Cliffs developed this Sustainability Report in conformance with Global Reporting Initiative's (GRI) comprehensive Sustainability Reporting Framework. Widely used around the world, GRI's framework enables greater organizational transparency by establishing principles and indicators that global organizations can use to measure and report their economic, environmental, and social performance. The Company's Sustainability Report received a third-party assurance and earned a B+ rating for the third consecutive year.

"Responsible and safe operation, respectful engagement and effective environmental stewardship are qualities we seek to both foster and recognize throughout Cliffs," said Kelly Tompkins, Cliffs' executive vice president, legal, government affairs and sustainability and chief legal officer. "Cultivating these qualities creates business value – both the tangible bottom line form of value and significant intangible value in the form of improved relationships, enhanced reputation, new partnerships and collaboration."

Mr. Tompkins added that: "Sustainability allows us to develop new opportunities and mitigate risks, while gaining the support of stakeholders and agencies that allow us to operate and grow."

Cliffs' 2011 Sustainability Report features sustainability accomplishments, such as:

• Cliffs commissioned an independent benchmarking assessment of the Company's environmental, social, economic and governance policies, performance and programs. Cliffs will use this analysis to further identify gaps, prioritize strategic opportunities and discover area for improvement. It will also help identify what information is of most interest to our various stakeholders.
• Cliffs introduced a new Capital Investment System (CIS) to the organization. It is a structured and integrated process designed to assess the economic and technical viability of a capital project throughout all phases of the investment system. The CIS process will integrate enhanced environmental, social, economic and governance considerations in Cliffs' current set of minimum standards to ensure they are effectively addressed in a timely fashion.
• Cliffs voluntarily subjected components of its chromite project in Northern Ontario to an individual Environmental Assessment (EA), the most stringent type of provincial EA process. In addition, Cliffs worked with federal and provincial regulators to develop a coordinated EA review process that integrates requirements of the provincial individual EA and federal comprehensive EA. This will help ensure a consistent EA review process for stakeholders and multiple opportunities for public participation throughout the EA process.
