• Managed by Forum Ethibel, this index recognizes the leading European companies in the areas of environment, human rights, community impact, business behavior, human resources and corporate governance.

March 30, 2015 - Abengoa (MCE: ABG.B/P SM /NASDAQ: ABGB), the international company that applies innovative technology solutions for sustainability in the energy and environment sectors, has been included for the third consecutive time in the Ethibel Sustainability Index (ESI) Excellence Europe, created by Forum Ethibel, an independent, non-profit Belgian organization founded in 1992 by various NGOs.

Forum Ethibel launched the ESI Excellence Europe and ESI Excellence Global indices in collaboration with Vigeo, the European ratings agency. Vigeo specializes in preparing ESG (environmental, social and governance) ratings and profiles that evaluate companies based on their environmental and social performance and their corporate governance, as well as providing product and service audits and certifications. Abengoa is currently part of the ESI Excellence Europe index, which it first joined in 2014 and which includes some of the leading companies in terms of ESG.

The decision to include Abengoa in the Ethibel Sustainability Index (ESI) Excellence Europe was based on various criteria, such as the environment, human rights, community impact, business behavior, human resources and corporate governance.

Abengoa has also been recognized by other indices, such as the Carbon Disclosure Project and the FTSE4Good index, joining both in 2008, and it has been part of the Nasdaq OMX Green Economy index since 2012.

Abengoa's inclusion in the ESI Excellence Europe, which is reviewed twice-yearly, consolidates its position as one of the global leaders in developing policies for environmental management, climate change, the management of social employment responsibility, human rights and good governance. It is also further recognition by the market of the company's work, which is greatly appreciated by investors.
