Gottfried Härle runs the first carbon-neutral brewery in Germany. At first, people laughed at him. But now, visitors from around the world come to the town of Leutkirch to get a closer look at how he produces such tasty beer without releasing harmful emissions. Härle was honored with the German Sustainability Prize in 2010. The recipe is simple: boilers are heated using special woodchips that are made in the brewery. That innovative heating process saves about 120,000 liters of fuel oil – or 350 tons of CO2 – a year. A film by Vanessa Fischer.
