The presentation is proposed under the back to school scheme of the European Commission which encourages EC staff to go back to the schools or Universities which educated them to talk about European policies. The talk will present the purpose of EU research and innovation policy, its policy instrument Horizon Europe through a focus on climate and biodiversity science including the social sciences and humanities dimension of those areas. A general introduction to opportunities for research as well as the role and impact of EU-funded research outputs in the design and implementation of the European Green Deal will be presented.
