Upscaling local innovation: metropolitan retrofit governance in Barcelona through the ‘Pla Metropolità de Rehabilitació d’Habitatges 2020–2030’

This policy paper examines the development and implementation of the Pla Metropolità de Rehabilitació d’Habitatges (PMRH) in the Metropolitan Area of Barcelona, the first long-term metropolitan strategy for housing rehabilitation and energy upgrading in Spain. Originating from a successful municipal initiative that exceeded local borrowing capacity once offered European Investment Bank financing, the PMRH illustrates how metropolitan governance can develop pragmatically through the need to scale local innovation. The programme introduces a needs-based, redistributive approach that directs resources toward municipalities and neighbourhoods with structurally deficient housing stock, lower incomes, and higher energy vulnerability, while providing technical assistance to municipalities with limited administrative capacity. However, its implementation has been significantly shaped – and constrained – by the arrival of Next Generation EU funds, which imposed higher technical standards, compressed timelines, and administrative pressures that reduced the programme’s initial scope. The paper argues that metropolitan authorities can play a strategic intermediary role in Europe’s green and just transition, particularly in connecting local retrofit needs with EU frameworks such as Fit for 55 and the Social Climate Fund. Strengthening metropolitan capacity will be essential to consolidate equitable and climate-aligned renovation pathways in the years ahead.
