in 2012, according to Air Transport Action Group and this number is sure to grow as global demand for flight continues to skyrocket.
"Aviation will double in size worldwide in the next two decades, and if we’ re not able to provide a sustainable means to fly, we will create a ceiling for growth in the industry," says Ignaas Caryn, director of innovation at KLM Royal Dutch Airlines.
As a result, it looks like the aviation industry being ready to green up its game. In January, Boeing announced a new initiative to build a biofuel supply chain in the United Arab Emirates, as well as research it’s conducting into biofuels made from salt water-consuming desert plants.
To name just a few partnerships, the airplane manufacturer teamed with Virgin Australia Airlines is to produce sustainable aviation fuels from special trees in Australia. Airbus has also joined other aerospace companies in launching the ITASCA initiative, a collaborative project funded by the European Union to produce and test the use of sustainable jet fuel.
Frederic Eychenne, Airbus’ head of new energies, notes that no single crop will do the job for biofuels, and that to achieve true sustainability, biofuel—like food—is best when it’ s locally-sourced.
"Different countries grow different crops. They have different refineries in place. Sustainability isn’ t just about reducing emissions in the air. We have to consider the whole life-cycle in terms of production," he notes.
The main barrier to use biofuel on a larger scale, says Caryn, is the price. "Today, bio jet fuel is still three to four times more expensive than fossil fuel, because there’ s no continuous production. There’ s a demonstrated hole in the value chain," he notes.
To solve the problem, in 2010 KLM became a joint founder of SkyNRG—a major supplier of eco-efficient jet fuel.
"We believed the development of bio jet fuel was important, and that we couldn’t keep it within the boundaries of KLM, so we decided to come up with a new company. In the last five years, SkyNRG have supplied approximately 25 airlines," he says.
SkyNRG is also working with airlines and airports around the world to create bioports—or supply chains of sustainable jet fuel—in a bid to ultimately bring down the price.
"With an increase volume, we could see price parity within the next ten years," says Caryn.
According to Frederic Eychenne how to achieve true sustainability?
选项
A、Using crops to produce fuel.
B、Using trees to produce fuel.
C、Using local resources to produce fuel.
D、Reducing emissions in the air.
答案
C
解析
细节题。根据题干中的Frederic Eycherme可以定位到文中第五段中的Frederic Eychenne,Airbus’head of new energies,notes that no single crop will do thejob for biofuels,and that to achieve true sustainability,biofuel一like food—is best when it’s locally-sourced,从这里可以看出他认为最好的办法就是用当地产的植物.所以C项最符合文章意思。因此,正确答案是C。
