Our ratings are based on a scale from 1 (We avoid) to 5 (Great) How we rate


Our “Planet” rating evaluates brands based on the environmental policies in their supply chains, from carbon emissions and wastewater to business models and product circularity. Here we rate Thunderpants US “Great”. These are a few factors influencing its score:

  • It uses a high proportion of lower-impact materials including organic cotton.
  • It uses lower-impact materials that help limit the chemicals, water, and wastewater in its supply chain.
  • To minimise waste, it limits its production runs.
  • It takes meaningful action to reduce emissions from transportation and distribution.
  • Its packaging is recyclable.

Workers’ rights are central to our “People” rating, which assess brands’ policies and practices on everything from child labour to living wages and gender equality. Here we rate Thunderpants US “Good”. These are a few factors influencing its score:

  • All of its final production stage happens in the United States of America.
  • It audits some of its supply chain including all of the final production stage.
  • It traces most of its supply chain.
  • There’s no evidence it ensures workers are paid living wages in its supply chain.

Brands’ animal welfare policies and, where applicable, how well they trace their animal-derived products are the focus of our “Animals” rating. Since Thunderpants US makes products that are generally free of animal-derived materials, we have not rated its impact on animals. Its overall rating is based on its combined "Planet" and "People" scores.

Based on all publicly available information we’ve reviewed, we rate Thunderpants US “Good” overall.
