Matthias Rüetschi presents the work he and his team lead at Services Industriels de Genève (SIG) in engaging with the current Swiss energy transition strategy. Matthias offers an overview of local programmes that aim to optimize energy efficiency while reducing CO2 emissions in Geneva, a city that as of 2017 runs entirely on renewable energy. Nora Kronig Romero, Counsellor, and Head of the Office of Specialized Institutions, at the Permanent Mission of Switzerland to the UN in Geneva, closes the seminar reflecting on the Swiss popular vote that will allow citizens to choose the source of the country’s energy.
