Tenerife Officials at Edinburgh Airport are looking at plans to reduce the cost of on-site parking to cut down on the number of passengers being dropped off and picked up.
These so-called "kiss and fly" passengers make up a quarter of journeys to the airport and bosses want to cut this number to help reduce pollution created by traffic.
Airport officials are currently assessing the best way to do this and to get passengers using public transport or their own cars.
This includes constructing safer car parks around the terminals and reducing the overall cost of airport parking, as well creating new bus routes to connect the airport to Edinburgh city centre.
It is understood that a taxi sharing service is also being considered, which would see passengers returning from destinations such as Palma, Malaga and Tenerife being grouped together for their journey home.
Airport managing director Richard Jeffrey said: "The biggest cause of local air pollution around the airport is not from aircraft but from road traffic travelling to and from the airport."
However, Mr Jeffrey added that great strides had already been made over the last five years to increase the number of people using public transport to travel to Edinburgh.
