Advancing sustainable hospitality through responsible cleaning 

How certified plant-based cleaning products contribute to measurable sustainability in the hospitality sector.

As global tourism continues to grow, the hospitality industry faces increasing expectations to reduce its environmental impact. At Green Key, we recognise that sustainability must be integrated into all aspects of hotel operations—including daily cleaning practices. 

While often overlooked, cleaning operations can significantly affect a property's environmental and health performance, from chemical usage and water consumption to indoor air quality. That’s why more hotels are moving toward verified, plant-based cleaning solutions that deliver measurable results.  

As part of our commitment to driving continuous improvement in hospitality, Green Key includes a criterion related to chemical use in daily cleaning. Specifically, we require that at least 75% of all chemical cleaning products used on a daily basis carry a recognised eco-label. This ensures that the majority of products used by certified properties meet strict standards for environmental responsibility, formulation safety, and overall impact. Choosing such products isn’t just about ticking a box—it reflects a broader commitment to responsible operations and transparent sourcing. 

Why responsible cleaning is integral to certification goals 

Properties pursuing or maintaining Green Key certification are expected to demonstrate clear action in areas such as chemical management, resource efficiency, and health and safety. Conventional cleaning products often rely on fossil-derived ingredients, single-use plastic packaging, and synthetic additives—all of which contribute to emissions, waste, and long-term environmental degradation. 

Responsible cleaning offers a practical and impactful path forward: one that aligns with the criteria of Green Key certification while supporting the well-being of staff, guests, and the wider environment. 

 

Certified solutions backed by independent assessment 

Our partner Diversey's SURE™ product range provides an example of a science-based, independently certified solution. These products are: 

  • Plant-based from renewable rescources* and derived from agro-food waste—using materials that would otherwise be discarded. 

  • 100% biodegradable, verified by OECD 301B testing standards. 

  • Free from synthetic dyes and petrochemical ingredients, helping reduce chemical exposure and pollution. 

  • Up to 100% recycled plastic, SURE packaging is made up to 100% Post Consumer Recycled plastic the reduce the amount of virgin plastic and plastic pollution. 

  • Third-party certified, including EU Ecolabel and Cradle to Cradle Certified™ Gold, ensuring transparency and accountability across product lifecycles. 

These certifications are reviewed regularly, providing ongoing assurance of compliance with high environmental and safety standards. 

Supporting the 4 Pillars of net positive hospitality 

Diversey’s  recent innovations aligns with Green Key’s vision of Net Positive Hospitality, where hotels actively contribute to regeneration and community well-being. Responsible cleaning directly supports this ambition by adding value across four key areas: 

  • People 
    Products formulated to achieve the lowest  hazard classifications reduce health risks for cleaning staff and guests. Simplified labelling also aids safe handling and staff training. 

  • Planet 
    The formulations are 100% biodegradable (based on independent assessments) and made from renewable, non-petrochemical sources. They reduce chemical and plastic pollution and help conserve water and energy, contributing to lower emissions and the protection of ecosystems. 

  • Place 
    By embracing circularity and using products certified by Cradle to Cradle™, hotels become stewards of local environmental health. They reduce waste, support regenerative design principles, and can engage with suppliers that share sustainability values. 

  • Prosperity 
    Efficient use of resources, combined with reduced waste and simplified processes, creates long-term operational savings. At the same time, it enhances brand reputation and supports compliance with sustainability standards and customer expectations. 

A practical step toward certification and continuous improvement 

For hotels committed to responsible tourism and high sustainability standards, reviewing and updating cleaning practices is a meaningful step. Adopting third-party certified cleaning products supports Green Key criteria related to chemical use, staff health and safety, waste management, and environmental communication. 

What circular cleaning looks like in practice 

Certified, plant-based products like SURE™ exemplify the principles of circularity—using waste as a resource, minimizing harm, and enabling continuous improvement. They allow hotels to move beyond reducing impact and begin actively contributing to more sustainable outcomes. 

For properties already certified, this represents a clear opportunity to enhance performance. For those beginning their Green Key journey, it is a strong foundation for building credibility and resilience.

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.
