Energy & Emissions

Our large portfolio of stores, warehouses and food production plants are significant contributors to our energy and carbon impacts. With a large, complex supply chain, we also produce carbon emissions via the products we sell and suppliers we partner with to procure and manufacture these products.

Reducing our climate impacts is a key part of our sustainability commitment. We have a history of reducing carbon emissions intensity through investments in energy efficiency, renewable energy and refrigerant emissions measures. We continue to expand the implementation of existing solutions that have proven successful, as well as identify and evaluate new innovative technologies and collaborations that have the potential to further improve sustainability.

Our 2020 Sustainability Goals reflect current commitments to reduce energy and carbon impacts from our business. In 2020, Kroger established a new science-based greenhouse gas reduction goal for our business to guide our climate impact reduction work into the next decade.

Our Stores

Our stores are focused on increasing energy efficiency and reducing greenhouse gas emissions. New stores are designed with energy efficient features while existing stores are retrofitted with new technologies, so we continue to capture energy savings across our portfolio. We also work to decrease our refrigerant emissions through leak reduction initiatives and investments in lower-carbon refrigerants.

million kWh in potential annual electricity savings

LED retrofits

In 2019, Kroger installed glass doors to cover open refrigerated cases in 250 of our supermarket stores. When fully rolled out, this improvement will save 56 million kWh of electricity and 4 million therms of natural gas annually.

For the third year in a row, Kroger earned the U.S. EPA ENERGY STAR Partner of the Year award. We currently have 821 ENERGY STAR certified stores.

Electricity savings
Electricity savings

By the end of 2019, Kroger had achieved an electricity savings of 47.4% from a 2000 baseline in our supermarket stores. This equates to 2.2 billion kWh electricity that was avoided.

Our Plants

Kroger Manufacturing has built a strong foundation in identifying and implementing energy efficiency improvements in our manufacturing plants. Through regular goal-setting, energy tracking, collaborative leadership and internal benchmarking, our facilities can make progress on reducing energy intensity in our operations.

Anaerobic digester

Our K.B. Specialty Foods plant in Greensburg, Ind., has a wastewater treatment facility that uses anaerobic digestion to process food byproducts into renewable energy for the plant.

In 2019, Kroger’s Manufacturing team broke ground on a new solar installation at our La Habra Bakery in La Habra, California. The 2,900 solar panels will produce enough power to offset 20% of the plant’s electricity consumption.

Continuous improvement

This year, our K.B. Specialty Foods plant also transitioned to an ammonia refrigeration system, which greatly reduces the plant's greenhouse gas emissions and ozone depleting impacts.

Our Warehouses

Our Supply Chain team moves several million items across the country every day. To improve efficiency in our fleet, we replace old vehicles with newer, more efficient ones and invest in truck improvements. We also optimize our driving operations and invest in emerging technologies to test scalability for the future.

Electric trucks

Kroger is investing in electric vehicles in our truck fleet, with 10 Tesla vehicles planned for our California distribution network.

Solar power installations
Solar power installations

Kroger’s largest solar array to date, on the roof its Paramount, Calif., distribution center, became fully operational in 2019. The array can produce 4.28 million kWh of clean power for the facility each year, enough to offset 50% of the building’s electricity needs.

Fleet efficiency
Fleet efficiency

By 2019, Kroger's fleet had improved fleet efficiency by 10.84%, from a 2010 baseline. We attribute these increases to new technologies and increasing efficiencies in how we make deliveries and operate our equipment.

Renewable Energy

Kroger’s energy management strategy includes adopting renewable energy because we recognize the associated potential for reducing our climate impacts. Collectively, Kroger's solar and wind installations generated more than 12.87 million kWh of renewable energy in 2019. We also have two anaerobic digesters that process organic waste and wastewater and produce renewable biogas as a by-product.

Carbon Emissions Trends

Reducing our carbon footprint is an important pillar in Kroger’s sustainability commitment, and we continue to invest in energy efficiency and low-carbon technologies. Kroger has measured and managed our total carbon footprint since 2006. In 2019, our total corporate carbon emissions decreased by 2.83% to 5,749,758 tCO2e, driven by decreases in the consumption of electricity, stationary and mobile fuels. Our normalized emissions also continue to decrease.
