Every day is Earth Day for Project EverGreen. Earth Day is a powerful reminder of our shared responsibility to care for the planet. At Project EverGreen, that responsibility isn’t limited to a single day – it drives our work every day. Our focus is simple: create and sustain healthy green spaces that benefit people, communities, and the environment.

From Awareness to Action and Now, Measurement

Lawns, landscapes, parks, and managed green spaces are more than aesthetic. They actively:

Sequester carbon
Improve air quality
Reduce urban heat
Manage stormwater
Support healthier communities

What’s new and critical is the ability to measure that impact in real terms. That’s why Project EverGreen developed the Clean Air Calculator.

The Clean Air Calculator translates green space into tangible environmental benefits: quantifying carbon sequestration, clean air production, and the number of people positively impacted. It turns something people value into something they can see, understand, and advocate for.

Because protecting green space is no longer just about belief, it’s about proof.

Supporting Military Families Through GreenCare for Troops

Environmental stewardship and community support go hand in hand. Through GreenCare for Troops, lawn and landscape professionals volunteer their services to maintain outdoor spaces for military families with a deployed service member. The impact is immediate and meaningful:

Reduces stress for families
Maintains safe, usable outdoor spaces
Ensures landscapes continue delivering environmental benefits

Healthy, maintained lawns don’t just look better, they function better for families and the environment alike.

Revitalizing Public Spaces Through GreenCare for Communities

Across the country, Project EverGreen transforms underperforming parks, athletic fields, and shared green spaces into thriving community assets. These projects go beyond visual improvement and deliver the following:

Restore soil and turf health
Introduce sustainable landscaping practices
Create cooler, safer, more functional environments

And increasingly, tools like the Clean Air Calculator help demonstrate the long-term environmental return of these investments.

A Collective Effort with Real Results

This work is powered by a network of partners, volunteers, and industry professionals committed to a common goal: advancing environmental stewardship through action. Together, we’re not just improving spaces. We’re elevating the conversation around the value of green spaces by pairing on-the-ground impact with measurable outcomes.

Beyond Earth Day

Earth Day sparks awareness. But lasting change requires consistency and accountability. At Project EverGreen, every day is Earth Day. And today, we’re doing more than acting – we’re quantifying the difference healthy green spaces make.

More About the Clean Air Calculator

What is the Clean Air Calculator?

The Clean Air Calculator is a tool that measures the environmental benefits of green spaces including lawns, landscapes, parks, sports fields, golf courses and more.

How does the Clean Air Calculator work?

The Clean Air Calculator is a web-based mapping tool that measures the positive environmental impact of plants – specifically lawns, trees and shrubs – on a property. The Clean Air Calculator combines geographic information system (GIS)-based interactive maps with a scientific data model to identify the value of actual green space in cities, neighborhoods, communities and individual properties. After the mapping is completed, the tool tallies the measurements and estimates the environmental benefits of that property.

Who can use the Clean Air Calculator?

Anyone! Homeowners, service professionals, schools, municipalities, parks can all benefit from using the Clean Air Calculator, to name a few.
