The report evaluates 17 types of natural infrastructure across four functional families (cover, basins, watercourses, and groundwater) to support water management in the Canadian Prairies. It argues that while natural assets like grasslands and wetlands are essential, constructed analogues such as bioretention and green roofs are necessary in urban areas to bridge the infrastructure gap. The document provides performance rankings and technical data to help decision-makers build a more robust business case for nature-based solutions over traditional grey infrastructure.

The document examines how the High Line's vegetation helps alleviate urban heat islands (UHIs), which are areas of elevated heat caused by population density and the built environment. It notes that while human-caused climate change warms the planet, urban infrastructure amplifies average and extreme temperatures, disproportionately affecting underserved populations. The report focuses on the role of trees and plants in urban spaces as a solution to these heat-related health and quality-of-life threats.

The briefing outlines five key heat metrics—land surface temperature, air temperature, heat index, wet bulb globe temperature, and thermal comfort indices—detailing their specific uses and limitations. It argues that while traditional metrics are useful for regional analysis and safety limits, thermal comfort modeling is essential for understanding human-scale heat exposure and designing local interventions like shade and wind corridors. The document provides a framework for matching these metrics to goals such as protecting pedestrians, reducing energy use, or lowering citywide temperatures.

GreenLatinos' 2025 Impact Report details a year of advocacy against federal environmental rollbacks and the implementation of community-led resilience projects. Key achievements include securing $10B in Proposition 4 funds in California, passing the Clean and Reliable Grid Affordability Act in Illinois, and managing over $30 million in funding for urban forestry and community grants. The organization mobilized over 250 environmental justice organizations to respond to EPA rollbacks and expanded its 'Climate Lotería' project to combat Spanish-language climate disinformation. Its Urban Greening Initiative diverted over 611,000 pounds of organic waste and planted hundreds of trees across Chicago, Los Angeles, and Albuquerque.

The report highlights 'bright spots' in Canada where local governments are integrating natural infrastructure—such as wetlands, trees, and rain gardens—to complement traditional grey infrastructure for services like stormwater management and flood protection. It examines the City of Nelson's use of bylaws, Halifax Regional Municipality's policy embedding, and EPCOR's integrated investment strategy in Edmonton.

The report examines how the City of Nelson, Halifax Regional Municipality, and EPCOR integrate natural infrastructure into their water management. It highlights the use of local bylaws in Nelson, a multi-level policy hierarchy in Halifax, and a hybrid grey-natural approach by EPCOR in Edmonton to enhance climate resilience and flood mitigation.

WRI Indonesia's Cities4Forests initiative helped Jakarta implement two new regulations in 2021 regarding tree management and park provision. This collaboration led to the creation of 54 new urban parks since 2022 and the planting of over 65,000 urban trees, specifically targeting underserved areas to mitigate air pollution, extreme heat, and flooding.

Urban trees in the U.S. provide critical benefits to the 80% of the population living in cities, which are otherwise prone to heat and flooding due to dense infrastructure. While an estimated 5.5 billion urban trees support city resilience, these forests require stewardship to survive the pressures of urbanization and a warming climate.

The briefing highlights the economic and environmental value of urban nature—such as forests, street trees, and wetlands—as a tool for climate mitigation and adaptation. It asserts that the global value of urban nature's benefits is nine times its costs and provides specific examples from Sacramento, Ahmedabad, and Curitiba to demonstrate how nature-based solutions can reduce building energy demand, lower the carbon footprint of stormwater management, and decrease transportation emissions. The document concludes by calling for an increase in annual investment in urban nature projects from $32 billion to $135 billion by 2030 to realize an estimated $2 trillion in annual net benefits.

The briefing examines the impact of extreme heat and the urban heat island effect in Delhi, highlighting that the city is ranked as the second most heat-stressed city globally. It proposes that while Delhi has significant green space, including 18,000 parks and the Central Ridge, much of it is underutilized or dominated by invasive species like Prosopis juliflora. The author advocates for a transition from emergency heatwave planning to long-term nature-based solutions, specifically through the planting of locally adapted native species tailored to specific micro-habitats. The document provides five recommended practices for maximizing ecosystem health, emphasizing the need for a scientific species selection framework and the prioritization of greening in low-income, high-density neighborhoods to address heat equity.

The Inflation Reduction Act commits $369 billion to energy and climate initiatives to decarbonize the US economy and secure clean energy supply chains. Key measures include tax credits for electric vehicles, residential energy efficiency, and green hydrogen, alongside funding for urban forestry and carbon capture. The legislation targets a reduction in energy costs for households, the revitalization of former fossil fuel communities, and the acceleration of low-carbon industrial production in sectors like steel and cement.

The report argues that forests are vital to human health through three primary functions: provisioning (food, water, medicinal plants), prevention (reducing zoonotic spillover and buffering natural hazards), and healing (reducing risks of noncommunicable diseases). It highlights how deforestation and degradation trigger negative health cascades, such as increased disease spillover and higher exposure to pollution and extreme heat. The document advocates for a systems approach to forest conservation, integrating public health and environmental sectors to protect intact forests, improve working land management, diversify restoration, and create urban forests.

Climate Central developed an Urban Heat Intensity Index for 159 U.S. cities, finding that New Orleans, Newark, New York City, Houston, and San Francisco have the highest intensity scores. The report identifies albedo, lack of greenery, population density, and building height as primary drivers of the UHI effect. These conditions exacerbate heat waves, worsen air quality through ground-level ozone formation, and disproportionately affect vulnerable populations, particularly those in formerly redlined neighborhoods. Proposed solutions include short-term emergency cooling measures and long-term infrastructure changes such as planting trees, installing green and cool roofs, and deploying solar energy.

The document details the activities of the Wisahkotewinowak collective in the Waterloo-Wellington region of Ontario, illustrating how Indigenous-led urban gardening and land restoration contribute to climate adaptation and reconciliation.
