"Our climate is changing, and airlines are under pressure to reduce emissions
from air travel. 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. At a global scale, this number reaches 12.1% for
long-haul flights and up to 22.8% for short-haul air journeys.
For comparison, in the International Air Transport Association’s 2050 net-zero
emission roadmap, 13% of global airline decarbonisation will come from electric
and hydrogen propulsion. A further 65% is to come from mass adoption of
sustainable aviation fuel. This is fuel produced from non-petroleum-based
renewable sources such as some municipal solid waste, woody biomass, fats,
greases and oils.
Each of these big lifters requires a mammoth level of investment and
technological breakthroughs, and comes with limitations and risks. Some
solutions might make air travel prohibitively expensive. Airlines are moving
mountains to decarbonise, but there are increasing concerns their net-zero
plans might not stack up.
In contrast, a 13.5% emission reduction on a Sydney-Melbourne door-to-door
journey today may sound like a dream. Yet our research shows it’s easily
achievable if travellers can be persuaded to change how they get to and from
the airport."
I sometimes take the regular bus to and from the airport. It takes about an
hour because of all the stops on the way, but you can’t beat the price. And the
most effective way to get to and from Narita airport in Tokyo is via train.
