This table explains the areas and issues that Good On You assesses when rating fashion brands, and the impact of these issues.

Planet

Area

Issue

Description

Resource use

Materials

Whether brands use fabrics with lower environmental impacts. We encourage brands to publish estimates of fibres used across 12 months based on purchased fabrics (preferred), sold fabrics, or their available collections. Brands with a higher proportion of lower-impact fibres, such as organic cotton, will score higher than brands that use smaller quantities.

Circularity

Business models and design decisions. Certain fashion business models drive unsustainable consumption practices that lead to excess waste and pollution. We reward business models that focus on slow fashion and circular principles that seek to design out waste and pollution and keep products and fibres in use for as long as possible, including through reuse and recycling. We also evaluate brands that operate high-production and consumption business models, such as fast fashion brands. These brands often have mass sales, regular new arrivals, on-trend designs, and low price points. 

Microfibres

Information on brands’ initiatives to avoid or reduce the discharge of microfibres, both pre-consumer and during the consumer-use phase. Synthetic fibres such as polyamide and polyester (including recycled versions) discharge microplastics into the environment, particularly during machine washing.

Packaging

The packaging brands use and how they address its environmental impacts. We look at the components of the packaging, such as whether it is made from recycled materials, and the steps the brand has taken to minimise the use of packaging in the first place, as well as eliminating plastic packaging.

Non-textile waste

How brands avoid or minimise non-textile waste in their direct operations and across the supply chain, taking into account the relevant certifications.

Deforestation

The steps brands take to avoid or minimise deforestation from the use of fabrics associated with deforestation, including leather, rubber, metal, precious stones, and cellulosic fibres. Brands are expected to have a policy with clear mechanisms of implementation that avoid deforestation for all at-risk fibres.

Biodiversity

How brands avoid or minimise impacts on biodiversity in their supply chain. Brands are expected to have policies that include regenerative approaches to agriculture that restore soil and grasslands, protect waterways, and ensure conservation of impacted species.

Climate change

CDP disclosure

Whether brands disclose to CDP and if they do, what their CDP Climate score is.

Measurement

Whether and how brands measure greenhouse gas emissions across their direct operations and value chain, taking into account any relevant certifications. Brands are expected to identify and measure the emissions that have the largest impact in their supply chain. Brands are also expected to collect primary data from their suppliers for more accurate emissions figures.

Reduction

The steps brands have taken to reduce greenhouse gas emissions, taking into account any relevant certifications. We look at where in the value chain the emissions reductions occur, with a particularly strong focus on the supply chain. Making products by hand, using renewable energy, local manufacturing, and energy efficiency projects are some of the actions that brands can take to reduce their climate impact. 

Targets

Brands’ greenhouse gas emission reduction targets, taking into account any relevant certifications. We reward brands that set ambitious targets that cover their direct operations and particularly their supply chain. Brands are rewarded for setting Science-Based Targets.

Progress v target

Whether brands report progress against their targets to reduce greenhouse gas emissions across their supply chain. It is important that a brand sets ambitious targets, but even more critical is that it demonstrates that it has or will actually meet that target.

Chemicals

Hazardous chemicals

How brands reduce the use and impact of hazardous chemicals in their supply chain, including specific issues related to working with leather and footwear if applicable, and taking into account any relevant certifications. We expect brands to go further than eliminating chemicals hazardous to human health and also set targets and actions to eliminate chemicals hazardous to the environment throughout their supply chain.

Policies

Policies on chemical use, taking into account any relevant certifications. Brands are expected to have a manufacturing restricted substances list aligned with ZDHC or equivalent standard, and be working towards ensuring it is met throughout their supply chain.

Leather tanning

How brands avoid or minimise the impact of chromium and other chemicals in leather production, taking into account any relevant certifications. This criterion is weighted more heavily for brands where leather is a dominant fabric used in their production. 

Solvent use

How brands avoid or minimise the impact of solvent-based chemicals used in shoe production, taking into account any relevant certifications. This criterion is weighted more heavily for brands where shoes is a dominant category sold in their production. 

Water

CDP disclosure

Whether brands disclose to CDP Water and if they do, what their CDP Water score is.

Local impact

Brands’ impact on water use across the supply chain. Water issues manifest themselves at a local water basin level. Brands are expected to trace their suppliers and determine whether they are operating in water basins with high levels of water stress.

Stakeholders

How brands engage with stakeholders to manage water issues in the value chain. Brands are expected to engage with their suppliers and other key stakeholders, particularly in water basins with higher levels of water stress.

Targets

Brands’ targets for reducing water use across their supply chain.

Reduction

Brands’ initiatives to reduce water use across the supply chain, taking into account any relevant certifications. Specifically, water initiatives where there are higher levels of water use such as the wet processes stages of the supply chain and the raw primary stage. 

Measurement

How brands measure water use across the supply chain, taking into account any relevant certifications.

Wastewater management

How brands manage wastewater and treat effluent across the supply chain, taking into account any relevant certifications.

Citizenship

Citizenship

The actions brands take as corporate citizens to address environmental harm related to fashion including innovation, advocacy, and remediation of negative incidents.

People

Area

Issue

Description

Supply chain risk

Traceability

The extent to which brands are able to trace suppliers. Brands are expected to trace beyond just the final production stage and include primary and secondary suppliers to best manage their impact and ensure workers’ rights.

Transparency

How transparent brands are about their suppliers across the full supply chain, including whether they publish details such as the country of manufacture, supplier names and contacts, number of employees, and raw fabrics used.

Labour rights and abuse risks

How brands’ choice of supplier location and industry standards impacts the risk of labour rights abuse in the supply chain.

Policies

Code of conduct

Labour policies covered in the supplier code of conduct, taking into account any relevant certifications. At a minimum, brands should have a code of conduct that covers all of their supply chain and includes the ILO Principles.

Modern slavery

The actions brands take to avoid modern slavery across the supply chain, taking into account any relevant certifications.

Financial security

Whether brands ensure financial security for their suppliers, which helps avoid poor working conditions and wages in the supply chain. Long-term contracts offer suppliers stable, predictable income, enabling investment in their workforce.

Gender, diversity, and inclusion

The diversity and inclusion policies and practices, both in direct operations and across the supply chain. This includes brands’ approach to discrimination on the basis of race, gender, age, sexuality, ability, and socioeconomic status. We expect brands to demonstrate the mechanisms and tools to ensure that their policy is met, with particular weighting to brands that demonstrate tangible results as an outcome from those mechanisms.

Sandblasting

Whether brands offer distressed denim, and if they do, their approach to sandblasting.

Assurance

Worker empowerment

How brands support the right to freedom of association and other ways to empower workers across the supply chain. We also evaluate what proportion of workers are members of collective bargaining groups or unions, and how the brand engages with those groups to ensure stronger worker outcomes.

Auditing

Any relevant certifications and what proportion of the supply chain is covered. Social auditing is designed to ensure that the policies and standards brands expect of their suppliers are adhered to.

Supplier relationships

How brands support suppliers to avoid labour rights abuses and to promote respect for workers and fair wages. We look for brands that may be partnering with artisans or independent makers, and ensure that the brand and workers have a balanced and equal working relationship. We also look at brands that may be set up with an explicit purpose to engage with underrepresented workers and communities.

Grievance mechanism

The formal processes implemented for workers in the supply chain to raise complaints, harassment, or other issues related to their working conditions and rights.

Living wage
