Green Key's new certification criteria are now in effect. Is your hotel ready to demonstrate its environmental performance? 🌱
Since 1 October 2026, Green Key's revised 2026–2031 criteria have applied to new applicants, with existing certified establishments transitioning by the end of 2027.
For hotel operators, this raises an important question:
Can you demonstrate your environmental performance without spending weeks gathering utility bills, spreadsheets and operational records?
Certification readiness goes beyond having sustainability policies in place. It also means maintaining reliable evidence of how resources are consumed and how improvements are managed.
That starts with five practical steps:
→ Measure water and energy consumption consistently.
→ Compare performance against occupancy and operational activity.
→ Identify unusual consumption patterns.
→ Document corrective actions.
→ Verify results and maintain reliable records.
At Noytrall, we believe sustainability data should serve two purposes: **improving day-to-day operations and supporting credible environmental reporting.**
Continuous monitoring cannot replace the certification process, but it can make resource management and evidence collection considerably more systematic.
We've explored what the revised Green Key framework means for hotels and how operators can start preparing today.
