Landscape and lawn care professionals now have a new resource to highlight the environmental benefits of the green spaces they design and maintain.
On Earth Day 2025, Project EverGreen launched the Clean Air Calculator. This easy-to-use online mapping tool measures how green spaces such as lawns, athletic fields, golf courses and parks sequester carbon, offset vehicle emissions and contribute to cleaner air.
This tool is tailored for professionals working with turf, trees and shrubs, including landscape contractors, lawn care specialists, sports field managers and golf course superintendents. It equips them with data to illustrate the ecological benefits of their projects.
“Green industry professionals are on the front lines of environmental stewardship,” said 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.”
With an interactive map, users can trace the boundaries of any property — be it a residential lawn, schoolyard, park, sports field or golf course — and instantly receive a Clean Air Score. This score reveals how much carbon is captured, how much air pollution is filtered out and how much oxygen is generated, all in comparison to the surrounding areas.
For professionals overseeing multiple properties or expansive landscapes, the calculator serves as an essential resource for educating clients, sustainability reporting and community outreach. It also offers a powerful way to emphasize the vital role of natural grass and healthy landscapes in both urban and suburban settings.
