Disclaimer on Transparency

We are currently doing an aggregation of available information to best inform the users on the environmental impact of garments. Since the fashion industry is very opaque, we are relying on publicly available information and research output. Therefore, our goal is to push brands to be transparent and provide consumers with more information.

Breakdown of our Impact Score

Changing Room’s Impact Score is calculated based on two different criteria: Brand Impact and Production Impact

1. Brand Impact

As a proxy of brand sustainability commitment and impact, we are relying on reputable sources (e.g. Good on You, BoF Index, Fashion Revolution) that rate brand supply chains. The criteria are on social rights (i.e. workers treatment), environmental commitment, and transparency.

Some questions being asked:

Are brands relying on solar energy or fossil fuels?

Are they using a lot of harmful chemicals in their dying process?

What are their commitments to reduce their harmful environmental impacts?

Brand Impact considers:

people

Social Impact

Considers a brand’s fair labor practices + policies across the supply chain

Planet Health

Considers a brand’s resource + waste management policies + impact across the supply chain

2. Production Impact

Production impact is further broken down into two components: environmental impact in the production process of clothes and waste impact incurred by different materials.

We estimate the environmental impact of the production of clothes (from farming to weaving and dyeing) by combining Higg’s Index on material sustainability impact and research papers on the life cycle assessment of different materials.

We also created our own waste impact measurement to consider the impact incurred from using the product and its end-of-life impact, such as the product’s renewability, recyclability, biodegradability, and microplastic pollution potential.

Some questions being asked:

Are brands relying on social energy or fossil fuels?

Are they using a lot of harmful chemicals in their dying process?

What are their commitments to reduce their harmful environmental impacts?

Production Impact considers:

Environmental Impact

footprint

Carbon Footprint

Considers a material’s greenhouse gas emissions + fossil fuel depletion across the supply chain

water

Water

Considers material’s water use + eutrophication potential across the supply chain.

Waste Impact

footprint

Renewability

Considers whether a material is derived from a renewable or non-renewable resource (e.g., cotton agriculture vs. fossil-fuel based plastic)

Recyclability

Considers whether a material (or combination of materials) can be easily recycled into a new product or fiber (e.g., 100% cotton vs. cotton/poly blends)

Biodegradability

Considers whether a material can safely degrade into basic organic elements through enzymatic digestion from microorganism like bacteria and fungi

Microplastic Pollution

Considers whether a material sheds microplastic filaments into soil and water systems throughout wash, wear, and disposal
