Globally, aviation accounts for 4.9% of the CO2 and non-CO2 emissions. Industry is taking steps to reduce aircraft emissions and improve fuel efficiency in an effort to combat climate change but with twice as many air travelers expected by 2037, those efforts alone will not be enough. It’s clear that bringing the aviation industry in line with UNFCCC and other sustainability goals will require commercial aircraft to transition to alternative energy sources such as biofuels and electric power. And this transition implies the complete redesign of multiple aircraft subsystems, up to and potentially including the airframe itself. Bring your curiosity to this unique Ask Siemens Anything Q&A session in which Siemens aerospace experts will field questions on the future of sustainable aviation. From strategies for replicating a jet engine’s power density in green propulsion systems to analysis of clean energy sources and their implications on aircraft design, tune in and ask away as the leading climate-neutral aircraft technology supplier answers what will propel air travel into 2050 and beyond.
