Sourcing agent

Using a sourcing agent can be an effective way to find ethical and green suppliers that you might struggle to identify yourself.

How to evaluate a supplier

Before you sign a contract with a new supplier, you should evaluate its environmental performance. Ways to do that include:

Company information

Find information about the supplier’s environmental policies and practices. You could look at the company’s annual reports, mission statements and corporate social responsibility pages on its website.


Check if the company has been audited by an industry standards body for standards such as ISO 14001 opens in new window or is an accredited member of an ethical scheme, such as World Fair Trade Association opens in new window, Better Cotton opens in new window, Worldwide Responsible Accredited Production opens in new window, Green Mark opens in new window and Green Accord opens in new window.

Product labelling

Check that products provided by the supplier have a label or logo that identifies them as environmentally friendly. There are a wide range of schemes in operation worldwide with various criteria. You should decide which one is right for you and your customers. Examples include EU Ecolabel opens in new window, Soil Association opens in new window, EU organic logo opens in new window and Global Ecolabelling Network opens in new window.

Customer testimonials

Request to speak to some of the potential supplier’s existing customers or look for them on LinkedIn. Ask them to verify the supplier’s green credentials.

Compliance with the law

Check that the supplier has not been prosecuted for breaking any environmental regulations.


If the products or materials you intend to purchase will be shipped in packaging, make sure that the packaging is as sustainable as possible and kept to the absolute minimum.

Energy efficiency

Check how energy efficient the supplier is, such as how much power and water is used to make the products.

If you decide to do business with the supplier, seek legal advice and draw up a service level agreement that covers areas such as the responsibilities of both parties, the service that the supplier must deliver, metrics for how service levels will be measured and delivery schedules. You can also include the supplier meeting your expectations on green and ethical practices.

What to look out for

‘Greenwashing’ is the act of making false or misleading claims about the environmental benefits or sustainability of a product or service. When selecting your suppliers, this is something to bear in mind as they might not be as green as they claim.

Red flags to look out for include:

  • Vague or unclear terms such as ‘green’, ‘eco’ and ‘all natural’ without adequate explanation or evidence to back up the claim.
  • Descriptions that could be misleading. For example, ‘100% recycled’ does not mean the same as ‘100% recyclable’.
  • Use of logos or labels that are not associated with an official accreditation organisation.
  • Claims that don’t comply with sector-specific laws. For example, bread labelled ‘organic sourdough’ would be misleading if at least 95% of the ingredients were not organic.

If you use a supplier that is making false claims, you could get into trouble yourself. The Competitions and Market Authority (CMA)Opens in a new window is reviewing different consumer sectors for evidence of greenwashing.

The CMA’s green claims checklistOpens in a new window is a helpful resource for checking the validity of environmental-related claims.
