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 Oy “Good”. These are a few factors influencing its score:

  • It uses a medium proportion of lower-impact materials including recycled materials.
  • It uses lower-impact materials that help limit the chemicals, water, and wastewater in its supply chain.
  • It takes meaningful action to reduce emissions from transportation and distribution.
  • It avoids plastic packaging.
  • It provides Guppyfriend bags or similar options to help consumers capture the microplastics shed during washing.
  • 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 Oy “Good”. These are a few factors influencing its score:

  • All of its final production stage happens in Portugal.
  • It traces most of its supply chain.
  • It audits some of its supply chain including all of the final production stage.
  • 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 Oy 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 Oy “Good” overall.
