COLLIERS RELEASES 2025 GLOBAL SUSTAINABILITY REPORT

Colliers International Group Inc. has released its 2025 global sustainability report, demonstrating measurable progress against its sustainability commitments, including reduced emissions intensity, enhanced workplace experience, strengthened governance and ethics, and the responsible adoption of artificial intelligence. The report articulates Colliers's continued advancement of Built to Last, its global sustainability strategy, which focuses on environmental, social and governance priorities that are most critical to managing risk and driving positive impact.

Key highlights include:

• Achieving a 32.2-per-cent reduction in Scope 1 and Scope 2 emissions intensity from its 2021 baseline, representing a 6.4-per-cent year-over-year improvement;
• Sourcing 42 per cent of electricity for Colliers's global portfolio from renewable energy;
• Earning environmental or well-being building certifications in more than 66 per cent of Colliers offices;
• More than 32 per cent of manager-plus roles being held by women.

"As sustainability expectations become more performance driven, our focus is on delivering outcomes that fortify, derisk and create lasting value within our own operations and for our clients," said Tonya Lagrasta, global head of sustainability at Colliers. "I'm proud of our 2025 progress and the way our professionals continue to turn ambition into action. The report reflects where we are today and where we're going as we stay agile, focused and energized about the positive impact we can create together."
