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. It said the carbon emission data should reflect factors such as aircraft type and fuel use, and take into account the type of seat occupied. It added that this information was already available in sectors such as rail, and a standard framework would help aviation’s ambitions to become net zero for carbon emissions by 2050. The CAA director, Tim Johnson, said: “Airlines providing understandable and comparable emissions data will enable passengers to make more informed travel decisions.
