Here's how we qualify products for Compact by Design:
To qualify for Compact by Design, products must belong to one of the specified product categories and have best-in-class “unit efficiency.” We use product attributes such as item package dimensions, item weight, and the number of units to calculate the unit efficiency of a product. Unit is defined as the total amount of product in the container we are evaluating. This is standardized across a product category, such as fluid ounces in cleaners and loads in laundry detergent.
Unit efficiency is calculated as (cubed volume per unit) x (weight per unit). This metric allows us to calculate the volume and weight utilization for the number of units a product delivers. In this equation, a lower unit efficiency value means a more efficient design. For example, a concentrated laundry detergent can deliver the same number of units (loads) in a smaller volume and weight than a non-concentrated detergent, resulting in a better unit efficiency.
