Major Climate Benefits with Electric Aircraft

Researchers at Chalmers University of Technology in Sweden have conducted the world's first life cycle assessment (LCA) comparing an existing two-seater all-electric aircraft, the "Pipistrel Alpha Electro," with its equivalent fossil fuel-powered counterpart. The study reveals that, after just one quarter of the expected lifespan of the electric aircraft, its climate impact is lower than that of the fossil fuel-based aircraft, provided it utilizes green electricity. The downside is an increase in mineral resource scarcity, particularly due to the use of rare metals in the batteries. The research highlights the potential of battery-powered electric aircraft to significantly reduce environmental impacts, achieving up to a 60% lower climate impact compared to equivalent fossil-fueled aircraft, with a trade-off of about 50% more mineral resource scarcity, mainly due to rare metals in the batteries.
The study compared the entire life cycle of both aircraft, considering various impact categories, such as global warming, mineral resource scarcity, particulate matter formation, acidification, and ground-level ozone formation. The researchers emphasized that, like electric cars, the initial climate impact of an electric aircraft is comparatively worse when brand new, as battery production consumes substantial energy and resources. However, over time and with usage, the relative impact decreases, reaching a break-even point after approximately 1,000 flight hours. Beyond this point, the electric aircraft becomes better for the environment, demonstrating a lower climate impact. The estimated lifespan of the aircraft is at least 4,000 hours, four times longer than the break-even time, under optimal conditions using green energy. The study also emphasizes the need for ongoing battery development to further reduce environmental impacts and improve the competitiveness of electric aircraft compared to their fossil-fuel counterparts.
