This brief explores innovative approaches to building sustainable and climate-resilient cities through green infrastructure. It examines how urban vegetation can reduce heat island effects, improve air quality, and enhance carbon sequestration, while highlighting the role of green building design and energy-efficient development in improving environmental performance. The brief also addresses climate adaptation, biodiversity conservation, sustainable infrastructure, environmental governance, and policy frameworks that support resilient urban systems and sustainable urban growth. Designed for planners, architects, policymakers, researchers, and sustainability professionals, it provides practical insights and evidence-based solutions for creating healthier, more resilient, and environmentally responsible urban communities.

Dr Mary J. Thornbush is a researcher specializing in urban sustainability, climate change mitigation, and nature-based solutions for resilient cities. Her work focuses on the environmental and policy dimensions of sustainable urban infrastructure, with particular expertise in green roofs and their role in addressing the challenges of urbanization and climate change. Through her research, she explores how municipalities can integrate innovative green infrastructure into planning and governance frameworks to enhance environmental performance, strengthen urban resilience, and improve the quality of life for city residents.
