Why calculate the footprint of your brewery / beer?


A carbon footprint can help you to:


-  Identify cost savings;

-  Enhance your brand by demonstrating environmental and corporate social responsibility;

-  Make more sustainable decisions by testing how different variables (e.g. packaging types,    distribution method or distance) impact on the overall footprint;

-  Compare your performance to industry averages; and

-  Align your commercial and environmental goals.


CWC's carbon footprint calculator


We have developed a carbon footprint calculator for breweries who want to understand the impact of their products and own operations. This calculator is a simple and cost-effective solution because it is tailored specifically to the brewing sector. You can read more about it on the SIBA website:



What do I need to supply for a carbon footprint assessment?


1. Decide what you want to measure (just brewery emissions, the whole life of bottled beer?)

2. Provide quantities of inputs (e.g. malt, hops, electricity for brewing) and outputs (e.g. spent grain, beer). Also provide either fuel use data or average distance travelled for distribution.

3. Provide other information, such as where the inputs are sourced from, and how they are transported to your brewery.


What will CWC do?


CWC will then calculate the inputs and outputs per hectolitre of beer (or per year depending on whether we are calculating brewery emissions or product emissions), and input this data into the carbon calculator. The calculator multiplies the inputs, outputs and travel data by specific emission factors, to give a total carbon footprint per product or per year. CWC will then analyse the findings.


CWC assessed the carbon footprint of The Kernel Brewery's Pale Ale. You can read more about the project here.


CWC has also assessed the carbon footprint of a beer produced in a Williams Warn Brew Keg.
