The analytical briefs explore the energy sufficiency gap and potential for the buildings and transport sectors in light of the energy and climate context of each country. In the reports, experts from CACTUS national implementing partners LEI and REKK analyse the national legislative frameworks, socio-cultural barriers and enablers, as well as key indicators describing the energy demand. The briefs make first recommendations with a view to reaching more ambitious climate mitigation levels and for the next steps of the project.
