Google is helping pilots route flights to create fewer contrails, which is better for the climate

Google, in collaboration with American Airlines and Bill Gates’ Breakthrough Energy, is developing sustainable flight routes to reduce the environmental impact of contrails, which account for about 35% of aviation’s global warming impact. Using AI and satellite imagery, they have developed a method to predict where contrails are likely to form, enabling pilots to avoid these areas and minimize the environmental footprint of aviation.

In a six-month trial involving 70 test flights, American Airlines pilots used Google and Breakthrough’s contrail forecast maps to reduce contrail formation by 54%. Although this resulted in a 2% increase in fuel consumption, the overall impact was a minor 0.3% increase across the airline’s entire fleet. The cost of this climate benefit, equivalent to avoiding a ton of carbon dioxide emissions, is estimated to be between $5 and $25. The research is yet to be peer-reviewed and further research is needed to determine the feasibility of large-scale implementation.

Key takeaways

Google, American Airlines, and Bill Gates’ Breakthrough Energy are working together to develop sustainable flight routes that limit contrails, which contribute to global warming.
Using AI and satellite imagery, they have developed a method to forecast where contrails are likely to form, allowing pilots to adjust their routes and minimize the environmental impact.
Test flights using this method reduced contrails by 54%, indicating that adjusting flight paths could be a viable way for the aviation industry to address climate change.
Despite the research showing promising results, it has yet to be peer-reviewed and more research is needed to determine if this method can be implemented on a larger scale.
