As a member of the Advisory Board for Sustainable Development at the University of Tübingen and of Scientists for Futures, Jörg Tremmel is committed to ensuring that Germany makes its contribution to achieving the 1.5 to 2 degree Celsius target of the UNFCCC Paris Agreement. As part of a voluntary commitment, he has decided not to take short-haul business (and private) flights of up to 1,000 km, provided the distance can be covered in less than 12 hours by train.
