What’s the update?
We’re updating how we assess a product’s water footprint on the environment. The current Water Usage metric is a measure of the total on-farm water required to grow the ingredients in a product. We are now shifting to the Blue Water Usage metric, which is a better measure of a product’s environmental impact on global water resources.
What is Blue Water Usage?
Blue Water Usage is a measure of the amount of blue water (ie. surface and groundwater resources) required to grow the ingredients in a product. The Blue Water Usage metric also takes into account the blue water scarcity in the regions where the ingredients are grown.
Why are we shifting to Blue Water Usage?
While the Water Usage and Blue Water Usage metrics both quantify the amount of water required to produce 1 kilogram of product, Blue Water Usage is more directly related to water resources that are at risk. Because there is increasing global demand for a limited supply of freshwater resources, the conservation of blue water is imperative to maintaining a healthy global water system.
By focusing on global freshwater resources, the Blue Water Usage metric is a more direct indicator of the impact a product has on the water system in its respective regions. Blue water needs can impact the overall water quality in that region, potentially causing erosion and contamination and restricting the flow of local water systems. As a result, food companies have more control over reducing their water footprint by focusing on blue water impact.
How will impact scores be affected?
The Blue Water Usage metric is a more rigorous measure of a product’s environmental impact on water. Therefore, products will generally score lower for Blue Water Usage than for the current Water Usage metric.
This means that you may see a drop in the overall HowGood Impact Score for your products. However, it’s important to note that all food products are similarly affected, and the industry average for the HowGood Impact Score has decreased by 6 points, as a result of the update.
Which products will be most affected by the update?
Products or ingredients produced from crops that require significant blue water resources and are grown in locations with high blue water scarcity will have the lowest score for blue water impact, and thus their HowGood Impact Scores will be most affected. For example, almonds grown in California will score poorly for blue water usage.
You can take a look at the sales categories that are most affected below. This means that you can likely expect products in these categories to experience a 8+ point reduction in their HowGood Impact Score.
Fruit Spreads and Jams
Cookies and Snack Bars
Bread and Baked Goods
Other Desserts, Frozen
Baking Mix, Ingredients and Flour
Likewise, products in the following sales categories have been the least affected, with an average score drop of 3 points or less.
Eggs, Cold Case
Meat and Poultry - Shelf Stable
Plant Based Meat Alternatives, Frozen
Jerky and Meat Snacks
Oils and Vinegars
Seafood - Stable
Milk, Cold Case
Plant Based Meat Alternatives, Cold Case
Creams and Creamers, Cold Case
Plant Based Cheese
Plant Based Dairy Alternatives
Coffee and Hot Cocoa
Tofu, Cold Case
