The Mediavore's Dilemma: Making Sustainable Media Choices
How Big is the Media's Carbon Footprint?"Veronis Suhler Stevenson, a private equity firm, reported that the media industry rose from the 10th largest sector of the economy in 1975 to the 5th largest in 2009. According to the 2009 Deloitte Media and Entertainment Industry Outlook, media and entertainment is one of the largest sectors in the U.S. economy: About $950 billion was spent on products and services provided by media and entertainment companies in 2006. That spending is expected to grow by 38 percent to $1.3 trillion by 2011.
Another key aspect of the media game that can be measured is advertising spend. A major source of revenue to media companies is the purchase of advertising by brands who spend in excess of $125 billion in the U.S. each year to sponsor media products. Close to $500 billion is spent each year worldwide. According to research firm Kantar Media, while advertising expenditures fell 12.3 percent in 2009 due to the recession, advertising expenditures in the first quarter of 2010 rose 5.1 percent from 2009 to $31.3 billion.
The U.S. Department of Energy reports that approximately 360,000 tons of CO2 equivalent greenhouse gas emissions are associated with each billion dollars of economic activity, which would mean the carbon footprint of the media industry could be as much as 500 million metric tons of greenhouse gas. That would be equivalent to the annual greenhouse gas emissions of 130 coal-fired power plants burning 2.6 million railcars of coal; or the annual greenhouse gas emissions from 95 million four passenger vehicles burning 56 billion gallons of gasoline. The DOE also reported that in 2008 the United States consumed about 138 billion gallons (or 3.3 billion barrels) of gasoline and emitted approximately 6.9 billion metric tons of CO2 equivalent greenhouse gas."
