Frequently Asked Questions
Has Colliers published a sustainability report?
Confidence: High. As of July 2026, Colliers has published a 2025 Global Sustainability Report. The report says it covers environmental, social, and governance priorities and uses GRI (Global Reporting Initiative), SASB (Sustainability Accounting Standards Board), and TCFD (Task Force on Climate-related Financial Disclosures) frameworks, which are common reporting standards for explaining sustainability performance. The company also referred to this as its sixth annual global sustainability report. Consumers can review the report to see the company’s own figures and targets..

What is Colliers' sustainability rating?
Confidence: Low. As of July 2026, no independent sustainability rating from Good On You, B Corp, or Trustpilot was found in the provided material. The available evidence instead comes from Colliers’ own reporting and one independent article noting that its science-based targets were approved in June 2023. That means there is some third-party confirmation of its climate work, but not a broad public rating score in the material here. Consumers who want a fuller external assessment may need to check rating platforms directly..

What sustainability certifications does Colliers have?
Confidence: Moderate. As of July 2026, Colliers says 68% of its offices received environmental or wellbeing certifications, but the specific certificate names are not listed in the material provided. It also said it has helped certify more than 50 buildings and office areas in Hungary through its green advisory work. In addition, its science-based targets were approved in June 2023, which is a formal check by the Science Based Targets initiative, or SBTi, on whether climate goals match climate science. Consumers would need more detail to know exactly which building or office certifications were used..

What is Colliers doing about carbon emissions?
Confidence: High. As of July 2026, Colliers says it has set a science-based target through the Science Based Targets initiative and plans to reach net zero in its own operations by 2030. It also reported a 32.2% reduction in Scope 1 and 2 emissions from a 2021 baseline. Scope 1 means direct emissions from its own activities, while Scope 2 means emissions from purchased electricity and energy. The company also said 42% of its electricity came from renewable sources across its global portfolio..

Is Colliers' packaging sustainable?
Confidence: Low. As of July 2026, packaging is not discussed in the material provided. Colliers appears to be a professional services and real estate company, so its sustainability work in this content focuses on buildings, emissions, reporting, and workplace wellbeing rather than product packaging. There is not enough evidence here to say whether any packaging used by the company is sustainable. Consumers looking for this detail would need to ask Colliers directly..

Is Colliers ethical in its supply chain and workers?
Confidence: Moderate. As of July 2026, Colliers says its ESG strategy includes diversity, equity, and inclusion, and it also says it wants to improve inclusion across its procurement practices. The company reported that more than 32% of manager-level and above roles were held by women in 2025, which gives some sign of workforce progress. However, the material does not provide detailed public data on supplier audits, labour standards, or worker complaints. That means the picture is partly positive, but not fully transparent..

What is Colliers doing about sustainability overall?
Confidence: High. As of July 2026, Colliers is working on sustainability through a formal ESG strategy, climate targets, reporting, and client services. It has three main focus areas: environment, inclusiveness, and health and wellbeing. It also says it has a net zero goal for its own operations by 2030, has reported lower emissions and more renewable electricity use, and uses GRI, SASB, and TCFD frameworks to report progress. This suggests a structured approach, although much of the detail still comes from the company’s own disclosures..
