In New Zealand, the Facebook group Fly-less Kiwis was formed to focus attention on the need to reduce air travel. Unlike some campaigns, which encourage people to stop flying completely, either for a year or forever, its aim is simply to spread awareness of this issue and to support its members’ decisions to eliminate unnecessary flying.
Aviation accounts for up to 8% of global greenhouse gas emissions. (Other sources put the figure lower, at 2-3%, but this refers to only the direct CO2 emissions, not the total climate impact due to water vapour, nitrous oxides, contrails, and aerosols.) Aviation is growing extremely quickly, up 75% in 8 years:
and is projected to rise by 200-360% by 2050:
So far, few countries have any measures in place to rein in the growth of aviation. Some flights incur a carbon price (for example, domestic flights in New Zealand and internal flights in the EU). The UK departure charge is partly carbon based – £78 for a long-haul flight. This really is a global issue: New Zealand’s aviation emissions, at 0.8 tonnes CO2/person, are not so different from those of other developed countries.
(To be clear, while aviation is important, it’s not one of the top issues in climate change mitigation, which remain (both in New Zealand and globally) electricity generation, land transport, and economy-wide carbon pricing.)
Paul Callister, a founder of Fly-less Kiwis, writes:
Many of us on this group probably grew up not doing much flying. We used other means if traveling within NZ and even overseas. Then in our midlife we may well have done quite a bit through our work and for leisure. Now we are pulling back or stopping for climate change reasons. But when I mention this issue to many younger people (in hopefully a casual way not a preaching tone) I sense a moment of horror. The middle class amongst them grew up with hyper-mobility. Their first school trip may have been to Vietnam rather than Auckland. They have been to Sydney or the islands half a dozen times and may have been an exchange student in Europe. Even the environmentally committed, who are leading social media campaigns and/or going to protests, cannot easily see a life without flying or reduced flying. So if one looks at a ‘lifetime emissions’ profile, many of us used up our share in midlife, while these young people have already used theirs up. It’s going to be a real challenge for them.
I think we can almost categorise air travel into three broad groups:
1. Vital (air ambulances, disaster relief etc).
2. Important (visiting overseas relatives, going to the occasional overseas scientific conference).
3. Trivial (I would suggest that weddings in Rarotonga, flying all the guests in, would count as that). So you do not worry about the vital group. You work hard to minimise the impact of the important category. And you put in place a whole heap of disincentives for the trivial travel.
One year has made a huge difference in the amount of attention given to aviation and climate change. Let’s make 2020 the year in which awareness turns into action.
