Buildings are essential to society but contribute significantly to climate change, accounting for about 40% of carbon emissions. With urban areas expanding and many structures remaining, retrofitting is vital, yet the current rate is only 1% annually due to high costs. Bankers without Boundaries promotes a place-based approach to consolidating homes into larger projects, enhancing their appeal for investment. 

Initiatives like the ‘Net Zero Neighbourhood’ model and the Climate City Capital Hub aim to attract private financing. Successful retrofitting requires blended finance solutions and building local capacity to facilitate climate resilience and community engagement.
