This week, we are in the mountains of Austria with global beer maker Heineken, to meet the team behind the world's first zero carbon brewery.

Reducing the pollution associated with its more than 160 breweries worldwide is a key priority for the business. In fact, by 2020 carbon emissions coming from its beer production will be cut by 40% should it meet internal goals. Michael Dickstein, the company's global director for sustainable development, explains how the impressive project at the Goss brewery in Austria sets the bar for what is to come as the business continues to prove its worth as a responsible company, fit for the 21st century.
