(CNN) -- The world of Formula One may seem an unlikely source of inspiration for a major carbon-cutting initiative, but technology used for coordinating pit-stops is primed to slash emissions from airports across the globe.
According to Britain's National Air Traffic Services (NATS), more than half the planes landing at London's Heathrow airport are stuck in circles overhead -- often for 20 minutes at a time -- as they wait for its congested runways to clear.
NATS says the carbon cost of this pile-up in the sky is an estimated 600 tons a day.
And this is where McLaren, the hugely successful Formula One team behind former world champions Lewis Hamilton and Jenson Button, have come in with an unexpected solution.
Over the years the company has developed modeling software to analyze live racing data and visualize a range of potential scenarios -- allowing pit crews to make strategic decisions in the blink of an eye -- all in an effort to get their cars back out onto the racetrack milliseconds ahead of their competitors.
It's this ground-level tracking technology that could hold the key to unlocking congestion, reducing CO2 emissions by streamlining the way aircraft make their own pit-stops once they've landed -- dropping off passengers, refueling and departing again with F1 efficiency.
This similarity between a motor race and an airport runway was first observed by Peter Tomlinson, head of aviation data solutions at NATS, while attending a workshop on cross-industry collaboration at McLaren's UK technology center three years ago.
"It became clear that the pit-stop in a race track, with cars coming in, changing tyres and refueling and going out again actually is pretty similar to an aircraft arriving at the airport, parking at the gate, passengers getting off, refueling and going out," said the air traffic veteran, who has over 30 years experience in the industry.
