When development occurs in an urban setting, the natural landscape is displaced with mostly non-permeable surfaces. The Edmonton Ecoroof and Climate Change Resiliency Initiative will assess the impacts a critical mass (minimum number) of ecoroofs needed for the City of Edmonton to increase resilience to climate change and develop a policy program to educate and incentivize increased implementation of ecoroofs.

Green roofs, or ecoroofs, have a number of benefits including stormwater management, biodiversity and habitat contributions, reduction of urban heat island effect, reduced carbon footprint, energy savings, urban agricultural opportunities, and air quality mitigation – to name a few. Many of these ecoroof benefits could potentially contribute to climate change resiliency and other public benefits but are not widely used in Alberta.

In collaboration with the City of Edmonton, the Miistakis Institute will: analyze the impacts ecoroofs have on air quality, water quality and quantity, biodiversity, energy savings, wildlife habitat, the urban heat island effect, quality of life and economy in the context of climate resiliency. Successful incentive and policy programs in other jurisdictions will be evaluated, and these findings will be applied to Edmonton’s context in order to promote the installation of ecoroofs – should they prove beneficial.

Guided by the City of Edmonton’s Climate Change Strategy, the research team will complete the conceptual analysis of a ‘critical mass’ of ecoroofs on climate resilience in the short term. This builds off an initiative already underway, and ensures the methodology for the ecoroof project aligns with the Climate Change program. The long term project impact will be measured by indicators including the area of green roofs installed, litres of stormwater diverted, cumulative tonnes of GHGs avoided, KW hours of energy saved per year, new employment, and increased biodiversity and habitat.
