WP5 – Synthesis, Impact and Outreach

Work Packages

WP5 ensures that A4Climate’s science reaches its full potential by translating complex results into usable tools, open-source software, and clear policy recommendations. It will foster informed decision-making by regulators, airlines, and manufacturers, accelerating the real-world adoption of contrail mitigation measures.

Goal: Turn the project’s research into practical tools, climate policy advice, and easy-to-understand information for decision-makers and the public.

How:

  • Develop a user-friendly software tool that shows contrail impact, costs, and uncertainties.
  • Simulate how cleaner engines, fuels, and contrail avoidance affect the climate.
  • Host workshops for policymakers and industry.
  • Communicate findings through websites, social media, reports, and open data.

Why: To make sure the science gets used — by airlines, manufacturers, and governments — and leads to real-world climate benefits.

Synthesis, Impact and Outreach

Key Technical activities:

  1. Development of Visualization and Decision-Support Software (Task 5.1)
    Develop open-access tools for visualizing contrail predictability, uncertainty, climate impact, and operational cost. The software will interface with models such as CoCiP/Pycontrails and be tailored to stakeholder needs.
  2. Climate Impact Simulations of Mitigation Measures (Task 5.2)
    Lead simulations of global contrail radiative forcing under scenarios with:
  • Modern lean-burn engines
  • SAF blending up to 60%
  • Contrail avoidance routing
    The updated CoCiP model including vPM activation will quantify mitigation benefits.
  • Mapping of Operational and Climate Costs (Task 5.3)
    Assess the operational impacts (e.g. fuel burn, maintenance, capacity) and monetize these against climate benefits of mitigation measures using outputs from WP3 and WP4.
  • Formulation of Policy Recommendations (Task 5.4)
    Based on scientific findings, the project will provide actionable policy guidance related to SAF implementation, cleaner engine design, and contrail avoidance strategies, aligned with Monitoring, Reporting and Verification (MRV) system for aviation non-CO₂ effects and the ReFuelEU Aviation     initiatives.
  • Dissemination, Communication, and Stakeholder Engagement (Task 5.5)
    Leads outreach efforts, including:
    • Project website and social media
    • Four stakeholder/EC workshops
    • Final public dissemination event
    • Open access publications and visual summaries
      These activities aim to ensure broad societal, political, and industrial uptake of the project’s results.
