We are committed to eliminating water waste from brewing through world-class efficiency, and to safeguarding shared water resources in high-risk areas.

Water is essential to our products and for cleaning during brewing. But in a changing climate, drought will become more widespread, reducing the quality and availability of water. That’s why we are investing in the latest technologies to maximise efficiency in our breweries and to increase the availability of fresh water for the local communities whose resources we share.

  • Partner to safeguard shared water resources in high-risk areas
  • 25% reduction in water usage at our breweries
  • Explore going below 2.0 HL/HL at all high-risk breweries

Our approach towards ZERO

Our aim is to eliminate water waste in brewing. That means maximising efficiency, and treating and reusing wastewater wherever possible. In 2019, we achieved a 12% reduction in water consumption per hl production from 2015. Building on this will require further investment, innovation and working in partnership.  

A key task of the Carlsberg Young Scientists Community is to help us address the water challenge. We partner with organisations in high-risk areas, using innovative technology to improve availability of fresh water for the local communities whose resources we share.

Supporting global goals

As a global brewer with operations in high-risk areas, we have a responsibility to ensure both the success of our business and the well-being of the communities around our breweries.

Our targets for ZERO water waste contribute to SDG 6: Clean water and sanitation. We address targets SDG 6.4 and 6.5 – increasing water use efficiency and implementing integrated water resource management. Our community engagement plans show our commitment to partnership and SDG 17.

Partnering Towards ZERO water waste

Halving water usage at Fredericia brewery

Developing a sustainable tomorrow can only happen in partnership. The ambitious project at our Fredericia brewery in Denmark is the result of a public-private partnership, DRIP, which works to improve water efficiency across our industry. State-of-the-art technology water recycling technology will allow us to safely reuse 90% of process water.
