If you've ever booked a hotel because its website promised 'carbon-neutral stays' or flashed a leafy eco-badge, the rules just changed in your favour. The EU's Empowering Consumers for the Green Transition Directive — EmpCo for short — came into effect on Sunday, and it targets exactly the kind of vague sustainability marketing that's become everywhere in travel.

The law bans generic green buzzwords with nothing behind them, outlaws 'carbon-neutral' claims that rest purely on buying offsets, and requires companies to have real plans in place if they advertise future climate goals. Sustainability labels — including the eco-certifications hotels love to display — now need to be backed by a relevant certification verified by a third party, or set up by a public authority. Comparison tools fall under the rules too.

One detail worth knowing: the protection follows the consumer, not the company. A hotel chain or booking platform headquartered outside the EU is still covered if it sells to European travellers. So this isn't just a Brussels box-ticking exercise — it reshapes how the global hospitality industry talks about its green credentials.

Hotel industry sustainability leaders have largely welcomed the change, arguing it brings much-needed transparency and consistency to a space that's been a free-for-all. Expect some casualties, though: smaller or weaker eco-labels that can't meet the third-party verification bar may simply disappear from hotel websites and booking engines.

For travellers, the practical upshot is simpler decision-making. Claims like 'eco-friendly' or 'climate-conscious' with no substance behind them should start vanishing from listings. What remains should be labels you can actually check — certifications with a verification body behind them, or schemes run by public authorities. If a property still claims to be carbon-neutral, it now needs more than an offset receipt to say so.

It's worth staying a little sceptical anyway while enforcement finds its feet. Look for named certifications you recognise, check what the label actually covers (a hotel might be efficient with water but have no policy on food waste, for example), and treat a site's own sustainability page as marketing until it points to something verifiable. Still, for anyone who's ever paid a premium for a 'green' stay and wondered whether it meant anything, this law is a step towards the answer being yes.
