Water is a critical natural resource. Post is committed to taking action to reduce overall water consumption and effectively manage wastewater discharge to protect the health of local watersheds. To be a responsible company, our efforts related to water stewardship must be aligned with providing high quality and safe products to our consumers. We also realize that not all water is equal, so we are committed to assessing our water impact, particularly in high water stress environments.
Post supports UN Sustainable Development Goal (SDG) 6 and ensuring the availability and sustainable management of water and sanitation for all. We all play a role, across the world, to work together in addressing shared water challenges including water quantity, water quality, water governance, important water-related ecosystems, water, sanitation and hygiene (WASH), and resiliency to extreme weather events.

Post is committed to evaluating our water impacts, particularly in high water stress environments.
Weetabix is committed to reducing water consumption by 20% by 2025 (2015 baseline).
Post currently has owned and operated production sites and warehouses and distribution centers in North America and the United Kingdom. Post maintains a global water risk assessment to determine sites located in regions of potentially high water stress using the following data sources:
- World Resources Institute (WRI) Aqueduct Water Risk Atlas
- WWF Water Risk Filter
- FEMA National Risk Index
Based upon our assessment, Post has identified the following breakdown of sites by water stress level projected to 2030:
Water Stress Level | Production Sites | Warehouse & Distribution Sites |
---|---|---|
High | 3% | 3% |
Medium | 23% | 6% |
Low | 74% | 91% |
Water Stress Locations 2030 Projection |
Approximately 5.5% of water use is in regions of high water stress. The results of our assessment, combined with our water and wastewater data, is used to inform decisions on further assessment, actions, and investments.
Compared to our fiscal year 2020 baseline, Post has had a 13.5% increase in total water use but a 1.5% decrease in water use intensity. Currently, 54% of our water is sourced from third-party providers and 46% is from groundwater by volume. Our wastewater discharge volume for fiscal year 2022 was 1,769 million gallons.

Post also completed a baseline screening of approximately 2,300 global ingredient and packaging supplier locations to evaluate sourcing from regions of potentially high water stress using the following data sources:
Based upon the assessment, Post has identified the following breakdown of supplier locations by water stress level:
Water Stress Level | Current Supplier Locations | Current Supplier Locations – 2030 Stress Projection |
---|---|---|
Very High | 0% | 6% |
High | 13% | 10% |
Medium | 10% | 10% |
Low | 23% | 22% |
Very Low | 54% | 52% |
