GreAT is one of four running projects investigating different strategies to counteract aviation’s impact on climate change (granted from H2020 Call LC-MG-1-6-2019 « Aviation operations impact on climate change »). The three sister projects ClimOP (GA No 875503), ACACIA (GA No 875036) and ALTERNATE (GA No 875538) started at the same time. All four projects, administrated by INEA agency, aim for an intense research exchange and joint dissemination activities throughout their whole duration.
INEA project contributions to "low environmental impact" priority
Climate assessment of innovative mitigation strategies towards operational improvements in aviation (ClimOP)
- Determine innovative operational improvements (OI) to reduce impact on climate (electric taxiing, flexible runway usage, intelligent runway lights, optimised and flexible TMA operations, intermediate stops, formation flights etc.)
- Quantify climate impact of OIs
- Evaluate impact of the alternative sets of OIs for different stakeholders
- Develop harmonised mitigation strategies for each set of OIs
- Provide recommendations for target stakeholders on policy actions and supporting measures to implement the proposed OIs
Advancing the science for aviation and climate (ACACIA)
- To improve scientific understanding of those impacts that have the largest uncertainty, in particular, the indirect effect of aviation soot and aerosol on clouds.
- Identify needs for international measurement campaigns to constrain numerical models and theories with data and to formulate design options for such campaigns.
- To put all aviation effects on a common scale that will allow providing an updated climate impact assessment.
- To provide the knowledge basis and strategic guidance for future implementation of mitigation options, giving robust recommendations for no-regret strategies for achieving reduced climate impact of aviation.
Assessment on alternative aviation fuels development (ALTERNATE)
- Enlarge the aviation sustainable fuel framework, in both technical and economic areas, starting with the possible use of more feedstocks and sustainable production pathways than the existing ones.
- Evaluate new fuel candidates according to improved modelling methods, considering Life Cycle Assessment (LCA) optimization, climate change effects and technical, economic and environmentalconsequences of their use.
- Propose and test new advanced certification procedures to simplify and make more accurate the alternative fuel certification process.
- Evaluation of some possible ways to introduce a relevant amount of sustainable fuels in the air transport market, aiming to formulate specific recommendations for stakeholders on optimising the flight planning system and the use of those sustainable fuels
