The 2018-year results included combined in-scope Walmart Retail Link data sales collected in January 2019 (sales data from January 1st 2018 through December 31st 2018) and submitted formulation data from in-scope suppliers to the WERCSmart system as of Oct. 21, 2019. The percent of UPC volume weight disclosure in both the baseline year and year of measurement remained materially the same.
2. Walmart suppliers are encouraged to verify purity of ingredients where Contaminants of Concern may exist. From among Walmart Priority Chemicals, Walmart stores and Sam’s Clubs in the U.S. have identified a subset of Sourcing Action List chemicals (SALs). These chemicals will be measured separately from Walmart’s 10% Walmart Priority Chemical Reduction Goal in our Consumables Chemical Footprint.
From among Walmart Priority Chemicals, Walmart and EDF have identified a subset of Sourcing Action List chemicals (SALs), which are petroleum-based chemicals that have been identified because of the potential presence of contaminants of concerns, as indicated by regulatory and authoritative bodies. Suppliers can verify their SALs do not contain any Priority Chemicals when UL’s WERCSmart system measurement enhancements are available.
Suppliers will be able to provide verification information when entering formulation data into UL’s updated WERCSmart system. Walmart will track both verified and unverified SALs by weight volume, number of UPCs, and number of suppliers. Verified SALs metrics will be included in the upcoming report. This data will be available for the 2020 measurements.
3. High Priority Chemicals
We no longer report on HPCs, as they are now included within the comprehensive list of Walmart Priority Chemicals.
