With a score of 78 out of 100 points, Hydro ranks as the seventh best on the list and the best in the mining and metals industry.

The survey assessed four important factors of social responsibility:

• Fundamental human rights in society (respect for privacy, individual freedom, prevention of harassment, indigenous peoples' rights);
• Labor rights;
• Absence of discrimination at work;
• Human rights in the production chain.

The survey was conducted by Vigeo Eiris, a global provider of environmental, social and governance research for investors and public and private corporations. The agency assesses the level of integration of sustainability factors in the organizations' strategies and operations and conducts risk analyzes to assist investors and decision makers in companies.

"For years, Hydro's score has been high in the category of sustainable performance of companies by Vigeo Eiris. It is especially gratifying for us to be recognized for the important but challenging work we have done in the area human rights in general and labor rights in particular. At the same time, we are aware that there are still unresolved issues, especially in our production chain, "said Elise Must, leader of Corporate Social Responsibility at Hydro.
