Airlines Face Major Hurdle in Addressing Climate Impact

A significant milestone was achieved when a Virgin Atlantic flight made history, becoming the first to cross the Atlantic using entirely sustainable aviation fuel. The journey from London to New York was more than a testament to fuel innovation; it signalled a broader commitment to tackling aviation's impact on climate change.

Contrails: The Overlooked Culprit in Climate Change

Sky-high research onboard the Boeing 787 Dreamliner extended beyond alternative fuels to scrutinize the environmental effects of condensation trails—known as "contrails." These clouds, formed by soot and water vapor emitted from jet engines, can sometimes linger, trapping heat and exacerbating global warming under specific atmospheric conditions.

While traditional jet fuel accounts for approximately 2.4 percent of annual carbon dioxide emissions globally, the overall climate impact of flying could rise to 4 percent when including contrails and other non-CO₂ emissions, according to a 2021 study.

Navigating the Skies for a Cooler Planet

Finding a solution to the contrail conundrum lies in the ability to predict their formation accurately. As researchers and tech companies develop precise forecasting tools, airlines could alter flight paths to dodge potential hotspots, reducing the warming effect of these icy sky streaks.

"Confidence in contrail forecasts" is crucial for airlines looking to mitigate this issue, explains Joey Cathcart from RMI, a clean energy think tank. This adds a strategic layer to flight planning—balancing operational efficiency with environmental responsibility.

Contributions to this cause were active aboard the Virgin Atlantic flight, with pilot observations being made about contrails left by preceding aircraft. Such in-flight data help in refining predictive models and complement existing satellite and ground-based observational methods. The aspiration is to accumulate a comprehensive set of data by expanding this practice across the industry.

Cathcart believes in the value and feasibility of pilot reporting, especially considering its minimal cost and ease of implementation—a sentiment shared in the aftermath of this groundbreaking transatlantic trip.
