Independently from the Paris Agreement, all major airlines voluntarily committed to mitigate climate change. After 2027, the climate change program known as Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) will become mandatory.
According to Forbes, emission levels in 2020 are expected to triple by 2050. Nevertheless, a 2020 cap may prove insufficient when the goal is to limit climate change and global temperature rise below 2°C. The world needs to achieve net-zero emissions by 2050. Etihad Airways is targeting zero net carbon emissions by 2050 and Lufthansa will increase fuel efficiency by 1.5% in 2020.
Airlines now have the opportunity to adopt more fuel-efficient aircraft and use innovative technologies that help reduce greenhouse emissions from all sectors. In its plan to support the US commitment to climate mitigation, UAT is developing a new class of aircraft fastener that is designed to improve fuel efficiency by reducing the overall weight of an aircraft. If implemented with integrity, UAT could prevent up to 1,500 tons of carbon dioxide emissions per aircraft in one year. That is 200 times what U.S. households emit each year.
