Green Key and Green Care Professional empower businesses to measure and certify their environmental impact

At Green Key, we know that every step toward sustainability matters - and we’re proud to work alongside partners who turn commitment into measurable action. That’s why we’re highlighting the Green Care Performance Calculator from Werner & Mertz Professional, a trusted Green Key partner. 

With the Green Care Performance Calculator, businesses can quantify their resource savings - specifically CO₂ emissions, crude oil, and plastic - achieved by switching to Green Care Professional products. The tool offers more than just numbers: it provides a certified, transparent foundation for sustainability claims, helping Green Key-certified establishments clearly demonstrate their commitment to environmental responsibility. 

The tool produces a personalised certificate, complete with the user’s company logo, showcasing the verified environmental savings. This document is not only ideal for internal sustainability reporting but also enhances external communication - for example, in public tenders or green procurement processes that prioritise verified sustainable practices. 

The latest version of the calculator includes two new indicators: the recyclate content of the container and the recyclate content of the entire packaging (including caps). These additions reflect a deeper commitment to the circular economy, aligning with Green Key’s own sustainability criteria. 

“Our goal is to best prepare companies for the transition to a genuine circular economy,” says Thomas Ulbricht, Head of Werner & Mertz Professional. “With the Green Care Performance Calculator, we’re turning our sustainable product design into a competitive advantage - especially in the face of evolving regulatory landscapes.” 

This shared vision aligns perfectly with Green Key’s mission to support accommodations and businesses that want to make credible, responsible choices for people and planet. The calculator’s methodology has been independently validated by INTECHNICA GmbH, ensuring a robust and reliable foundation for its results. 

We encourage all Green Key-certified businesses - and those aspiring to certification - to explore the benefits of this tool. Use it to make your sustainability journey visible, back your actions with certified data, and strengthen your environmental credentials.

Statement on Green Key's status - 2025 and beyond

The current Green Key standard (criteria and explanatory notes) took effect on 1 January 2022 and has been internationally recognised. This Green Key standard is expected to remain in force until 31 December 2026.

The certification process includes third-party verification, conducted either by an independent auditor or a National Jury, to ensure compliance with Green Key requirements.

To meet upcoming EU directives on consumer protection and green claims, Green Key is committed to securing scheme approval from Denmark’s national accreditation body (NAB), a member of the International Accreditation Forum.

During 2025, Green Key will be updating and revising criteria and process to allow for application for scheme approval which will be submitted by 31 December 2025, with the goal of achieving approval by 31 December 2026.

Any updates to the Green Key standard and certification procedures resulting from this process will be implemented no later than 1 January 2027.

To achieve certification, establishments must demonstrate their commitment to sustainable practices and undergo periodic audits to ensure continuous improvement.

In addition to offering certification, Green Key actively supports its members by providing guidance on sustainable management practices and helping businesses adapt to new environmental challenges. By fostering a culture of sustainability, Green Key-certified establishments not only reduce their ecological impact but also appeal to a growing market of eco-conscious travellers.

Green Key is more than just a certification programme; it is actively involved in various global initiatives and projects aimed at furthering sustainable tourism. Green Key collaborates with UN Tourism (World Tourism Organization), and other international bodies to promote best practices in the industry. Green Key also participates in education and outreach campaigns to raise awareness among both tourists and businesses about the importance of sustainability.

Green Key’s vision for the future involves continuously evolving its standards to address new sustainability challenges, such as carbon reduction, plastic pollution, and biodiversity preservation.

Hyatt Hotels Corporation establishes Green Key as a preferred partner in Asia Pacific

A new cooperation between Green Key and Hyatt Hotels Corporation has been signed, specifying Green Key as a preferred sustainability certification programme for the hotels in Asia Pacific.  

Yakitori Bar, Hyatt

Hyatt Hotels Corporation, headquartered in Chicago, is a leading global hospitality company guided by its purpose – to care for people so they can be their best. As of March 31, 2024, the Company’s portfolio had more than 1,300 hotels and all-inclusive properties globally, including over 280 properties in Asia Pacific.

As the world evolves and new challenges emerge, Hyatt has advanced its global Environmental, Social and Governance (ESG) strategy through World of Care to care for the planet, people and responsible business. The global approach is derived by closely listening to what is most important to colleagues, guests, customers, hotel owners, investors and the communities in which Hyatt hotels operate around the world.

From reducing food waste to the eliminating use of single-used plastic, Hyatt teams across Asia Pacific are accelerating efforts toward Hyatt’s 2030 environmental goals – focused on areas of climate change and water conservation, waste and circularity, responsible sourcing and thriving destinations. Learn more at: https://about.hyatt.com/en/world-of-care.html

Andrew Mensforth, Senior Vice President Operations in Asia Pacific, said:

‘Aligning with World of Care, our global approach to advancing care for the planet, people and responsible business, we are pleased to collaborate with Green Key as we continue our ongoing efforts to cultivate sustainability knowledge across our hotels in the region’.

‘It is great to see an important hotel chain like Hyatt recognising the sustainability and educational value of partnering with Green Key, and choosing as a preferred certification programme partner. We are really looking forward to seeing more of Hyatt’s hotels in Asia Pacific adopting the Green Key criteria and validating their sustainability efforts against the certificate’.
