What’s in a rating?

Evergrade rates the environmental impact of consumer products on a scale from 1 to 100 (where 100 is considered a sustainable product). The algorithm weighs five indicators and is based on scientifically backed research and data. We’ve done the work for you so you can make your purchase decisions thoughtfully and with the confidence that you’re getting quality goods that have a light footprint on our planet.

CARBON FOOTPRINT score for this product ishigh compared to other products on Everlastly.com

The Evergrade Carbon Footprint measurement is an estimate of the quantity of Greenhouse Gases (GHG) that are released into the atmosphere in the materials sourcing, production and transportation of a consumer product. It considers Carbon Dioxide, the biggest perpetrator of global warming, along with the equivalents (that’s the “e” in Co2e) for other harmful gases like Methane. While the measure is based on the product data we can obtain, it's a very good directional measure to understand emissions from the creation of this product.

PACKAGING efficiency for this product isaverage compared to other products on Everlastly.com

Your products need effective packaging so they won’t break in transport, but manufacturers can make good decisions to reduce the harmful effects of the materials used. We measure whether recycled materials were used in the packaging (what goes in), what percentage of the package is easily recyclable by the end consumer (what goes out), and whether any raw materials used were certified by a reputable environmental agency.

PREDICTED DURABILITY of this product ishigh compared to other products on Everlastly.com

Durability is perhaps one of the marquee elements of the Evergrade Rating system, yet seeing into the future to determine how long any product will last is still beyond our human capabilities. Ultimately, the longer a product lasts, the less impactful the environmental cost of creation is over time. We love companies that offer warranties on their products as it incentivizes them to create goods that will last a long time and not have to be replaced (at a cost to them), but in the absence of a warranty we look to the tensile or compressive strength of primary materials.

CERTIFICATIONS for this product rank isaverage compared to other products on Everlastly.com

Organizations that audit the environmental statements of a manufacturer do a lot to ensure that what’s being claimed can be verified. But complex supply chains and ever-changing material options have spawned no less than 4,000+ environmental certifications; that’s a big number for consumers to keep track of, not to mention which are legitimate and which can just be bought (sadly, there are some of those out there.) We track certification organizations and highlighted where manufacturers have done the work to ensure credibility in their good decisions.

CIRCULARITY ranking for this product isaverage compared to other products on Everlastly.com

Circularity refers to a system that reuses materials, as opposed to pulling them out of the ground and then dumping them into landfills. Data around recyclability is still hard to confidently measure given the varied recycling programs across municipalities. However, we value products that are using recycled materials in their construction or materials that will biodegrade at the end of their life. Everlastly is also a big proponent of Take-Back programs where manufacturers take responsibility for the product at the end of life, incentivizing them to create products that last longer and have parts that can be reused.
