Milton, Ontario, Nov. 30, 2025 (GLOBE NEWSWIRE) — The Green Cities Foundation (GCF), in collaboration with the Canadian Nursery Landscape Association (CNLA), has unveiled the Clean Air Calculator. This interactive tool helps Canadians see the environmental impact of their green spaces.
Built on verified scientific data, the calculator estimates the amount of carbon dioxide sequestered, oxygen produced, and clean air generated by trees, turf, and shrubs in residential and community areas. This user-friendly tool offers a fast and engaging way to see how individual green spaces contribute to cleaner air and healthier, cooler neighbourhoods.
To mark the launch, GCF has introduced the “Plants Love You Clean Air Giveaway,” inviting Canadians to map their green spaces for a chance to win one of two $500 gift cards to a local independent garden centre (excluding Quebec).
How to Enter:
- Create a Clean Air Calculator account, cleanaircalculator.ca/register
- Map the impact of your green space with the Clean Air Calculator, cleanaircalculator.ca/
- Share the impact of your green space on social media.
- Add your email to enter the giveaway at woobox.com/yxfj5g.
“It takes less than five minutes to understand the environmental value your plants are providing,” said Alan White, CNLA Vice President and Chair of the Climate Adaptation Committee. “Plants are one of the most accessible forms of climate technology we have; they are the lungs of our communities. When we make our green spaces visible in the data, communities are better equipped to protect them and invest in more.”
Every entry supports GCF’s mission to determine the impact of our collective green spaces and to encourage more community greening projects across Canada to connect plants and people for a cleaner, healthier urban climate.
The campaign runs nationwide through 2025–2026 under a simple message: Every plant makes a difference.
