GRADE

Grants to Replace Aging Diesel Engines

In 2007, Mecklenburg County Air Quality launched an innovated air quality improvement program called Grants to Replace Aging Diesel Engines or GRADE.  GRADE is designed to reduce oxides of nitrogen (NOx), an ozone forming air pollutant, by providing businesses and organizations funding incentives to replace or repower heavy-duty non-road equipment with newer, cleaner, less polluting engines.

Since its inception, GRADE has funded over 367 projects and awarded over $8.2 million. These projects have reduced over 1,348 tons of ozone-forming NOx in the Charlotte region.  Visit our Interactive GRADE Story Map.
