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 SO-LE Studio “Great”. These are a few factors influencing its score:

  • It uses a high proportion of lower-impact materials.
  • 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 manufactures its products closer to home to reduce the climate impact of long-distance shipping.

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 SO-LE Studio “Good”. These are a few factors influencing its score:

  • Its products are made in-house by the owner and a small team.
  • 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. Here we rate SO-LE Studio “Good”. These are a few factors influencing its score:

  • It appears to use leather.
  • A high proportion of its animal-derived materials consist of recycled or certified alternatives to conventional leather.
  • It doesn’t appear to use shearling, wool, cashmere, alpaca, mohair, or down.

Based on all publicly available information we’ve reviewed, we rate SO-LE Studio “Good” overall.
