Why We’re Doing This

Our vision is to expand what is possible, together, for a better future.

“Climate action is a defining part of how buildings are planned, designed, and operated. At HH Angus, we’re committed to helping our clients reduce carbon, improve resilience, and make informed decisions that create lasting value—while continuing to strengthen the sustainability of our own operations.”

Paul Keenan, President

This report underscores our commitment to controlling our broader climate emissions impact as we publish this data and work to reduce our carbon footprint as a company.

Our Progress

Following the achievement of our 2024 emissions reduction target, HH Angus continued to make progress in 2025. Emissions intensity decreased by a further 3.7%, from 3,704 kg CO₂e per employee in 2024 to 3,566 kg CO₂e per employee in 2025, resulting in an overall reduction of 10.7% from our 2023 baseline.

We expect to achieve similar emissions reduction into the future as we continue to drive down our greenhouse gas emissions.

Understanding Our Emissions

Understanding where our emissions come from helps us identify where we can have the greatest impact. In 2025, our operational emissions came primarily from purchased goods and services, employee commuting, business travel and the operation of our offices.

HH Angus Corporate Initiatives

To reduce the environmental impact of our operations, HH Angus continues to implement initiatives that support more efficient workplaces, responsible resource use and employee engagement.

Green
Commuting

Supporting lower-impact commuting and transit-accessible workplaces.

Internal Education Campaign

Newsletters, coffee chats and other initiatives that build awareness and employee engagement.

More Energy-Efficient Offices

Lighting occupancy sensors, transit-accessible locations and smart sensor initiatives.

Staff-Driven Initiatives

Tree Canada plantings, local recycling events, park cleanups and energy conservation events.

Green Ride-Sharing for Business Travel

Encouraging more efficient transportation choices for business travel.

Donating Equipment

Retired computer equipment is donated through organizations supporting reuse and community access to technology.

Our Work

Every project presents an opportunity to reduce environmental impact and improve long-term resilience. Across Canada, HH Angus continues to help clients deliver high-performance, low-carbon facilities that advance their sustainability objectives. Here are a few recent examples.

Ontario Power Generation
Oshawa Headquarters

An award-winning adaptive reuse project that transformed an existing office building into a modern, energy-efficient corporate headquarters, reducing embodied carbon while extending the life of the building.

Ferme

La ferme Opercule

Canada's first urban commercial fish farm, an award-winning project, uses innovative recirculating aquaculture technology to dramatically reduce water consumption while supporting sustainable local food production.

Montréal Metropolitan
Airport Terminal

A fully electrified passenger terminal designed to improve energy performance, reduce operational emissions, and support the future of sustainable regional aviation.

Why We’re Doing This

Our vision is to expand what is possible, together, for a better future.

“We’re working to build a better, more sustainable business from the inside. Our climate action isn’t just about carbon, it’s about reducing waste, improving efficiency, and creating long-term value for our people and operations.” Paul Keenan, President

This report underscores our commitment to controlling our broader climate emissions impact as we publish this data and work to reduce our carbon footprint as a company.

Our Target

After calculating our 2023 emissions baseline, we set a target to reduce 2024 emissions by 5% per category per employee. We’re proud to report a 7.4% reduction was achieved.

How did we
do in 2024?

Here’s a breakdown of our
emissions by category:

The Bayers Lake Community Outpatient Centre was recently honoured as a Gold Winner by the 2024 Urban Design & Architecture Design Awards.

 

The project was recognized for innovation and design excellence. The Outpatient Centre is part of a $2-billion P3 redevelopment of the QEII Health Sciences Centre in Halifax, Nova Scotia. HH Angus, in affiliation with Dillon Consulting, provided mechanical engineering, fire protection and plumbing design to the 134,000 ft2 project, which was led by the EllisDon Infrastructure Healthcare Consortium. The design team was led by Parkin Architects and FBM Architects.

A vital community resource, the Outpatient Centre provides essential ambulatory care closer to patients residing outside the Greater Halifax Region. Anticipating 28,000 clinic visits and 30,000 x-ray and blood collection visits per year, the Centre provides a range of patient services that do not require a hospital setting. These include initial visits with specialists, post-surgery and post-treatment follow-up, blood collection, eye care clinic, physio and occupational therapy, diabetes and orthopedic assessments, rehabilitation services, 17 examination rooms, 24 dialysis stations, and diagnostic imaging (x-rays and ultrasounds).

Infrastructure Ontario (IO) and Children's Hospital of Eastern Ontario (CHEO) have announced the shortlisted teams to design, build and finance the 1Door4Care: CHEO Integrated Treatment Centre project in Ottawa.

HH Angus is providing Mechanical Engineering consulting services as part of the EllisDon Infrastructure Healthcare team which was named as one of the three teams moving on to the RFP stage for this project. The new facility will merge seven care locations into a single, state-of-the-art, purpose-built site on CHEO’s main campus and will include multi-use clinic space, a physiotherapy rehab gym, expanded mental health clinics, indoor and outdoor space where teachers and therapists combine education and therapy, secure space for children who have been abused, modern treatment rooms for kids with behavioural needs, advanced technology to enable virtual care, a physical link to the main building on campus, family support spaces, a new parking structure, and more.

A request for proposals (RFP) was issued in fall 2022.
