🗞️ Driving the news: New EU climate regulations will require airlines operating from European airports to report the estimated climate impact of vapour trails, or contrails, in addition to carbon dioxide emissions
The rules, agreed upon on August 30th, aim to enhance understanding of aviation’s non-CO2 environmental impacts despite opposition from the airline industry
Initially, these requirements will only apply to flights within the European Economic Area, expanding to all flights into and out of the EU by 2027

🔭 The context: Contrails are known to contribute to global warming by promoting cloud cover that traps heat in the atmosphere
Although the exact impact of contrails is uncertain, the European Commission stresses that this uncertainty should not prevent action
Environmental advocates criticize a temporary exemption for long-haul flights, arguing it weakens efforts to address the full climate impact of aviation.

🌍 Why it matters for the planet: Monitoring and reporting the impact of contrails represents a crucial step in addressing aviation's broader role in global warming
As the aviation industry accounts for approximately 2% of global CO2 emissions, regulating non-CO2 emissions like contrails can significantly contribute to climate mitigation efforts

⏭️ What's next: From next year, airlines will start reporting contrail impacts for flights within the European Economic Area
By 2027, this reporting will extend to all flights entering and leaving the EU, alongside a focus on sustainable aviation fuels that meet stringent carbon footprint criteria

💬 One quote: “Studies have shown that the uncertainty in these effects is not a sufficient reason to avoid action,” stated the European Commission, underscoring the importance of addressing non-CO2 emissions

📈 One stat: Contrails' contribution to global warming could be at least as significant as the 2% of global CO2 emissions produced by aircraft.
