In the 1951 film “Royal Wedding”, the inimitable Fred Astaire waltzes with none other than a hat rack, delivering a performance so effortlessly smooth it’s as if the object itself has rhythm. Astaire’s body, attuned to each shift and sway of the rack, moves with such elegance and anticipation that it becomes a partner in its own right. In a marvel of timing, he sidesteps, spins, and pirouettes around the object, both dancer and prop united in a masterpiece of choreography.
Could it be time for air travel, with its straight-arrow routes, to pick up a few of Fred’s slick moves?
New research from Transport & Environment (T&E) suggests that with a few deft adjustments to sidestep certain atmospheric conditions, aviation could significantly reduce the climate impact of contrails, those familiar white streaks trailing planes, which contribute as much to global warming as the CO₂ emissions produced by the entire aviation industry. Flights across North America, Europe, and the North Atlantic are responsible for the bulk of contrail-related warming, with flights in the evening, at night, and during winter adding significantly to the effect.
By subtly tweaking flight paths, we could halve contrail warming by 2040. Remarkably, this wouldn’t require a dramatic overhaul: a small adjustment for just a fraction of flights would suffice. According to T&E, rerouting to avoid contrails would add a mere $4 per flight. Even more striking is that just 3% of flights contribute to 80% of contrail-induced warming. Slightly redirecting these few flights would yield huge climate benefits, with minimal impact on fuel consumption.1
Overall, the study finds that the climate benefits of avoiding contrails would outweigh the extra CO₂ emissions by 15 to 40 times. Moreover, as new technology improves, these benefits are expected to increase.
For aviation, this climate-conscious manoeuvre serves not only the environment but makes economic sense for carriers. We may finally witness an age where progress and preservation are in step, gliding across the skies as harmoniously as a couple on a moonlit dance floor.
