The overall objective of SECAP (Interreg Italy-Slovenia) is to foster the sustainable development of a cross-border context by promoting low-carbon strategies for all types of territories, in particular urban areas, by creating relevant adaptation and mitigation measures (Axis 2 Priority 4e). The project areas are the Metropolitan City of Venice (CMVE), the Autonomous Region of Friuli-Venezia Giulia (RAFVG) and the Western Region of Slovenia. The project will lead to cross-border sharing of tools, methodologies and databases and will generate positive impacts on local planning throughout the area by promoting the sustainable development models of the Covenant of Mayors with improved quality of life and resilience to climate change. The common challenge of the project is to offer practical support to municipalities in the partner area for the implementation of sustainable energy and climate adaptation policies, which are reflected in the transaction from SEAPs to SECAP. The main objective of the project is to improve energy planning by local operators, focusing on energy saving, renewable energies, reduction of CO2 emissions and mitigation measures related to climate change. The change, which is to be implemented, derives from the choice of a strategic transnational approach, which will lead to the development of timely adaptation measures, ensuring coherence between different sectors and levels of governance, in order to understand the impacts of climate change and to implement policies for optimal adaptation, through the development of regional and local strategies, consistent with national ones. The presence of Slovenian Ministries, as associated partners, and the FVG Region guarantees the sharing of choices with governance bodies to ensure the coherence of the strategy with national and regional action plans and development policies. The results will be a unified cross-border strategy, which will ensure the transaction towards a green economy, proposing new job opportunities; training sessions for municipalities and public awareness; transition of some SEAPs into CFSP; other pilot actions aimed at defining methodologies for a CFSP adapted to local needs, as well as small infrastructure investments to monitor atmospheric emissions and energy consumption.
