Mattamy thinks long term. Our homes and communities are designed to meet the needs of current and future generations. We employ products and processes that aim to improve the way our homes use energy and resources while also reducing GHG emissions from our activities. We are focused on measuring and understanding our homes’ whole-building life cycle and using that knowledge to successfully implement our carbon-reduction strategy.

Hitting Our Decarbonization Targets

In FY2025, for the first time since launching our company-wide decarbonization efforts, Mattamy reduced GHG emissions across our operations by 10% from code. This milestone achievement was made possible first by the effort, innovation and commitment of Mattamy’s people. It was supported by an organization-wide focus and a regional approach that enabled each operation to utilize its unsurpassed knowledge of local codes and conditions, including underlying utility infrastructure and weather patterns, to develop a GHG reduction strategy tailored to its respective market. Another essential element of our progress was Mattamy’s investment in understanding the nature of the emissions and carbon generated by our activities.

UNDERSTANDING SCOPES 1, 2 AND 3

We quantify our GHG emissions inventory according to the GHG Protocol Corporate Standard.

Scope 1:

Direct GHG emissions from sources owned or controlled by Mattamy (e.g., fuels we purchase for our vehicle fleet or to warm homes under construction in the winter months).
Scope 2:

Indirect GHG emissions from electricity, steam, heating and cooling purchased by Mattamy (e.g., electricity used for our offices, sales centres and construction site trailers).
Scope 3:

GHG emissions that result from our activities but occur from sources not owned or controlled by Mattamy (e.g., our homes’ long-term operation, purchased goods and air travel).
