Who: The UK Civil Aviation Authority (CAA)
Where: United Kingdom
When: 5 February 2026
Law stated as at: 16 April 2026
What happened:
The CAA has published a new framework setting out guidance and principles on the provision of standardised consumer environmental information in the aviation sector. The framework applies to airlines and other organisations selling or advertising applicable flights – those departing from or arriving at UK airports. It also extends to package holidays that include such flights.
The CAA expects airlines and other relevant organisations to take adequate steps towards implementing the framework by 30 April 2027 and intends to review airline websites and booking platforms during 2027 to monitor uptake.

Why this matters
Airlines and other organisations selling or advertising flights departing from or arriving at UK airports will want to be looking to begin assessing their current environmental information disclosures against the framework’s principles and methodologies.
The CAA has signalled that it intends to move to a mandatory approach if adequate steps towards implementation are not taken. Organisations should therefore treat the framework as a practical benchmark of best practice for compliance readiness, and consider what operational and technical changes may be required to publish standardised emissions data at the point of booking before 30 April 2027.
