Green Cities Foundation invites members to map their impact and take part in the Plants Love You Clean Air Giveaway.


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).

Plants Are The Lungs of our Communities.

An aerial concept rendering showing how managed green spaces function like lungs for the built environment, filtering air, storing carbon, and improving local conditions. Visualized using the Clean Air Calculator to demonstrate the measurable impact of plants at scale.
It takes less than five minutes to understand the environmental value your plants are providing. 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.

Alan White, CNLA Vice President & Chair of the Climate Adaptation Committee.

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. Discover your impact today with the Clean Air Calculator and see just how much your plants love you back.

The campaign runs nationwide through 2025–2026 under a simple message: Every plant makes a difference.
