Sustainable conference venues in the Netherlands — what certification really means

The venue brochure was impressive. Six sustainability certification logos, a paragraph about their commitment to the environment, a photograph of the solar panels on the roof. The event manager was convinced.

Until she asked about the CO₂ footprint of the building itself. "We don't have that data centrally available," said the venue manager. "But we offset through tree planting."

That is not the same as being sustainable. But it looks the same.

The certifications in common use

Green Globe is the most widely used international certification for tourism and hospitality. The standard encompasses more than 380 criteria covering sustainability, social welfare, cultural heritage and economics. Venues are audited annually. Reliable as an indication of a serious commitment to sustainability.

Greenkey is aimed specifically at the hospitality and accommodation sector, with participating venues in more than 60 countries. More rigorous than most national quality marks. It is being extended with a dedicated events certificate.

ISO 14001 is a generic environmental management standard that indicates an organisation systematically manages its environmental impact. It says nothing about the absolute impact — only that a management system is in place.

Breeam and LEED are building certifications that assess the energy performance and sustainability of the building itself. Relevant for venues investing in new construction or renovation.

Greenbookings' sustainability score translates venue data into a concrete score based on measurable criteria, including the volume of CO₂ saved through linked tree-planting initiatives.

What the certifications do not tell you

No commonly used certification for event venues measures or offsets the travel emissions of attendees. This is the most significant blind spot: a venue can be 100% green while travel emissions account for 70% of the event's total footprint.

Certifications also do not measure how sustainable the catering supply chain is, how far suppliers travel to make deliveries, or how much food waste remains after an event.

What to ask when choosing a venue

Concrete questions that go beyond the brochure: - Can you share the building's energy consumption figures for the past year? - What percentage of your energy supply comes from renewable sources? - What is your policy on food waste in catering operations? - Do you have data on the CO₂ impact of a typical event held at your venue? - What measures do you take to encourage visitors to travel sustainably?

Venues that cannot answer these questions may not yet be far enough along in their sustainability journey to substantiate the claim.

Venues that take it seriously

There are venues in the Benelux that go well beyond certifications: actively collaborating with caterers on short supply chains, rewarding attendees for travelling by public transport, and measuring and publishing their full CO₂ footprint.

Greenbookings identifies these venues through its sustainability score — based not on certifications alone, but on measurable criteria applied consistently across every venue.

The conclusion

Certifications are indicators, not guarantees. A venue with five logos on its website can be less sustainable than one without a single certification that takes concrete measures and reports transparently.

The question that matters: can this venue tell me what the measured environmental impact of an event with them actually is? If the answer is "no", the logos are decorative.

The event manager learned this the hard way. She booked the certified venue. After the event, she requested a CO₂ report for her own CSR reporting. "That doesn't exist," said the venue manager. "You're welcome to cite our certificate number in your report."

She didn't.
