The experiments conducted by Google and American Airlines demonstrate that utilizing artificial intelligence models can help airlines reduce contrail cirrus, with an anticipated reduction of up to 54%. This is a small yet significant victory that contributes to decreasing aviation emissions. The formation of contrails occurs when soot from jet fuel combustion in aircraft engines combines with water particles in moisture, forming ice. Collaborating with American Airlines, Google aims to identify flight routes that do not produce contrails and has developed a contrail prediction map. Avoiding contrails may cost between $5 to $25 per ton of CO2 equivalent, potentially making it competitive with other measures to reduce warming effects.
