United States Supermarket Scorecard 2024

The 2024 edition of the biennial Climate-Friendly Supermarkets Scorecard marks the third time in four years that EIA scored the biggest U.S. supermarket chains on their actions to reduce emissions of climate super pollutant hydrofluorocarbons (HFCs). Each company is scored on actions in three categories of technology adoption, refrigerant management, and policy & commitments. For more information, visit our scorecard FAQ page. 

Regarding technology adoption, this refers to a company’s installation of refrigeration systems that use ultra-low global warming potential (<10 GWP) refrigerants. Medium-GWP refrigerants are those with potentials from 150-1400 GWP, and high-GWP are any refrigerant above.

Sector Progress

There has been an increase in commitments to tackle refrigerant emissions by U.S. supermarket retailers, but we aren’t yet seeing the implementation, or specifics about implementation plans, to meet those goals in terms of wide adoption of climate-friendly ultra-low global warming potential (<10 GWP) refrigerants across stores. For example, Walmart has made a major commitment to eliminate all emissions including HFCs by 2040, but has only installed ultra-low GWP refrigerants in a single store and released no specifics on its implementation plans or anticipated milestones. EIA hopes to see companies such as ALDI and Walmart with leading HFC commitments develop and publicly share more detailed plans for meeting these targets including interim progress dates.

Of the sixteen companies evaluated, only three –ALDI, Target, and Whole Foods– received passing scores. Nine companies have increased their scores from 2022, but some of these improvements were incremental. Meanwhile, seven companies saw decreases in scores and one maintained its prior score. 

In comparing overall scores from 2022 and 2024, the ‘policy and commitments’ category has seen the largest increase. This category reflects company commitments to adopt ultra-low GWP refrigerants in store equipment, to decrease refrigerant emissions, and engagement with policy and industry stakeholders on the issue of HFCs and refrigeration. Twelve of the sixteen companies have a public commitment to reduce refrigerant emissions, however only eight have a time-bound goal for reducing HFCs.

There was a notable decrease in the category of refrigerant management across stores, which assesses public disclosure of company average leak rates and efforts to reduce refrigerant leaks. Meijer continues to lead this category by achieving a 6.5% annual leak rate showing that best practices for leak reduction can lead to drastic emission reductions below the EPA estimated 25% average for the sector as a whole.

Emissions from U.S. supermarket refrigerant leaks are estimated to equal 65 billion pounds of coal burned in a year. Addressing these leaks is crucial to curbing emissions, and several companies showed progress on efforts to reduce refrigerant leak rates, although only five of the companies disclose an annual average leak rate. 

The increasing goals and commitments by leading companies are encouraging, but are still falling far short of what is needed to stem the contribution of avoidable super pollutants to the climate crisis. EIA urges citizens, investors, and supermarket companies to call for and implement actions toward a complete phase-out of these gases globally.

Call to Action

Given the significant global warming impact of HFCs, EIA is calling for all supermarkets to: 

  1. Develop a strategy to fully phase out all HFCs in stores by 2035, including an interim target to reduce HFC emissions by 50% by 2030.  

  2. Immediately use only HFC-free refrigeration in all new builds and major retrofits.

  3. Use only recycled and reclaimed refrigerants to service existing equipment that uses HFCs.

  4. Reduce corporate average refrigerant leak rate to EPA GreenChill best in class rate of <5% and publish progress towards this goal.

  5. Implement upgrades to leak monitoring and repair best practices, including a zero-leak tolerance policy which requires leaks to be repaired prior to adding more refrigerant.

  6. Make public commitments or goals to reduce HFC use and emissions and proactively engage with stakeholders in industry and policy settings.       

  7. Reduce the overall climate footprint of their cooling including through energy efficiency measures and easy-but-impactful steps like adding doors or night shades to open cases, upgrading to LED lighting, and reducing leaks.

  8. Enhance transparency by regularly publishing information quantifying current refrigerant emissions, all actions taken to adopt technology, reduce leaks, increase efficiency, as well as stating measurable future commitments to reduce use and emissions.
