Air travel emissions are proving difficult and costly to cut, but travellers can make a surprisingly big difference simply by changing how they travel to and from the airport.

For many of us, especially in Australia, flying is an essential form of transport, so how can we reduce its environmental impact? Getting to and from the airport is an overlooked aspect of air travel that offers an immediate way to cut total carbon emissions from the trip by a surprisingly large amount.

Our newly published research shows for an average economy passenger flying from Sydney to Melbourne, the carbon emissions from using a fossil-fuelled car to get to and from the airports make up a staggering 13.5% of the total door-to-door emissions.

Our research shows it’s easily achievable if travellers can be persuaded to change how they get to and from the airport.

Two recent studies at the University of California, Davis, suggest showing consumers the emission outcomes of different gate-to-gate flight choices, such as aircraft types and transit stops, can prompt them to choose greener flights, reducing emissions by up to 3.8%. But air journeys don’t start or end at airports.

Our air-travel carbon emissions are divided into ground and air segments and counted as airport and airline emissions respectively.

      Thanks, I appreciate that.

      But yeah, one of the things I actually quite like about Lemmy so far is that because it’s a bit quieter, the chances that you can contribute meaningfully to a thread a day late are still pretty good.
