Environmental impact of flights ‘should be reflected in ticket prices’

A call is being made for flight ‘eco-labelling’ and the impact of airlines on the environment to be reflected in ticket prices.

Reduced baggage allowances would also reduce aircraft emissions, according to the author of a new report which calls on airlines to eliminate needless emissions and enable consumers to make informed choices about how to travel.

The International Institute for Environment and Development (IIED), in association with the International Centre for Responsible Tourism, says the industry has a “collective responsibility” for reducing emissions.

The report, commissioned from the Carbon Consultancy and launched to mark World Travel Market’s World Responsible Tourism Day today (Wednesday), highlights avoidable greenhouse-gas emissions and recommends ways to reduce the sector’s contribution to climate change quickly and easily.

It calls for real and standardised reporting of airline emissions and eco-labelling of flights.

Report author Hugo Kimber, of the Carbon Consultancy, said: “Our analysis shows that it should be possible for government, consumers and business to make some short-term impacts on emissions reduction via eco-labelling, information delivery and to start reflecting the environmental cost in ticket prices.”

One quick fix would be to reduce the baggage allowance, according to the report. A five-kilogram reduction in baggage allowance on the main short haul route from London to Spain would reduce carbon dioxide emissions by 54,400 to 68,000 tonnes – the higher value equating to 2,950 flights from London to Malaga.

The report calls for emissions from aviation to be included in the European carbon-trading system with an interim efficiency-based eco-tax to reflect the cost of carbon. It urges European governments to adopt the proposed Single European Sky – a regional air traffic control system that would eliminate the annual 12 million tonnes of needless carbon dioxide emissions created by national systems.

And airport expansion should only take place if demand for flying is still rising after passengers and airlines start to bear its environmental cost in line with recommendations already made to the UK government.

“The statistics surrounding aviation emissions are confusing for consumers because they are based upon a wide variety of source material,” said Kimber. “Even individual flight emissions calculations can vary by as much as 300% for the same flight depending on the methods used.”

Standard fuel-use reporting by airlines would allow the creation of a flight-labelling scheme, the report claims. This would help consumers to choose routes and airlines that emit less, and which in turn would encourage airlines to adopt more efficient technology and aircraft deployment.

More than 20% of aviation capacity flies empty, indirect flights can emit up to 29% more carbon dioxide than direct ones, and that the use of aircraft by individual airlines can make a big difference to emissions.

But passengers are left in the dark about these figures and so can’t exercise consumer power to reduce emissions, the report claims.

Kimber said: “The environmental impact of aviation is often considered in relation to global emissions, but consumers want to know what the impact of their flight choice will be using standard reporting guidelines.

“It is important to enable flight purchasing based upon efficiency but you can’t do that without labelling, and for that you need to know how much fuel each airline/aircraft uses in relation to passengers and cargo.

“Flying produces considerable global benefits, especially for developing countries but at an environmental cost which it must be assessed against by consumers and policymakers.”

Dilys Roe, senior researcher at IIED who commissioned the study, added: “Aviation brings benefits to governments, the public, business and the airlines themselves but nobody is covering the environmental costs.”

She pointed out that air travel is extremely important to the economies of poor countries, both in terms of bringing tourist revenue and exporting fresh produce, so it is key that emission reduction policies do not harm the poor.

“Cutting emissions from aviation is everyone’s responsibility and in everyone’s interests – make it your responsibility too,” said Harold Goodwin of the International Centre for Responsible Tourism at Leeds Metropolitan University. “This report show sensible ways to do this in a way that does not harm those who have contributed least to the problem and will suffer most from its impacts.”
