How we rate

Behind-the-scenes
(of our bullsh*t detector)

We rate products on a scale of 1-10, based on six environmental footprints and real reviews. Our algorithm analyzes data from 250+ sources.

Climate footprint icon

Climate footprint

The carbon dioxide and other greenhouse gases that are directly or indirectly released into the atmosphere by a product when it is made or used.

Water footprint icon

Water footprint

The amount of water that is used to make and use a product, and the vulnerability of the watershed that the water is pulled from. This accounts for water scarcity in the area, whether the product contributes to that risk and/or pollutes the local water supply.

Human well-being footprint icon

Human well-being footprint

The level of toxicity of a product, including if it is detrimental to you and your family's health and/or to the workers who make it. This also accounts for the treatment of workers along the supply chain and their working conditions.

Ecological footprint icon

Ecological footprint

The impact a product has on biodiversity, including the extent to which it harms or benefits local ecosystems and the natural habitats that plants and animals rely on.

Waste footprint icon

Waste footprint

The waste created by a product and its packaging, which is the result of how it is manufactured, how long a product lasts and how likely it is to be reused, recycled, or landfilled. This also accounts for whether that waste is hazardous.

Raw materials footprint icon

Raw materials footprint

The materials that are used to make a product, which accounts for how rare they are, whether they are renewable, how difficult they are to source, and how environmentally damaging it is to collect them.

REAL REVIEWS icon

REAL REVIEWS

The functionality, quality, and practicality of a product based on aggregated, anonymized reviews scraped from Amazon. What's the point of a product that's better for the planet if it doesn't work well?
