CLEVELAND (Business Wire) -- Cliffs Natural Resources Inc. (NYSE: CLF) (Paris: CLF) today
announced its inclusion in two of the inaugural Maplecroft Climate
Innovation Indexes (CIIs) launched by Bloomberg in January 2010. The
Maplecroft CIIs, calculated by Bloomberg and based upon evaluations by
country and corporate risk intelligence firm Maplecroft, ranks the
top-performing U.S. companies in terms of climate-related innovation and
carbon management programs. In addition to its listing in the Maplecroft
CII index (Bloomberg: CICOMP), which narrows an initial set of the
approximately 800 largest stocks to the top-performing 300 stocks based
on their engagement in public climate-related programs, Cliffs was also
ranked in the Maplecroft CII Leader (Bloomberg: CII) index as one of the
100 top-performing companies from the Maplecroft CII index.

"We are pleased that Cliffs has been recognized by Maplecroft and
Bloomberg for its efforts in addressing the complex issue of climate
change," said Joseph A. Carrabba, chairman, president and chief
executive officer of Cliffs. "As the Company continues its growth in the
international mining and natural resources industry, we remain committed
to developing fair and sustainable solutions that balance risks to the
environment, our economy, our nation and our world."


The Maplecroft CIIs were compiled through a climate screen of all U.S.
companies ($1 billion or more in market capitalization) against more
than 100 different criteria. Stocks were rated using varied sources,
including Web sites, sustainability reports, investor presentations and
UN Global Compact Communications on Progress, and supported by
third-party stakeholder viewpoints and direct engagement with the
companies. Maplecroft's global risk indices were also used to understand
wider climate change risk exposures across the entire company.
