CAA’s guidance also including booking sites to enable passengers to make ‘more informed travel decisions’
Airlines and booking firms should give UK customers information about the environmental impact of their flights, the regulator has said.
The Civil Aviation Authority urged booking sites to enable passengers to make “more informed travel decisions” by setting out estimates for carbon emissions for flights landing or taking off from British airports.
New guidance published by the CAA aims to standardise the kind of data already published by some airlines and websites and to make it available at the time of booking so passengers can make comparisons.
The regulator said it would start monitoring and possibly enforcing the new rules after April 2027.
