Find out how much one new landscaped space can make a difference with our Clean Air Calculator.This interactive tool lets you map green spaces—lawns, trees, shrubs, gardens—and instantly see their measurable impact on the environment.
The Clean Air Calculator reveals the tangible environmental benefits of green spaces by estimating how much carbon dioxide is sequestered, how much oxygen is produced, and how many people benefit from cleaner air—right in your own community.
Developed through the Canadian Nursery Landscape Association’s Climate Adaptation Committee, this tool uses ArcGIS mapping software to visualize the environmental value of urban greenery.
The underlying science draws from government and academic research, including the U.S. Forest Service, University of Guelph, and Natural Resources Canada.It’s designed for everyone—from students to city planners—to understand, in clear and simple terms, how green spaces make cities more livable.
Use the Clean Air Calculator to visualize your landscape’s impact
in real time. Every plant matters—whether it’s a single tree in your yard
or a city park filled with greenery.
The calculator estimates clean air volume based on the oxygen produced by plants each year. Clean air refers to air with no harmful levels of pollutants or chemicals—essential for human and environmental health.
While every effort has been made to ensure the accuracy of this calculator, results are estimates and should be used as a guide only.This tool is not a substitute for formal professional advice and should not be relied upon as the sole source of environmental data.
