2027 Cohort · The partnership

Turning cities’ clean air ambition into action

Clean Air Capitals works with a small group of cities to develop ambitious, durable indoor clean-air projects for students and schools—and become national exemplars in this work. Our goal is to work with this inaugural cohort in 2027—and perhaps beyond—to make clean air in classrooms a reality in these cities, demonstrating what is possible when existing assets are brought together.
