Hoteliers working for hoteliers · Since 2014
Hotel business with a sustainability twist.
Your hotel is a business, not a charitable institution or a non-profit organisation. Your hotel has to be profitable, comply with the law and keep owners and investors satisfied. We make sustainability work for you, without adding pressure on you or your team, by finding the balance between profitability and responsibility.
No romance. No fairy tales. No nonsense.

We are Green Partner
Do what you do best. Let us do our job.
You were trained to run hotels, not to become an expert in carbon accounting, raw-material recovery, energy efficiency or EU legislation.
We are hoteliers. We understand the business, and we understand you: budgets, payroll, demanding guests, owners and investors. Since 2014 we have been taking sustainability off your desk and turning it into savings, compliance and a reputation that holds up.

Our specialist expertise
We do not just implement certification schemes. We write them.
Scheme owners, certification bodies and industry organisations rely on us for criteria, governance and conformity assessment. The hotels we advise get the same rigour.
The Criteria Makers
From an initial scheme concept to an auditable certification framework, with defined responsibilities, evidence requirements and conformity assessment procedures, aligned as applicable with:
- ISO/IEC 17065
- ISO/IEC 17021
- ISO 19011
Internal audits and certification audits are always kept separate, to protect impartiality. We prepare you for certification; independent certification bodies certify.
Work with us your way
You decide how involved we become.
From a single conversation to complete outsourced management. Our involvement adapts to your team’s capacity and your business objectives.
- Just advise me — I need an expert opinion.
- Show me the way — my team will implement.
- Work with us — we deliver it together.
- Do it for us — you manage the project.
- Keep us on track — periodic internal audits.
- Manage our sustainability — ongoing support.
Insights
Know what applies to your hotel before it applies.
- Microplastics in Hotel Cosmetics and Amenities: A Hidden Contradiction to Responsible HospitalityRefill dispensers do not make your amenities plastic-free. Guests can scan the label in seconds, and they will believe the app before they believe your supplier.
EU rules, in plain words
New directives, filtered for hotels.
We follow new European directives, laws and regulations and tell you what applies to your hotel, and what to do about it.
The Green Partner promise
Less pressure. Less stress. Better controls. Stronger margins. Credible claims.
We measure our work by improvements in your business, not by the number of reports we produce.
