The LIFE+ Climate proofing social housing project has delivered packages of low-cost retrofit climate change adaptation measures across three social housing estates in the London Borough of Hammersmith & Fulham. By targeting social housing estates the project has helped to reduce these relatively deprived communities’ vulnerability to climate change. The project has focussed on green infrastructure based approaches, recognising the potential such measures have for increasing communities’ resilience to climate change whilst also delivering multiple other benefits, including improvements in biodiversity, visual amenity, play provision, local food production and air quality. The project is co-financed by the EU LIFE programme, which supports pilot or demonstration projects that contribute to the implementation, update and development of EU environmental policy and legislation. For this project the innovation is not a technological one. The innovation is in demonstrating how known green infrastructure techniques, with their many benefits, can be retrofitted on a large scale into existing social housing estates. This will be vital if we are to increase our resilience to climate change because focusing on new build alone will not deliver the scale or speed of change required.
