Denver AND Montreal (March 25, 2009) "“ Molson Coors Brewing Company (NYSE: TAP; TSX), today announced for the second consecutive year, its facilities around the world will turn off all non-essential lights on Saturday, March 28, from 8:30 "“ 9:30 p.m. local time, in observance of Earth Hour.

Earth Hour, created by the World Wildlife Fund (WWF), is a global climate change initiative that calls on individuals and businesses around the world to join together in the simple act of turning off their lights for one hour to express their dedication to action on climate change. This worldwide effort began two years ago in Sydney, Australia when more than two million people turned off their lights for an hour and reduced the city's energy consumption by more than 10 percent. It became a global movement in 2008 with more than 50 million people participating and this year, more than 500 cities and 75 countries have confirmed participation.

In the US, the Molson Coors' Denver headquarters and MillerCoors offices and breweries will switch off all non-essential interior and exterior lights in observance of Earth Hour. In Canada, the Molson breweries will turn off all exterior lighting and signage, while UK-based Coors Brewers Ltd. will turn off exterior lighting not needed for safety purposes. During Earth Hour last year, Toronto-based Molson reduced its kilowatt consumption by approximately 1,544 KWH, conserving enough energy to power a house for a month.

"The success of this event for Molson Coors is about more than turning the lights off for one hour, it is about changing the way we think about energy and challenging ourselves to do things differently," said Bart Alexander, vice president, global alcohol policy and corporate responsibility for Molson Coors. "That's why we look forward to participating again this year and we are also encouraging our employees to observe Earth Hour at home to learn more about reducing their energy consumption."

Molson Coors' commitment to energy conservation and reduced carbon emissions is not limited to Earth Hour "“ it is also exemplified in its corporate policies and business objectives, which include the company's global target to reduce its energy use, indexed to production, by 4 percent annually.

In recognition of its efforts, Molson Coors recently received the highest ranking among brewers and alcohol companies, the 2nd highest ranking in the beverage industry category and ranked 12th in overall climate change strategies in the 2009 annual CERES report. In 2008, The Carbon Disclosure Project awarded Molson Coors a score of 90 percent and ranked the brewer 4th in its Retail & Consumer Sector category.

Additionally, Coors Brewers Ltd. eliminated more than 300,000 distribution miles through a series of conservation initiatives. The results saved the equivalent of 33,000 gallons of fuel. In the U.S., MillerCoors is setting emissions goals with the Environmental Protection Agency Climate Leaders Program by the end of 2009.
