COLLIERS PUBLISHES 2024 GLOBAL SUSTAINABILITY REPORT

Colliers International Group Inc. has released its 2024 global sustainability report, highlighting the firm's achievements and progress against targets established in 2021. The report also offers a first look at Colliers's refreshed sustainability strategy, Built to Last, which is based on an updated materiality assessment conducted in the first quarter of 2025. The strategy is designed to align Colliers's priorities with today's most pressing environmental, social and governance challenges and opportunities, anchored around three core pillars:

• Environmental sustainability -- supporting decarbonization and climate resilience;
• Workplace experience -- creating inclusive, healthy, high-performing spaces;
• Ethical governance and practices -- embedding trust, transparency and responsible innovation.

"As a global provider of real estate, engineering and investment management services, we are in a unique position to help owner, investor and occupier clients realize their sustainability aspirations while driving the same positive impact for our own operations," said Jay Hennick, global chairman and chief executive officer of Colliers. "I'm proud of our 2024 performance and remaining agile in our approach to what's next. I look forward to continuing our journey toward a more sustainable future though Built to Last."

Highlights from the 2024 report include:

• Achieved a 27.6-per-cent reduction in Scope 1 and Scope 2 emissions per square foot from the company's 2021 baseline;
• Earned Well Health-Safety Ratings in 87.4 per cent of Colliers offices greater than or equal to 2,500 square feet, up from 35 per cent in 2022;
• Expanded the company's electric vehicle fleet to more than 170, representing an increase of five times in just two years;
• Reached 88-per-cent participation in the company's global employee engagement survey, with scores exceeding external benchmarks;
• Sixty-eight per cent of the company's Colliers Gives volunteering goal achieved.

To support the next phase of the company's sustainability leadership, Tonya Lagrasta has been appointed global head of sustainability at Colliers. A long-time sustainability leader and trusted adviser within the Colliers business, Ms. Lagrasta brings more than 20 years of experience across sectors, including commercial real estate, retail, consumer goods, financial services, pharmaceuticals and the public sector. In this role, she will spearhead the implementation of Built to Last and drive integration of sustainability across Colliers.

"Sustainability is a reflection of our values in action and a pathway to long-term resilience," said Ms. Lagrasta. "Built to Last reflects where we are today -- and, more importantly, where we're going. I'm energized by our people's passion and proud to help lead this next chapter of impact."
