At Mattamy, sustainability isn’t a trend – it’s a core value. From the day we were founded more than 47 years ago, we’ve embraced our responsibility to our employees, homeowners, partners, communities and the planet.

Our third annual Sustainability Report shares the story of how we’ve turned ambition into action and action into accomplishment. At a time when many organizations are rethinking their commitments, Mattamy is pushing forward – embedding sustainability across our business and leading the homebuilding industry in climate action and accountability.

This year’s Report showcases several major milestones, including:

Surpassing our target of a 10% reduction in GHG emissions
Establishing North America’s first sustainability-linked revolving loan in the homebuilding sector
Positioning ourselves to become the first North American homebuilder to obtain limited assurance on select GHG metrics

Inside the Report, you’ll find:

Executive messaging and strategic insights
Our approach to materiality
Updates on our sustainability pillars and FY25 achievements
Performance data and metrics

The Report also features real-world stories from across our business – from low-carbon construction to biodiversity initiatives to community engagement – that highlight the passion and creativity of our team members.

We invite you to read the Report and learn more about how Mattamy is helping build a better world.
