Energy & Carbon 

Energy & Carbon

We recognize the link between how much energy we use and how much carbon we emit into the atmosphere, and we are making significant strides in reducing our energy consumption and carbon footprint.

We assess the carbon footprint of our entire value chain, including greenhouse gas (GHG) emissions from our breweries, as well as emissions from upstream activities such as growing barley and hops, malting and sugar processing, and downstream activities such as the manufacturing of our packaging, distribution to retailers, and recycling or disposal of empty bottles and cans at end of life. 

By 2025, we aim to reduce absolute carbon emissions from our direct operations by 50%, and achieve an absolute carbon emissions reduction of 20% across our supply chain. As part of our plan to reduce carbon emissions and energy usage in our operations, we are committed to investing in renewable energy solutions and performance tracking technology to support greater accountability and visibility in our operations.


MillerCoors annually reports to the Walmart Sustainability Index

We share our progress relative to water use intensity, greenhouse gas emissions, sustainable packaging as well as several elements from our Brewing Materials operations - all things related to working with barley growers and sourcing our great ingredients. In November 2017, MillerCoors joined the inaugural year of Walmart’s Project Gigaton; an initiative to reduce emissions in the global value chain by 1 billion metric tons – a gigaton – by 2030.

Our commitment builds upon our joint Fertilizer Optimization Plan with them. In April 2018, Walmart recognized the organizations that meaningfully contributed to this ambitious goal. We are proud to support this global commitment through our work in Sustainable Agriculture. To learn more please visit:

Energy Performance

In 2017, MillerCoors consumed 104 mega joules (MJ) of energy per hectoliter (hl) of beer brewed, a 2.6 percent reduction from 2016. Our breweries have made significant strides to increase energy efficiency in the past year.

We reduced GHG emissions by 31.7 percent since 2013—a 7.6 percent decrease from 2016. We will continue to look for ways to decrease our energy consumption to reduce our value chain carbon footprint per barrel of beer.

From moving to renewable energy sources to finding methods to optimize energy use, our breweries have taken action and made energy reduction a priority.

Solar Array Installation in Irwindale

In 2015, the Irwindale Brewery went live with a 3.2 megawatt direct current solar photovoltaic array.  Installed across more than 10 acres of brewery land, the 10,620 solar PV panels generate enough electricity to brew more than 7 million cases of beer annually. This is the largest solar PV array installed at any U.S. brewery.

Transition from Coal-fired to Natural Gas Boilers

Converting our breweries from coal-fired to natural gas boilers played a major role in the reduction of our carbon footprint in 2015. Our Albany, Trenton and Golden Breweries have all completed the conversion to natural gas boilers and are in the final stages of consuming residual coal inventories. We reduced our total emissions by approximately 91,333 MT CO2e by switching from coal to natural gas.
