Project EverGreen launches Clean Air Calculator

Landscape and lawn care professionals now have a new tool to showcase the environmental value of the green spaces they create and maintain.

To celebrate Earth Day earlier this month, Project EverGreen launched the Clean Air Calculator, an online mapping tool that measures how green spaces such as lawns, athletic fields, golf courses and parks sequester carbon, offset vehicle emissions and contribute to cleaner air.

The tool is designed for professionals who work with turf, trees, and shrubs, providing them with data to demonstrate the ecological impact of their work.

“Green industry professionals are on the front lines of environmental stewardship,” says Cindy Code, executive director of Project EverGreen. “The Clean Air Calculator allows them to quantify their contributions in real, measurable ways – and communicate the value of well-maintained green spaces to clients, communities, and stakeholders.”

Using an interactive map, users can outline the area of any property, whether it's a single-family lawn, schoolyard, park, sports field or golf course, and receive an instant Clean Air Score. This score details how much carbon is sequestered, how much air pollution is removed and how much oxygen is produced compared to surrounding surfaces.

For professionals who manage multiple properties or large landscapes, the calculator becomes a valuable tool for client education, sustainability reporting and community outreach. It also provides a compelling way to reinforce the importance of natural grass and healthy landscapes in urban and suburban environments.
