The airline industry is 0% emission CO2
By Amandine AMBREGNI

VANCOUVER (AFP) - The airline industry announced this week in Vancouver (Canada) its intention to be "greener" by presenting a target of "0% CO2 emissions" which, however, arouses some skepticism.
"I do not have the answers, but I am sure that research can find solutions to reach this 0% within 50 years. It is realistic," said the boss of the Air Transport Association (IATA) , Giovanni Bisignani at the assembly held in Vancouver.

For him, respect for the environment is the new priority for the sector now that it has returned to profits (5 billion dollars expected in 2007), after several years of losses.

But skepticism has spread in the corridors of the general assembly on this goal of "0%", against the backdrop of rapidly expanding air traffic.

"With the prospect of continuously growing air traffic, between tourism for aging populations in OECD countries, emerging markets and business travel linked to globalization, we have enough to have a cold sweat", acknowledged New York University (NYU) researcher Michael Levine.

The sector aims by 2020 to reduce fuel consumption by 25% via existing means such as optimizing the use of engines in flight and on the ground. However, the annual contribution of global civil aviation to global CO2 emissions will drop from 2%, or 500 million tonnes, to 3% at the same time.

Going to 0%, "that does not make sense", according to Mr. Levine, nor for the boss of Malaysian Airlines Idris Jala, who "does not believe in it from a technological point of view".

IATA is betting on scientific advances, on the efforts of carriers and on public authorities - governments, regulators, United Nations - to impose international standards, or even create a market for CO2 emissions for the sector.

“Achieving 0% CO2 emissions means having a carbon-free fuel, that is to say a hydrogen engine,” explains Trung Ngo, communications director for the Canadian aircraft manufacturer Bombardier.

"The hydrogen engine, that of rockets and which requires huge tanks, has already been tested in the 80s. It is technically viable, but the problem still unresolved to this day is storage, it needs a larger compression of hydrogen ".

As for bio-fuels, which will not reach "0%" of CO2, the problem remains: "fields the size of Florida would be needed to cover 10% of the needs of American carriers", recognizes Philippe Rochat, at the head of the Environment division of IATA.

Hence the urgency of funding research, according to the latter, which advocates investments both public and private.

At present, "the solutions are intermediate", explains Mr. Ngo: the engine manufacturers are working on alternative systems, more economical than the current "turbo fan" type engine.

"The most successful technology is that of + geared fan +, developed by Pratt and Whitney", according to this trained engineer. "It promises an efficiency of 30 to 40% higher than current engines", but is not yet on the market.

On the aircraft side, composite materials make it possible to lighten the weight of airplanes, improve their resistance in the air and therefore reduce fuel consumption.

According to IATA, "an airplane today consumes an average of 3,5 liters per 100km per passenger, which is equivalent to the consumption of a compact vehicle, but with a transport speed six times higher".

The future Boeing 787, which claims to be the most economical on the market and incorporates many composite materials, should lower this average consumption under 3 liters.

Hello
I don't have the answers, but I'm sure research can find solutions to reach 0% within 50 years. It's realistic, ”said the boss of the Air Transport Association (IATA), Giovanni Bisignani at the meeting in Vancouver.


there is no need to do big studies or big research on the way that consumes it in 50 years there will be no more oil, the problem will be solved.
if we survive the shit we do ...

For the G8, the total estimated emissions reach 30000 tonnes of CO2, a good part of which is related to air travel: Bush comes with 2 planes + escort of fighter planes + multitude of helicopters etc ... large sedans in abundance + construction of the protective barrier (12 kms) ... of madness.

And all this for what ? to decide that it will "perhaps" be necessary to reduce CO50 emissions by 2% by 2050:

1 - it's pipo, these shows keep growing with bullshit of this style,

2 - they will have exhausted the oil, the worse the warming will have caused so many imbalances that it will no longer be possible to move freely due to CO2 emissions or worse, that the planet will be difficult to live in and there will no longer be any question of G8, but simply survival.

As for air travel in general, it is difficult to see how we can manage to emit 0% CO2 unless using airships.

OUAIP, in 50 years, it will be too late

It is indeed necessary to use hydrogen, it is the only solution

or streamlined airships like Targol say, it has its charm.

when I was little I had elastic or catapult engine planes ...... :D
I also had a bicycle ....
when i was older i had a sailboat .... :D

joking aside, they must find and they will have the development budgets if they do not want to have to close shop: their luck is that they should not develop devices at 15000 euros.

There are solar planes that are under research and development: http://www.actu-environnement.com/ae/ne ... _2734.php4

It is said that during its use there is no emission of greenhouse gases. However several problems arise: not very autonomous, in the absence of sun it is better not to attempt the flight, the device is huge and can only contain very few people (always the problem of storage).

The plane is a great invention BUT it has caused a lot of nuisance: SOUNDS near airports, transport of viruses or bacteria, mosquitoes etc ... which spread diseases at high speed around the world, influx of tourists in areas superb that have been distorted by tourist parks, etc ........ when CO2 does not speak.

The other day I came across a brochure that explained some simple attitudes to reduce its impact on the environment. Among other things, it was explained that it was better to change my old nasty car that consumes too much and smokes black (a 1.2L without any electric option not even the windows) to buy a nice brand new high-end car (probably a 4x4 3.0L TD since it's fashionable) with air conditioning, computer, DVD and I don't really know what. And I thought about it: it's not just the use of a polluting vehicle. It is necessary to count its manufacture (such equipment made in China with raw materials coming from Russia, assembled in Australia and assembled in a French chain for a car sold in the states), the manufacture of its spare parts (on modern cars 3 / 4 of the repairs is electronic waste), the worn parts that must be treated (throw away or recycling) and finally when this vehicle reaches the end of its life.
It applies to aviation too: even if we managed to fly solar planes, it would not be without impact on the planet. The silicon used to manufacture a solar panel requires very high temperatures, its manufacture is polluting, not to mention the long distances it travels.
Then without petroleum ... everything is petroleum based. Even nuclear. Trying to run a nuclear power station without oil to build it, to manufacture the equipment, to transport the fuel, to take the employees morning & evening ...
In my opinion there is only one solution for the future: reflect on the coherence of the whole. Why we need a plane: tourism, business, freight. (who sees other uses?)

solutions:
- we can survive without visiting the end of the world (living proof: me)
- do we need people who fly 5 hours for a meeting and come back in the evening? (the phone does not date from 1870 ?? then + now there is internet, good ok it also uses current and polluting material but it still has less impact than air travel)
- we must rationalize the flow of goods: no need to go to make clothes (for example) in China, in France we are able to do it. it avoids making long distances, whether by boat or plane

........ more agree with you you will not find !! I drive with a R25 GPLisée from 1989 / 307 km; I'm going on vacation in 000 petrol 504 (1981 km) which has just passed the check this morning valid on the 265st pass. I pushed 000 to 1 km by changing my engine (breakage recovery).

But the system wants that it is necessary to CONSUMER to have this GROWTH which makes the system live, enrich the + rich and impoverish the + poor ..... here, there is ....... I believe that there is a book on the subject to buy somewhere in econology, I saw that this morning.

THE SOLUTION is likely to impose itself even when NATURE will get very angry !!! : Evil: : Evil:
