Sustainability at GRESB

As a global membership organization with operations across leased offices, GRESB maintains zero Scope 1 and 2 emissions as the company does not own or exert operational control of building energy systems (our office energy consumption is included in our Scope 3 emissions). Similarly, GRESB does not operate any corporate vehicle fleets. While this business model minimizes our direct environmental impact, we recognize our responsibility to engage collaboratively with building operators and suppliers to measure our office energy consumption, advocate for improved building efficiency, and support alignment with Paris Agreement goals. Our Amsterdam headquarters operates on 100% renewable energy, demonstrating our commitment to sustainable operations where possible within our operational framework.

GRESB’s products and services are hosted on cloud-based servers and we actively measure the Scope 3 emissions generated by this operational model as we serve our global members. We are establishing robust policies and practices to measure, mitigate, and limit these emissions whenever possible, working closely with our cloud service providers to understand and reduce the environmental impact of our digital infrastructure while maintaining the high-quality service delivery our members expect.

As an organization with a global reach, a significant portion of GRESB’s emissions stems from essential work-related travel. We are actively calculating our business travel emissions (Scope 3) and developing comprehensive policies that prioritize low-carbon transport options, including favoring train travel over flights whenever feasible for regional journeys. While we encourage virtual meetings as the first option, we recognize the need for in-person engagement with our members and are committed to making our business travel as sustainable as possible.

For daily commuting, we encourage GRESB employees to favor lower-carbon options such as biking and public transport, providing free public transport access to all employees. We are continuously working to improve our measurement and mitigation of work-related travel emissions through enhanced tracking systems and evolving travel policies that balance operational needs with our environmental commitments.

GRESB implements a comprehensive approach to sustainable procurement and waste management to minimize our environmental footprint. We prioritize local suppliers across our operations, from food and beverage services to office supplies, and purchase in bulk using reusable crates to eliminate single-use plastic packaging. Our daily catering services feature vegetarian and plant-based menu options to reduce our food-related emissions, with red meat being entirely removed from our menu offerings.

To support responsible waste disposal, we encourage proper waste triage in our offices with appropriate disposal signage and are actively collaborating with building managers and other tenants to introduce composting as an additional waste stream. Our waste management strategy emphasizes reduction, reuse, and recycling to divert waste from landfills whenever possible. We also educate and encourage employees to engage in responsible waste disposal practices in their home offices while promoting digital-first work practices to minimize paper consumption and printing.

GRESB believes that sustainability and social impact are collective responsibilities integral to our organizational culture. All members of the GRESB team hold each other accountable for nurturing and maintaining both an eco-friendly work environment and an engaged community presence. Beyond our environmental stewardship, we encourage and support team members’ involvement in their communities through personal interests and GRESB-sponsored initiatives. All team members receive paid time off for volunteering annually, and we organize quarterly volunteering activities that allow the GRESB team to bond while giving back to their local communities. Examples include our Earth Day cleanup initiative in 2025—volunteering with a local social enterprise to remove plastic waste from Amsterdam’s canals.

GRESB is dedicated to fostering an inclusive culture, reflective of the diverse global audience that we serve. Over 50 nationalities have joined GRESB since the company’s inception. Our Human Capital policy champions equity and personal growth, guiding us in cultivating an inclusive environment through diverse, skills-based hiring practices and continuous opportunities for career development. To uphold a safe working environment and thriving workplace culture, GRESB has a comprehensive Code of Conduct available to all employees, as well as an appointed and trained internal confidential counselor to support employees with workplace issues.
