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

  • It uses a medium 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, its products are made to order.
  • 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 Frank Darling “It's a Start”. These are a few factors influencing its score:

  • Much of its final stage is located in low risk countries or certified facilities, however it does not publish an aggregate breakdown of suppliers.
  • It partly traces its final production stage, though not its entire supply chain.
  • There’s no evidence it has a Code of Conduct.
  • 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 Frank Darling 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 Frank Darling “It's a Start” overall.
