During the “Rio+20 Business day,” Johnny Undeli, head of Hydro’s Bauxite & Alumina business in Brazil, was invited to present aluminium solutions for buildings as an example of how the mining and metals industry to contribute to sustainable development in a low-carbon economy.

“It’s very inspiring to participate in such an important arena, and show how Hydro and aluminium can be part of the solution to our generation’s greatest challenge – the climate challenge,” Undeli said during his presentation.

“We know that buildings represent 40 percent of the world’s energy consumption – nearly twice as much as ships, cars, trains and planes together – it’s obvious that there is a great potential to save energy in buildings. It is important that the industry and the authorities work together on technological solutions that contribute to sustainable growth. Our work on energy-efficient buildings is a good example.”

The Powerhouse concept is a unique partnership of Norwegian companies to create energy-positive buildings that use smart façades in aluminium, renewable energy and other energy-saving techniques. An initial project is under development in Trondheim, Norway. When realized, it will be the northernmost energy-positive building in the world.

Undeli’s presentation at Rio+20 Business was part of Business Action for Sustainable Development 2012, which is a United Nations coordination body for business and industry at Rio+20.

Important participants in the group include the World Business Council for Sustainable Development and the International Council for Mining and Metals. Hydro is a member of both organizations, which are well represented at Rio+20.

The Rio+20 gathering aims to create renewed engagement in sustainable development in a way that meets the needs of today’s population without reducing the opportunities for future generations. The key question addressed there is how to build a “green” economy that is sustainable while lifting millions out of poverty and how international cooperation can be better coordinated.
