The climate case for aluminium
The climate issue is heavy. Aluminium is light

The temperature is rising. The polar ice is melting at an increasing rate. Al Gore, the UN’s climate panel and an increasing number of environmentalists and experts have given the world a waking call. Our climate problems are man-made. People are worried and are demanding measures that can reverse this development. People want action and they want it now!

But not many of us are prepared to give up all the things that make life enjoyable. And we cannot, in good conscience, deny others access to the same benefits we have enjoyed in full for many years. That’s why the number of cars in the world will continue to multiply. Living standards will increase for more and more people, so will energy consumption.

The climate equation is complex and demanding. It may seem insoluble. Still, we want to contribute in the hunt for solutions. By bringing in the aluminium factor.

The most important advantages of this very relevant light metal are found in its properties; the challenges lie in its energy content.

The production of primary aluminium is energy intensive. Once produced, however, aluminium becomes a bank of energy – in solid form. The deposit is paid back in the form of lower energy consumption in vehicles, as discovered by the car and transportation industries. In their search for lighter solutions, they use more and more aluminium. The same is the case in packaging and construction. Recycling of this light metal is another payback area, requiring a minimum of energy. These are some of the reasons why aluminium is a favored material in a life cycle perspective.

For an ordinary passenger car a 100 kg weight reduction alone can reduce fuel consumption by 0.35 liters for every 100 kilometers traveled. Over the lifetime of the vehicle, this represents a two tonne reduction in carbon dioxide emissions.

In the goods transport sector the climate effect is great when the weight of both the vehicle and its load are reduced – by lighter packaging for example. Several of the world’s major goods vehicle producers number among Hydro’s customers. One of them is Brødrene Plagborg of Denmark. They supply advanced, customized goods vehicle extensions using our specially developed aluminium profiles. Thus they enable Scania, Iveco, Mercedes-Benz, Volvo and their customers, among them Post Denmark, to make transport lighter for your benefit and mine.

Some times the answer can be easy.
