Our position
We do not turn hoteliers into sustainability experts.
We bring the expertise, establish the baseline, identify the opportunities and deliver measurable improvements.
Since 2014, Green Partner has helped hospitality businesses control costs, improve operational performance, meet regulatory requirements and build credible sustainability credentials.
Founded in the Netherlands within the hospitality industry, we specialise in certification, energy efficiency, circular economy, zero waste, ESG and CSR, with practical, straightforward solutions that improve efficiency and reduce costs.
Our expertise in hotels and our thorough verification of supply chains have taken us into other industries, and into the design of certification schemes for scheme owners and certification bodies. Hospitality remains our core business.
Who leads us
Andrés von Fellenberg van der Molen
Hotelier | Sustainability Expert | Lead Auditor | Certification Scheme Architect | Public Speaker
Above all, Andrés is a proud hotelier, with nearly 30 years of international hospitality experience and a passion for continuous improvement, resource optimisation, sport and horses.
With extensive knowledge of European legislation and sustainability compliance, he is an experienced Lead Auditor appointed by accredited conformity assessment bodies, a certification criteria developer, framework architect and author of certification programmes. He is also an international speaker on hospitality, sustainability and European regulatory compliance.
In 2014, convinced that the hotel industry needed a fundamental change in its approach to sustainability, he founded Green Partner in the Netherlands. Built on the philosophy of hoteliers working for hoteliers, the company specialises in sustainability management, certification, energy efficiency, circular economy, zero waste, CSR and ESG.
His philosophy is simple: turn sustainability into a measurable competitive advantage through operational efficiency, regulatory compliance and financially sound improvements — with a hotelier’s no-nonsense approach. Practical, results-driven and straight to the point.
