The claim
The Celtic Collection, the hotel group that includes the Celtic Manor Resort, announced in June 2026 that it had achieved ISO 14001 certification across all its hotels and the International Convention Centre Wales. The announcement describes ISO 14001 as an independently audited system and describes A Cube TIC as the accrediting body. It also mentions the group’s earlier Green Dragon Level 4 standard and a commitment to net zero by 2050.
For anyone shortlisting ICC Wales, the question is what that certificate actually tells you.
What ISO 14001 is
ISO says ISO 14001 sets out the criteria for an environmental management system and is the only standard in its ISO 14000 family that an organisation can be certified to. The edition ISO currently lists is ISO 14001:2026, and ISO’s 2024 survey counted more than 670,000 certifications worldwide.
In practice, certification is evidence that an organisation has a system for identifying its environmental impacts, setting objectives, controlling its operations and improving over time, and that an external auditor has checked that system. It is a meaningful signal of governance. What it does not do, by itself, is tell you the carbon footprint of your room hire, how much of the food from your dinner will be wasted, or whether the organisation’s targets are ambitious.
Other claims you will meet
Venues and agencies cite a range of schemes and targets, and they are not interchangeable:
- Company-wide certifications. The Business Design Centre and DRPG both describe themselves as B Corp certified. That is a different scheme with a different scope from an environmental management system.
- Ratings. C2events reports a Silver medal from EcoVadis and says it tracks and benchmarks event carbon emissions through its own programme.
- Targets. Liverpool Experience Campus states an ambition of net zero by 2030; the Business Design Centre says it has a plan to reach net zero before 2030; the Celtic Collection commits to 2050. A target date is a commitment, not a result, and the boundary of what is counted can differ.
Turning a claim into a brief
- Ask for the certificate itself: its scope, the sites covered, the certification body and the expiry date.
- Ask what data the venue can give you for your event, such as energy use, waste by stream and catering information, and how each is measured.
- Separate targets from achieved results in anything you publish about the event.
- Remember what the venue does not control. Delegate travel, freight and your own suppliers sit outside a venue’s management system, and are often where an organiser has the most influence.
Our view
An ISO 14001 certificate is worth having on the shortlist evidence, and ICC Wales’s makes it easier to ask for the data behind its claims. Treat it as the start of the sustainability conversation, not the end of it. For the ICC Wales space itself, see our desk assessment of the Main Hall and the ICC Wales profile.
