The Banking on Green report focuses on the economic impacts caused by polluted urban runoff, also known as “stormwater,” and the co-benefits of energy reduction, flood mitigation, and improved public health outcomes. The report provides case studies and examples which highlight instances of how green infrastructure can provide cost-effective adaptation solutions. Green Infrastructure (GI) can help increase energy efficiency with green roofs and reduce heating and cooling costs. Additionally, GI practices that capture, infiltrate, and reuse rainwater can reduce the energy needed to pump and treat drinking water and wastewater.
