Aviation and climate change: Where to from here?

Written by Aviation Advocacy on . Posted in Climate change

In this, our second article on the role of aviation in climate change, we look at the expected growth in aviation emissions and how the industry plans to limit the impact of these increases. While the estimates of GHG emissions from aviation discussed in our previous article are being widely used in current discussion on climate change, many of these estimates are already 10-15 years out of date. Given that the aviation industry is regarded as one of the fastest-growing polluters, its share of global emissions is now likely even higher. Consider also that since 2000 global GHG emissions have increased by an average of 2.5% per year. Even if aviation’s share has remained constant, the actual volume will have increased. It is also worth noting that all the figures discussed so far are global totals, and that aircraft emissions contribute significantly more to climate change in the more mature aviation markets. In the US, currently the largest aviation market and also one of the world’s highest polluters, aviation accounts for 2.2% of GHG emissions while in Europe the figure is higher at around 3% – more than twice the global rate – and the UK is estimated to derive 6% of its total GHG emissions from aviation. This is particularly relevant given demand for air travel is expected to increase significantly over the next 20 years as new markets mature.
