News & sources

This page is our workspace for everything that helps move the debate on contrail mitigation forward: new research, policy developments, field trials, media coverage, and the sources our work is based on.

Our work is grounded in science. Contrail mitigation is a serious field of research — and that means fake news, conspiracy narratives and unsupported claims have no place here. If we want to convince airlines, policymakers and the public, we need clear facts, reliable sources and language that remains accessible without becoming imprecise.

Credibility is essential. Not because it makes communication dry, but because this issue will only move into practice if research, regulation, industry and the public can work from a shared factual basis.

News

Here we collect current developments in the field of contrail mitigation — including research, trials and policy steps aimed at avoiding the most climate-damaging contrails.

Entries will be added regularly and briefly contextualised: What is new? Why does it matter? And what could it mean for real-world implementation?

History

This is where our source archive is being built: a structured and filterable collection of the studies, reports, organisations, projects and media pieces that inform our work.

The goal is not simply to collect as many links as possible. The goal is to make our basis transparent: Which scientific papers are central? Which organisations are driving the topic forward? Where are practical trials taking place? Which policy processes matter? And where are myths or false claims being addressed clearly?

Video

Our video series explains why contrails are more than just a visible side effect of flying — and why avoiding the most harmful ones is one of the most concrete climate opportunities in aviation.

The three parts guide viewers through the issue step by step: from the problem, to the solution, to the question of why voluntary action alone will not be enough.

Part 1: The problem

The first part explains why persistent contrails affect the climate, why they have long been underestimated in public debate, and why aviation’s non-CO₂ effects need to be taken seriously alongside CO₂.

Part 2: The solution

The second part shows that mitigation is possible: when flight planning, weather data and models work together, the most climate-damaging contrails can often be avoided through comparatively small adjustments.

Part 3: Why voluntary action is not enough

The third part explains why technical feasibility alone is not enough. For contrail mitigation to become part of everyday aviation, we need clear rules, reliable data, political responsibility and public pressure.
