Naturally, there is a strong correlation between energy consumption and carbon footprint, carbon dioxide being generated when fuel is burned. So any measures to conserve energy will have a direct impact on the carbon footprint bottom line: turning off lights; energy conservation protocols in all operations; not forgetting to get employees to think about the most efficient way they can get to work.4

And then there is waste. Most brewers divert their spent grains to cattle feed—quickly, otherwise they sour, much to the distaste of the cows. Surplus yeast can be used to feed pigs—the porkers being especially delighted as there is usually plenty of alcohol still bathing the cells. Spent water is increasingly diverted by brewers to anaerobic digesters, where bacteria convert the molecules in the water to methane, which can be burned with the release of utilizable energy. Some brewers put waste water onto fields, to grow crops such as canola that can be converted into biodiesel to fuel trucks. Some are debating channeling gases from landfill to burners. More than one has installed vast solar panel arrays; one I know is aiming to erect a wind turbine.
