The Sustainable Hospitality Alliance (the Alliance) is delighted to announce a new partnership with GRESB, the global ESG benchmark for real assets, aimed at leading sustainability initiatives within the sector and paving the way for a more sustainable future.

Founded in 2009, GRESB is a mission-driven and industry-led organisation that provides actionable and transparent environmental, social, and governance (ESG) data to financial markets. Comprised of an independent foundation and a benefit corporation, this Netherlands-based organisation and B Corp collects, validates, scores, and independently benchmarks ESG data, offering valuable business intelligence, engagement tools, and regulatory reporting solutions for investors, asset managers, and the wider industry.

The Alliance, consisting of global members, strategic partners, and industry stakeholders, collaboratively addresses critical challenges impacting the planet, people, and places worldwide, with the ultimate goal of reaching Net Positive Hospitality.

Through this partnership, the two organisations will engage in ad-hoc activities such as working groups, events, and training sessions to provide support and leadership to members on their sustainability journey.

Expressing his excitement for the partnership, Glenn Mandziuk, Chief Executive Officer of the Sustainable Hospitality Alliance, said:

“Working collaboratively with the team at GRESB, I am confident that our shared vision will accelerate our sector towards Net Positive through a wide range of initiatives and programmes. The data, insights, and tools held by GRESB will empower our network of members to decarbonise their real estate portfolio using a rigorous methodology and framework.”

GRESB’s ESG assessments are guided by material issues identified by investors and the wider industry. These assessments are aligned with the Sustainable Development Goals, the Paris Climate Agreement, and major international reporting frameworks.

Anna Olink, Director of Real Estate Engagement at GRESB, said:

“We are thrilled to join forces with the Sustainable Hospitality Alliance in our shared commitment to drive the real estate sector towards a sustainable future. Together, through collaborative initiatives and efforts, we look forward to fostering positive change within the industry.”
