Project description
Cutting contrails to combat climate change
Contrails and other non-CO2 effects significantly contribute to global warming from air traffic. Mitigating these effects could halve aviation’s effective radiative forcing within a decade. However, large uncertainties currently hinder progress, even as the EU mandates contrail monitoring by 2028. The EU-funded A4Climate project will tackle this challenge by enhancing understanding of engine emissions, contrails, and their climate impact. The project will use a cutting-edge contrail prediction tool to evaluate 400 airline flights avoiding contrails. Groundbreaking research will investigate contrail formation by modern cleaner propulsion systems. A4CLIMATE will also generate critical and comprehensive atmospheric data from a unique research aircraft campaign. Bringing together partners across nine countries, A4CLIMATE aims to deliver actionable solutions, paving the way for sustainable aviation practices.
Objective
The mitigation of aviation non-CO2 effects, in particular contrails, could cut the radiative forcing from aviation by half in the next decade. Furthermore, the European Commission requires the Monitoring, Reporting and Verification of non-CO2 forcing agents by 2027. However, large uncertainties currently prevent the implementation of dedicated mitigation measures.
A4Climate directly targets the complex challenge of reducing aviation non-CO2 effects by advancing knowledge on engine particle emissions, contrails and their climate impact. Specifically, A4Climate improves weather and contrail predictions and integrates new information on contrail predictability, accuracy, climate impact and cost in a real time software. The contrail prediction tool will be validated on 400 contrail avoidance flights, thereby leveraging the consortiums expertise in the air transport system, weather and climate research. A4Climate creates further knowledge on contrail formation in the low-soot regime through dedicated lab measurements and models, filling gaps towards the assessment of the climate impact of modern lean burn and future hydrogen-based propulsion systems. Ultimately, A4Climate provides unique new atmospheric data on humidity, aerosols and contrails from an exceptional campaign with a research aircraft to improve process and climate models and to investigate fuel sulfur effects on contrails and low clouds.
Engaging policy and stakeholders early in the process, A4Climate will accelerate the evidence-based implementation of measures to reduce aviation non-CO2 effects. The 17 partners across academia, authorities and industry from 9 countries will collaborate over 4 years to ensure the success of the project with an overall budget of 8.1M including 4.8M EC contribution.
