2016, the latest year for which such data are available.Īs we will see later in this article, there are a number of processes by which aviation contributes to climate change. 3.5% of ‘effective radiative forcing’ – a closer measure of its impact on warming.1.9% of greenhouse gas emissions (which includes all greenhouse gases, not only CO 2).Global aviation (including domestic and international passenger and freight) accounts for: How much of a role does aviation play in global emissions and climate change? In this article we take a look at the key numbers that are useful to know. This means they could be easily overlooked – especially since international aviation is not counted within any country’s emissions inventories or targets. It’s also important to note that unlike the most common greenhouse gases – carbon dioxide, methane or nitrous oxide – non-CO 2 forcings from aviation are not included in the Paris Agreement. The fact that they don’t count towards the emissions of any country means there are few incentives for countries to reduce them. International flights are not – instead they are counted as their own category: ‘bunker fuels’. CO 2 emissions from domestic flights are counted in a country’s emission accounts. The second is how aviation emissions are attributed to countries. This is because there are large inequalities in how much people fly – many do not, or cannot afford to, fly at all. Yet aviation overall accounts for only 2.5% of global carbon dioxide (CO 2) emissions. Air travel dominates a frequent traveller’s individual contribution to climate change. The first is the disconnect between its role in our personal and collective carbon emissions. Flying is a highly controversial topic in climate debates.
