Aviation

Despite slackening growth in 2017-2018, demand is expected to remain strong in the future. Meanwhile, impressive efficiency improvements achieved since 2000 also show signs of slowing down.

Global aviation activity is continuing to grow rapidly

CO2 emissions from aviation continue to rise, and accounted for around 2.5% of global energy-related CO2 emissions in 2018. While energy efficiency in aviation improved by 3.2% per year between 2000 and 2014, it slowed to less than 1% per year between 2014 and 2016. In the Sustainable Development Scenario, aviation energy efficiency needs to improve by more than 3% per year to 2040. With global aviation activity continuing to grow rapidly (+140% since 2000), further international policy measures, such as more stringent carbon pricing and efficiency standards, could help put aviation on track.
