Louisville’s air quality ranks among the worst in Kentucky and the city has high rates of heart disease.
And our current tree canopy is only 37% and decreasing.
Green Heart Louisville is studying the impact of better air quality on heart disease through urban greening.

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.
