an American craft brewery located in Fort Collins, Colorado, is recognized as a brewing industry leader in the promotion of environmental consciousness and sustainability.

New Belgium was opened in 1991 by Jeff Lebesch, an electrical engineer and homebrewer, and Kim Jordan, a social worker. A European bike tour which included stops at Belgian bars and breweries inspired the couple to take their homebrew operation commercial. Upon returning to Colorado, the pair began their business, with Lebesch designing and building equipment to brew beers patterned after those he experienced in Belgium. Jordan took on the business end of the brewery, handling the marketing, selling, package design, and accounting functions. In 1996 New Belgium recruited Rodenbach brewmaster Peter Bouckaert. From those humble beginnings, New Belgium has grown into the third largest American craft brewery in a matter of 18 years, with a current volume of more than 500,000 US barrels.

The New Belgium line of beers is anchored by the flagship pale ale Fat Tire but also features several beers of Belgian derivation as well as a number of innovative style varieties. These include beers such as Sunshine Wheat, Abbey Ale, Trippel, Frambozen, and the wood-conditioned Flemish-style sour red ale La Folie.

New Belgium has also gained well-deserved recognition for its sensitivity to the environmental impact of its brewing operation. New Belgium is a recognized leader in brewing industry sustainability efforts, including attaining 100% of its electricity  from wind power, using evaporative coolers rather than compressors for maintaining building temperatures, recycling Colorado beetle-kill pine trees into interior woodwork, using on-site wastewater treatment, and several other sustainability initiatives.
