The FORUM-AE coordination action will create a technical specialists european network with all relevant competencies, including academic and industrial partners, linked to key environmental technical issues on aviation emissions.It will address equitably three complementary aspects: environmental impacts (air quality and climate change), technical and technological mitigation solutions (aircraft, engine, operations, alternative fuels), regulation technical issues (CAEP issues, local regulations).In this scope, the activity will consist in the organization of focused and high quality workshops and in the monitoring of major european R&T programs, both activities being carried out closely.European experts outside the project consortium will be also invited to contribute to the workshops as well as focal points of other existing projects where useful assessments are made such as Clean-sky, Sesar... and these focal points will contribute in giving a status of their projects.The objectives will be: (a) to offer a European forum where fruitful exchanges will be possible between main air transport actors, (b) to achieve a better understanding on emissions linked environmental priorities, a better visibility on most promising solutions, and technicalrecommendations on regulation issues, (c) to give clear status on most relevant R&T european programs, and recommend future R&T directions. Results will be delivered and disseminated through the workshops, their proceedings, website and publications.
