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).

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.

I started to run because I felt desperately unfit. But the biggest pay-off for me was – and still is – the deep relaxation that I achieve by taking exercise. It tires me out but I find that it does calm me down. When I started running seven years ago, I could manage only 400 meters before I had to stop. Breathless and aching, I walked the next quarter of a mile, alternating these two activities for a couple of kilometers.
When I started to jog I never dreamt of running in a marathon, but a few years later I realized that if I trained for it, the London Marathon, one of the biggest British sporting events, would be within my reach. My story shows that an unfit 39-year-old, as I was when I started running, who had taken no serious exercise for twenty years, can do the marathon – and that this is a sport in which women can beat men. But is it crazy to do it? Does it make sense to run in the expectation of becoming healthier?
My advice is: if you are under forty, healthy and feel well, you can begin as I did by jogging gently until you are out of breath, then walking, and alternating the two for about three kilometers. Build up the jogging in stages until you can do the whole distance comfortably.
