Clean air, healthy fields was the clear message delivered at the 2026 Sports Field Management Association’s Annual Conference in Fort Worth, Texas, where Project EverGreen Executive Director Cindy Code and immediate past president Scott Bills of Sports Field Solutions reminded sports field managers that natural grass fields are living systems that deliver measurable environmental value – value that can now be clearly quantified.

That’s where Project EverGreen’s Clean Air Calculator (CAC) comes in.

Developed as a science-based tool, the Clean Air Calculator translates the environmental benefits of professionally managed natural turf into data that administrators, school boards, municipalities, and community stakeholders can understand and trust. In an era where sustainability expectations are rising and budgets require justification; the CAC gives sports field managers the numbers they need to advocate for natural grass and proper maintenance.

Turning Turf Management into Environmental Data

Sports field managers already know the benefits of healthy turf. Grass sequesters carbon, produces oxygen, cools surrounding areas, and contributes to safer, more playable fields. What the Clean Air Calculator does is make those benefits visible.

Using peer-reviewed research from institutions including The Ohio State University, Texas A&M, and the Soil Health Institute, the CAC measures:

• Carbon sequestered annually
• Clean air produced each year
• Equivalent miles of vehicle emissions offset
• The number of people benefiting from oxygen production

For example, just 5,000 square feet of healthy grass can produce enough oxygen to support more than a dozen people per day, depending on location. When applied across athletic fields, campuses, or park systems, the environmental impact quickly becomes significant

A Stronger Case for Natural Grass Fields

Sports field managers are often asked to defend natural turf against synthetic alternatives, especially when decision-makers focus on usage hours or short-term convenience. The Clean Air Calculator helps shift that conversation.

Rather than framing grass as a “green space,” the CAC positions it as environmental infrastructure. The healthier the turf, the greater the environmental return. Properly managed fields don’t just perform better – they actively contribute to sustainability goals, including Environmental, Social, and Governance (ESG) initiatives now required by many schools, municipalities, and institutions.

With CAC data in hand, field managers can demonstrate how investment in aeration, irrigation, fertility, and professional oversight supports both field safety and environmental outcomes.

“Sports field managers have always known that natural grass fields do more than host games – they improve communities,” Bills told attendees. “What the Clean Air Calculator does is turn that belief into credible, science-backed data. It gives managers the confidence to walk into any budget meeting and clearly show that healthy turf is not an expense – it’s environmental infrastructure.”

A Tool for Communication and Advocacy

One of the CAC’s most powerful benefits is its role as a storytelling tool. It converts technical data into public-facing language that resonates beyond the industry.

Statements like “This field cleans the air for 178 people annually” or “Offsets the equivalent of 250,000 miles driven each year” help non-experts understand the value of natural grass quickly and clearly. That clarity improves credibility, strengthens budget discussions, and supports long-term turf preservation.

Benefits Beyond Sports Fields

While the CAC is especially valuable for sports field managers, its applications extend across the green industry.

• Landscape contractors can use CAC reports to show clients the environmental return of professionally managed properties.
• Lawn care professionals can demonstrate how healthy residential and commercial turf contributes to cleaner air and reduced carbon impact.
• Golf course superintendents can quantify the environmental value of managed acreage and support sustainability reporting.
• Municipal parks departments can align park maintenance programs with ESG goals and community health initiatives.

In every case, the tool reinforces the same message: healthy, well-managed green spaces deliver benefits that extend far beyond aesthetics.

Start Small. Think Big.

Project EverGreen encourages professionals to start with one field, one property, or one park. Use the Clean Air Calculator in a single meeting. Share one result. Those small steps help elevate the profession, strengthen advocacy for natural turf, and position green industry professionals as environmental leaders.

Because when you maintain grass, you’re also maintaining clean air.
