Global Brewer Rated in the Top 10 Among Beverage Companies for Sustainability
Practices

DENVER and MONTREAL, June 10 /PRNewswire-FirstCall/ -- Molson Coors Brewing
Company (NYSE: TAP) has been ranked eighth overall and second in the alcohol
beverages category by The Pacific Sustainability Index (PSI) in an analysis of
the voluntary environmental and social reporting of companies on the Fortune
Global 500 and Fortune 500 Consumer Food, Food Production and Beverages sector
lists. The PSI ranking system, developed by the Roberts Environmental Center
of Claremont McKenna College, recognized Molson Coors for company-wide
commitment to sustainability and dedication to establishing a corporate
personality that fosters equality and diversity.

PSI analysts credit Molson Coors with providing thorough and valuable
information through the company Web site that demonstrates a commitment to
superior environmental and social sustainability. According to the report,
"The company leaders have expressed their concern for the health of the
environment and their desire to ensure that the practices at Molson Coors do
not cause excessive environmental harm. Additionally, the company considers
responsible social practices, which weigh heavily on equality and diversity,
as essential features of their corporate image."

The PSI analyzes intent, reporting and performance by evaluating companies'
relevant Web pages using two systematic questionnaires. Questions are selected
according to the most frequently mentioned topics in more than 900 corporate
sustainability reports.

In addition to recognition by PSI, in May 2009 Molson Coors received an AA
ranking from RiskMetrics, a leading provider of risk management and corporate
governance products and services to financial market participants. The
increased rating, which improved from the previous rating of an A, was based
on:
-- Improved strategic governance around corporate responsibility
-- Identifying and setting strategic priorities around energy and water
conservation, and reporting detailed annual performance data for the
company's global operations
-- Launch of corporate responsibility section to Molson Coors Web site
-- Endorsement of the United Nations CEO Water Mandate

-- Strong diversity initiatives in employee attraction and retention
programs, including a supplier diversity program in the US

The RiskMetrics rating scale ranges from AAA, the highest rating indicating
the least amount of risk based upon environmental and social performance, to
CCC, indicating the lowest rating and highest risk factors. Molson Coors is
again positioned as an industry leader, rated in the top 10 out of 40 beverage
companies. The average score for the beverage category is BBB.

"This recent recognition by Roberts Environmental Center of Claremont McKenna
College and RiskMetrics demonstrates that we're taking seriously our
commitment to review, report and continually improve our corporate
responsibility performance," said Bart Alexander, vice president, global
alcohol policy and corporate responsibility for Molson Coors. "Our
responsibility commitment is part of our heritage, and today is integral to
our business driving value for our stakeholders including investors."
