Aircraft emissions: The dirty sky
All big ideas start life on the fringes of debate. Very often it takes a
shocking event to move them into the mainstream. Until last year interest in
climate change was espoused mainly by scientists and green lobbyists-and the few
politicians they had badgered into paying attention. But since Hurricane
Katrina, something seems to have changed, particularly in America.
There are plenty of anecdotal signs of change: Britain’s pro business
Tories have turned green; Al Gore is back in fashion in America. Companies are
beginning to take action and encouraging governments to do the same. Europe
already has an emissions trading system (ETS) for its five dirtiest industries.
In America, although the Bush administration still resists federal legislation,
more and more states do not.
So far the political about global warming have centred on two polluters,
smoggy factories and dirty cars. Next month the European Parliament will vote on
whether to extend its emissions trading system to airlines. If it decides in
favor, the whole industry will feel the impact, for it will affect not just
European airlines but all those that fly into and out of the EU. Talk about this
prospect soured the International Air Transport Association’s annual meeting
this week in Paris. But whatever happens in the EU, the airlines look set to
face vociferous demands that they should pay for their emissions.
In some ways, the airlines are an odd target for greens. They produce only
around 3% of the world’s man made carbon emissions. Surface transport, by
contrast, produces 22%. Europe’s merchant ships spew out around a third more
carbon than aircraft do, and nobody is going after them. And unlike cars-potent
symbols of individualism-airlines are public transport, jamming in as many
people as they can into each plane.
What’s more, many air travelers cannot easily switch. Car drivers can hop
on the train or the bus, but transatlantic travelers can’t row from London to
New York. Nor can aircraft fuel be swapped for a green alternative. Car drivers
can buy electro petrol hybrids but aircraft are, for now, stuck with kerosene,
because its energy density makes it the only practical fuel to carry around in
the air.
Yet in other ways, airlines are a fine target. They pay no tax on fuel for
international flights, and therefore escape the "polluter pays" principle even
more niftily than other forms of transport. Their emissions are especially
damaging, too-partly because the nitrogen oxides from jet engine exhausts help
create ozone, a potent greenhouse gas, and partly because the pretty trails that
aircraft leave behind them help make the clouds that can intensify the
greenhouse effect.
Slowly, businessmen and politicians are coming to agree with scientists. If
this generation does not tackle climate change, its descendants will not think
much of it. That means raising costs for all sources of pollution. Even those
deceptively cheap weekend breaks cannot be exempt.
