This report examines the implementation of nature-based solutions (NbS) for municipal stormwater management in Sweden. It finds that while NbS principles are widely embedded in municipal planning, they are rarely called by that specific name. Key barriers to adoption include a lack of standardized cost data—especially for operations and maintenance—and a failure of policy frameworks to fully account for the multiple co-benefits of NbS. The report recommends standardizing cost libraries, clarifying stakeholder responsibilities, and broadening the focus of co-benefits to include heat island reduction and carbon sequestration.

This executive summary describes natural infrastructure approaches in Canada, highlighting how wetlands, trees, and rain gardens can complement traditional grey infrastructure to deliver municipal services like stormwater management and flood protection. It presents three 'bright spots'—the City of Nelson, Halifax Regional Municipality, and EPCOR—as illustrative models of implementation across different administrative and geographic contexts.

This report by the International Institute for Sustainable Development (IISD) examines "bright spots"—effective examples of policy and planning change—to scale natural infrastructure for water services in Canada. It analyzes three distinct models: the City of Nelson's use of local bylaws, the Halifax Regional Municipality's integrated multi-level planning, and EPCOR's hybrid approach combining natural and grey infrastructure for flood mitigation in Edmonton.

This briefing by RMI argues that integrating urban nature—such as forests, street trees, and bodies of water—into city planning reduces greenhouse gas emissions, lowers energy costs, and improves equity. The document highlights that the global value of urban nature's benefits is nine times the costs, and it calls for a significant increase in annual investment to reach a potential $2 trillion in annual net benefits by 2030.

This report presents a Sustainable Asset Valuation (SAVi) assessment of three stormwater infrastructure options in the Paterson Park Precinct of Johannesburg, South Africa: a grey concrete culvert, a nature-based stream renaturalization, and a hybrid solution. Using data from the Copernicus Climate Change Service (C3S), the study compares these options through an integrated cost-benefit analysis (CBA) and climate change scenario analysis over 20- and 40-year horizons. The findings demonstrate that nature-based infrastructure is the most cost-efficient and climate-resilient choice, providing significant co-benefits in flood mitigation and water supply.

The City of Columbia, South Carolina, issued a USD 37.9 million Certified Climate Bond on December 19, 2018, to finance and refinance stormwater assets. This issuance represents the first Certified Climate Bond from a US local government outside of New York and California, and the first in South Carolina.

This fact sheet details a CNY400m (USD59m) private placement green bond issued by Chongqing Qianjiang Urban Investment on September 21, 2018, to fund stormwater infrastructure in Chongqing, China.

The City of Tampa, Florida, issued a USD 84.6 million green bond on April 26, 2018, to finance stormwater management and pollution reduction projects.

This research paper examines technology and financing options for urban stormwater management, specifically focusing on the use of stormwater markets to incentivize private investment in decentralized green infrastructure.

This report by the International Institute for Sustainable Development (IISD) examines the causes and impacts of urban stormwater runoff and evaluates various governance and financing mechanisms to manage it. The authors contrast traditional 'gray' engineered infrastructure with 'green' infrastructure (GI) and propose the development of stormwater markets—specifically through allowance trading and credits—to attract private investment and reduce the financial burden on public utilities.

This fact sheet from the Environmental and Energy Study Institute (EESI) describes various cool roof technologies—including naturally cool, coated, insulated, and green roofs—and their benefits for energy efficiency, climate mitigation, and urban environment management.

This 2006 report by the Rocky Mountain Institute (RMI) for the Cuyahoga County Planning Commission outlines a strategy to integrate environmental restoration with economic development along the Cuyahoga River ship channel in Cleveland. It proposes a transition from traditional industrial land use to a 'restoration economy' through projects focusing on stormwater management, aquatic habitat restoration, brownfield remediation, green industrial building standards, and industrial symbiosis (Waste = Revenue).

This document is a technical annexure for the Yzermyn Underground Coal Mine, detailing the design and infrastructure for water use authorisation. It covers the construction of the adit platform, administration and workshop facilities, sewage and water treatment plants, waste management, and a comprehensive stormwater management plan designed to separate clean and dirty water.

The "Linnaelustiku käsiraamat" (City Wildlife Handbook), published by the Stockholm Environment Institute (Tallinn Center) in 2010, is a comprehensive guide designed for environmental specialists, landscape architects, officials, and citizens. It provides practical methods for maintaining and increasing biodiversity within urban environments, including gardens, parks, and buildings, specifically tailored to the conditions in Estonia.
