Quality parks and green spaces are integral to healthy, equitable and environmentally sustainable communities. Our research identifies how urban greening can build resilience to climate change, with a focus on supporting equitable access to parks, nature and green infrastructure for low-income populations and communities of color. 

Our Research

Public Parks

Parks can reduce greenhouse gas emissions, cool down cities, and improve air and water quality – all while supporting healthy, livable communities. Our research helps maximize these benefits of parks, particularly in neighborhoods with limited green space.

Complete and Living Streets

Complete streets prioritize safety and mobility for all, especially pedestrians and cyclists. Our toolkits help design streetscapes that are people-focused and environmentally sustainable.

Green Infrastructure

The built environment plays an important role in managing water quality and cleaning stormwater before it enters local waterways. Our research helps to expand green infrastructure, like rain gardens and permeable pavements, to create healthier urban ecosystems.
