Qualify for Compact by Design

Compact by Design is a new sustainability certification created by Amazon to identify products that, while they may not look very different, have a more efficient design. With the removal of excess air and water, products require less packaging and become more efficient to ship. At scale, these small differences in product size and weight lead to significant carbon emission reductions.

There is no application process for Compact by Design as we use existing product attributes to evaluate items for inclusion. There is also no fee for inclusion in Compact by Design.

To qualify for Compact by Design:

  • Your product must be in a product category that is included in the Compact by Design certification.

    Note: You can visit our Compact by Design page to see the most up-to-date list of qualifying categories.

  • The unit efficiency of your product must be more efficient than the product category threshold (see section below).
  • The brand must be registered with Brand Registry.

Calculating unit efficiency

We use product attributes like item package dimensions, item weight, and the number of “customer uses” a product can deliver. “Customer use” is a unit of measure for a particular product.

It varies by product - the customer uses of a shampoo are determined by the volume (fl. oz.) whereas the uses of a laundry detergent is in loads. This “use” unit is typically the “unit count” in your product catalog.

The dimension attributes of all products in a category are normalized to inches and pounds, and then all the attributes are used in our unit efficiency equation:


Example of how to calculate unit efficiency for a bottle of laundry detergent:


We then compare each product’s unit efficiency with that of the category threshold. Established products with a unit efficiency below the category threshold will qualify for Compact by Design. You can view thresholds for each category by visiting the Compact by Design page.

Calculating unit efficiency of concentrated products:

For products where a customer has to add water prior to use, like concentrated cleaners, we have introduced a new catalog attribute, equivalent_product_volume. Equivalent product volume is meant to capture the use cases that aren’t accurately represented in the standard product attributes and is used in place of “uses” in our unit efficiency equation.


Equivalent Product Volume: The total product volume after mixed with a liquid or when converted to an equivalent product's form. This would differ from what might be populated in the unit_count attribute, as unit_count would display the shipped volume of the product while this attributes displays the “usable” volume of the product when un-concentrated or mixed with the appropriate amount of liquid.

An example of a product where the attribute equivalent product volume is relevant is a concentrated household cleaner that requires the end user (the customer) to dilute it prior to use. In this example, 16 fl. oz. of a concentrated cleaner, when diluted, may produce 64 fl. oz. of cleaner a customer can use. So, 64 fl. oz. would be the equivalent product volume.

You can edit the equivalent product volume attribute only for categories that have products that the customer would add water to, for obtaining the final volume, like concentrated cleaners or powdered drink mixes.

See below, an example of how to calculate Equivalent Product Volume:

Example product: 32 fl. oz. concentrated cleaner.

Instructions are to dilute 2 fl. oz. of the cleaner with 1 gal (128 fl. oz.) of water before using.
