Cliffs Natural Resources Inc. (NYSE: CLF) (Paris: CLF) today announced the publication of its first Sustainable Development Report, which provides an overview of the environmental, social and economic impacts of the Company’s operations, as well as goals for further implementation of sustainable and socially responsible practices across all aspects of its business.

Written in accordance with the Global Reporting Initiative (GRI) Sustainability Reporting Guidelines, the Report aims to establish baselines within several key sustainability areas, including:

• Governance, Management and Transparency
• Environmental Stewardship
• Promoting Sustainable Development in Local Communities
• Economic Impact
• Respecting Employees

Through a continuous process of measuring performance, setting targets and programs, Cliffs aims to act as an agent of positive change in its communities.

“With our substantial growth in recent years, Cliffs is now of a size and scale that requires us to expand our focus beyond an excellent safety record, and we must place similar importance on other core sustainability values, such as health and wellness, environmental protection and economic impact,” said Joseph Carrabba, chairman, president and CEO of Cliffs. “That is the intent of this first report, to share the current state of the company, both where we have historically performed well, and where we have some opportunities for improvement.”
