What is Green Heart Louisville?

With a multimillion-dollar investment in underserved Louisville neighborhoods, the Green Heart Project seeks to demonstrate the scientific link between nature and human health. By tackling two critical problems – air pollution and chronic disease – with a new, nature-based approach, Green Heart hopes to create a platform for major change. The project is a clinical trial where trees are the medicine. What we learn in Louisville could improve the lives of thousands of people and potentially millions or billions worldwide.
