We can drastically cut aviation's climate impact.
Contrails cause 1 – 2% of global warming. We can eliminate most of that at near-zero cost.
Contrails cause 1 – 2% of global warming. We can eliminate most of that at near-zero cost.
Aircraft cause warming in two ways: greenhouse gas emissions and contrails. That's because contrails (aircraft condensation trails) often grow into cirrus clouds that trap heat in the lower atmosphere and significantly add to global warming. Recent estimates show that contrail-cirrus warming is roughly equivalent to the warming caused by the greenhouse gas emissions of those same aircraft.

We are advancing the latest science and building contrail mitigation systems that can be used by the aviation industry to significantly reduce their climate impact, immediately. Still curious? Go deeper on the science.
Learn More »Reviate is a working group at Breakthrough Energy focused on contrails. We are a small team of engineers and scientists building on the work of our many collaborators to enable, verify, and ultimately accredit contrail-mitigating flight operations. The core of our work is open-source software tools that can accurately forecast and verify contrail impact and inform more sustainable flight plans. Learn more about our mission, team, and collaborators.

Start exploring »Aircraft condensation trails—or contrails—can turn into artificial cirrus clouds that trap radiation and significantly add to global warming. Recent estimates show that contrail-cirrus warming is comparable to the total CO2 emissions of aviation.
