Experts Propose Low-Cost Solution to Reduce Jet Contrail Warming

Aviation experts suggest minor flight path adjustments could significantly cut contrail-induced climate impact for a minimal cost.

Contrails, the ice crystal clouds formed by jet exhaust, have a warming effect comparable to aviation carbon emissions.
Research indicates that 80% of contrail-related warming is caused by just 3% of flights.
Adjusting flight paths to avoid contrail formation could cut warming by over half by 2040, costing under £4 per flight.
The proposed changes focus on flights over North America, Europe, and the North Atlantic, particularly those at night and in winter.
The solution will be discussed at COP29, highlighting its potential as a quick, cost-effective climate action for the aviation industry.
