Historically, like most urban infrastructure, green infrastructure has been the responsibility of local governments. Green infrastructure is rarely seen a priority for local governments because its value is not always obvious or quantifiable. Growing pressure on municipal budgets, and many competing priorities for funds, has decreased the focus on green infrastructure. An additional challenge for local governments to scale the implementation of green infrastructure is the ability to invest in it in the first place, as green infrastructure depends almost entirely on public financing.
The biggest roadblock for implementing and scaling green infrastructure is the financing. We urgently need innovative financing solutions that will alleviate the financial burden of the public sector by strategically involving the private sector. The private sector can drive the uptake of green infrastructure through capital investments and implementation support, while reaping the social, environmental, and financial benefits. These actions from the private sector can help mainstream infrastructure that is smart, sustainable, and resilient to a changing climate.
