**New Solutions Proposed to Combat Climate Impact of Jet Contrails**
Experts suggest affordable measures to tackle the climate effects of jet contrails as COP29 highlights the issue.
The aviation sector could take crucial steps to mitigate the climate-changing effects of jet contrails, according to a recent study by aviation experts. Highlighted during the upcoming UN climate conference, COP29, in Baku, discussions aim to underline how just a few adjustments could lead to substantial environmental benefits at a minimal cost.
Jet condensation trails, commonly known as contrails, are often subject to unfounded conspiracy theories. However, scientists assert that the real issue lies in their contribution to global warming, with contrails, which form when hot aviation exhaust meets cold, humid air, effectively doubling the warming impact of aviation’s fossil fuel emissions.
Carlos Lopez de la Osa, a representative from the Transport & Environment campaign group, noted that these trails create artificial cloud layers, trapping heat that would otherwise escape into space. “The warming associated with contrails is comparable to the warming caused by aviation carbon emissions,” he stated, emphasizing the importance of addressing this overlooked source of climate damage.
Despite the myths surrounding contrails, which have led to sensational claims about “chemtrails,” experts insist that these theories lack scientific validation. Matteo Mirolo, involved in COP29 discussions, lamented how such misconceptions hinder progress and called for clearer consensus on the true environmental impacts of aviation.
The report outlines that just 3% of flights contribute to roughly 80% of contrail-related warming. By adjusting the flight paths of these select flights, the study estimates that it’s possible to cut contrail warming by over 50% by 2040, with changes costing less than £4 per flight. This could serve as a straightforward yet effective climate solution amid ongoing discussions about sustainable aviation fuels.
Factors like geography and flight timing also play crucial roles in contrail effects; for instance, flights traversing North America and Europe accounted for more than half of global contrail warming in 2019. Contrails formed during evening and night flights have been identified as having the most significant warming potential, with winter conditions exacerbating their effects.
“Current practices already include avoiding turbulence and thunderstorms. Now we must add minimizing contrail formation to our flight planning considerations,” Lopez de la Osa recommended. By addressing the contrail predicament at COP29, organizers hope to enhance public awareness and support the implementation of these actionable strategies. The potential for substantial climate improvements at a fraction of the cost presents a compelling case for immediate action in the aviation industry.
