The implementation of the project ‘‘The Road to Successful Decarbonization with Cassette Green Roofs’’ took place in June this year. This project is part of the project “EU for a Green Agenda in Serbia” and is implemented with the technical and financial support of the European Union and in partnership with the Ministry of Environmental Protection, implemented by UNDP in cooperation with the Embassy of Sweden and the European Investment Bank (EIB), with additional financial resources provided by the governments of Sweden, Switzerland and Serbia. It was a pleasure to spend the day with curious and hardworking young people.
