The aviation industry has seen huge growth since its beginning. Today, more than two billion people enjoy the social and economical benefits of flight each year. The ability to fly conveniently and efficiently between nations has been a catalyst for the global economy and has shrunk cultural barriers like no other transport sector. But this progress comes at a cost.
In 2008, the commercial aviation industry produced 677 million tones of carbon dioxide (CO2 ). This is around 2% of the total man-made CO2 emissions of more than 34 billion tones. While this amount is smaller compared with other industry sectors, such as power generation and ground transport, these industries have viable alternative energy sources currently available. For example, the power generation industry can look to wind, hydro, nuclear and solar technologies to make electricity without producing much CO2 . Cars and buses can run on hybrid, flexible fuel engines or electricity.
-powered trains can replace
locomotives.
The aviation industry has identified the development of biofuels as one of the major ways it can reduce its greenhouse gas emissions. Biofuels provide aviation with the capability to partially, and perhaps one day fully, replace carbon-intensive petroleum fuels. They will, over time, enable the industry to reduce its carbon footprint significantly.

Sustainable flight
TAM was the first airline in South America to carry out an experimental flight using biofuel on November 22, 2010. Produced from the oil of 100% domestic nettlespurge, known in Portuguese as pinhão-manso, it reduces carbon emissions by between 65% and 80% compared with petroleum-derived kerosene, according to research. Besides, the plant does not threatens the food chain, as it is not edible for humans nor animals. “Compared with other biofuels, the fuel from this plant is very promising for the Brazilian scenario,” says Paulus Figueiredo, TAM’s fuel manager. The next step in the project is to implement a farming unit, in reduced scale, at TAM’s Technological Center in São Carlos (SP), exclusively to conduct studies and make better cultivation techniques viable. “The objective is to carry out studies concerning technical and economic viability to build a biofuel Brazilian platform based on nettlespurge,” explains TAM’s CEO, Líbano Barroso. The experimental flight was a joint effort between TAM, Airbus, CFM International (joint venture between U.S.’s GE and the French Safran Group) and Air BP. The trip was authorized by Brazil’s National Civil Aviation Agency (ANAC) and by the European Aviation Safety Agency (EASA).

Aedo e adivinho têm em comum um mesmo dom de “vidência”, privilégio que tiveram de pagar pelo preço dos seus olhos. Cegos para a luz, eles veem o invisível. O deus que os inspira mostra-lhes, em uma espécie de revelação, as realidades que escapam ao olhar humano. Sua visão particular age sobre as partes do tempo inacessíveis às criaturas mortais: o que aconteceu outrora, o que ainda não é
(Jean-Pierre Vernant. Mito e pensamento entre os gregos, 1990. Adaptado.)
(...) o elemento religioso não limitou os seus efeitos ao fortalecimento, no mundo da cavalaria, do espírito de corpo; exerceu também uma ação poderosa sobre a lei moral do grupo. Antes de o futuro cavaleiro receber a sua espada, no altar, era-lhe exigido um juramento, que especificava as suas obrigações.
(Marc Bloch. A sociedade feudal, 1987.)
