We recognize the urgent call to action from over 50 climate and aviation scientists, who have signed an open letter urging decisive steps to address aviation's non-CO2 emissions impacts during the final days of COP29 in Azerbaijan.
The climate emergency is undeniable. Certain sectors of the economy are significant drivers of this crisis, with transportation playing a key role—and aviation being one of its largest contributors. Between 2005 and 2019, global aviation traffic doubled, leading to a 40% increase in CO2 emissions. However, the climate impact of aviation extends far beyond CO2, and this is where a critical gap in action remains - creating an urgent need for immediate and focused action from all stakeholders in the aviation ecosystem.
We’ve known for sometime that non-CO2 effects—including nitrogen oxides (NOx), sulphur oxides (SOx), and contrails—warm the planet at least as much as aviation’s CO2 emissions. Due to the error bars on individual effects, often the industry has called for more research. But here leading scientists make their view clear.
At ZeroAvia, we are committed to eliminating aviation’s climate impact through scalable hydrogen-electric propulsion technologies. Hydrogen, when used in fuel cells addresses not only CO2 emissions but also NOx and PM. The only remaining emission is water vapor, and even that is at significantly lower temperature than with jet engines, presenting the opportunity to deploy management of this exhaust.
