As climate impacts intensify, adaptation can no longer be addressed in isolation from spatial planning, infrastructure, and decarbonization. Local authorities define territorial priorities and protect populations, while businesses, operators, and financial players possess the investment, innovation, and risk management capabilities essential for implementation. This 90-minute session will bring together local authorities and businesses for two complementary panel discussions. The first will focus on public-private collaboration regarding adaptation and water management, including water reuse and circular usage. The second will examine an integrated approach to mitigation and adaptation in the building and housing sectors. The discussion will aim to identify the conditions needed to shift from isolated projects to coherent territorial strategies and long-term collaborations, covering aspects such as shared responsibilities, governance at the appropriate scale, business models, financing, risk data, and the protection of vulnerable populations. This session is hosted by CN France in partnership with Entreprises pour l’Environnement (EpE) / Think Smartgrids / Institut de la Finance Durable (IFD) – Paris EUROPLACE.
