Lisbon has already cut emissions by over 40%, but reaching climate neutrality by 2030 requires stronger institutional and financial tools. The Lx Climate Lab provides this through three pillars: the citizen-facing Lisboa Clara Energy One-Stop-Shop, a Climate Action Fund, and a Climate Innovation Academy focused on renovation, energy poverty, and climate governance. In Year 1, Lisboa Clara became operational with dedicated staff and a hotline, the Climate Action Fund was fully designed, and the Academy shifted toward practical community engagement and energy poverty mapping. The project was presented to the Lisbon Municipal Council, and Lisboa E-Nova integrated the One-Stop-Shop with ADENE’s national energy platform, avoiding duplication and enabling wider scale.
