Our Performance in 2024

At the same time, our expertise in sustainable construction

has continued to f lourish to meet our clients’ growing needs.

Whether it’s mastering the use of lower-carbon materials like

concrete, steel and wood, accounting for and offsetting GHG

emissions during design and construction or overseeing life

cycle analyses and sustainable certif ication, our know-how is

rapidly evolving.

Including projects carried out through joint ventures and those of

our subsidiaries, we’re currently leading 185 sustainable projects,

which account for 70% of our revenue. These are projects that aim

for sustainable certif ication, that help mitigate climate change,

such as public transit systems and renewable energy production

facilities, or that use low-carbon materials like mass timber. Our

teams are currently working on nine mass-timber constructions,

including Canada’s highest tower at the University of Toronto.

We reached an important milestone this year. For the f irst time,

we reduced the absolute value of our Scope 1 and Scope 2 GHG

emissions, despite an increase in our operations. How? Through

innovative actions and the engagement of our teams on site.

Let’s start with temporary heating inside the buildings under

construction, which accounts for 50% of our annual emissions.

Mild temperatures may have played a role, but our Heat Better

Challenge, launched in 2023, definitely made a difference. In

2024, we made the use of smart temporary heating units man-

datory for all our building projects. This equipment optimizes

energy use while maintaining ideal conditions for the work

to be done. Double advantage: better quality and a reduced

carbon footprint.

We’ve also started to electrify our worksite vehicle f leets, which

generate about 15% of our Scope 1 emissions. The initial com-

ments from the people who use these vehicles are encouraging

and helpful, allowing us to f inetune our plan and continuously

improve our electrif ication strategy.

To go even further, we conducted our f irst comprehensive inventory

of Scope 3 emissions. This in-depth analysis of our value chain

emissions gives us a clear and comprehensive picture of our car-

bon footprint and will facilitate our collaboration with our clients,

partners and suppliers to reduce our impact in the future.
