When someone takes a swig from their favorite beer, they may not realize that brewing beer is an energy intensive process. But brewing companies that desire to reduce their carbon emissions are well aware. Carlsberg Group, a global brewer headquartered in Copenhagen, Denmark, has set a lofty goal of powering its breweries with only renewable energy by 2022. Call it the company’s "100 percent renewables by 2022 goal."
The 170 year-old company has a new program called Together Towards Zero, launched this summer. The program is a means to meet its pledge to achieve zero carbon emissions at its breweries by 2030. By that same year, Carlsberg aims to have reduced the carbon footprint of putting a beer in its customers' hands by 30 percent.
