Source products and services from green suppliers
The majority of carbon emissions are created ‘upstream’ and ‘downstream’ of most businesses.
This means they come from sources you don’t directly control, such as how suppliers make products and how customers use them.
One way of reducing these emissions is to source products and services from ‘green’ suppliers with a track record of low carbon operations.

Benefit from a greener supply chain
Investing in more sustainable supply chains can boost your appeal to customers, shareholders and potential investors.
This is because greener supply chains:
- can lead to growth and cost saving opportunities
- can enhance your business reputation
- help ensure future regulatory compliance
- can improve continuity of supply
- reduce your exposure to fossil fuel price volatility
According to a 2019 study, 85% of consumers are more likely to buy from a business with a reputation for sustainability than from a neutral company, assuming their prices were equal.
Start by working out your supplier emissions
Carbon Trust estimates that supply chains are responsible for 65 to 95% of most companies’ carbon emissions.
To reduce these you need to consider what happens before and after your business provides a service or makes a product.
This includes the supplier emissions produced by:
- creating the raw materials you use
- manufacturing the products you sell
- transporting materials and products to your business
- delivering what you sell to customers
- disposing of waste from your business activities
To reduce these emissions you first need to measure them. This will provide a baseline to compare against once you take action.
If you can’t measure specific emissions data, simply rank your suppliers by overall spend to help prioritise your efforts.
Ask your suppliers for emission data
Ask your supplier for any emission-related data they have, or if it’s possible for them to calculate it.
Some suppliers already know the carbon emissions created by their products and services.
In this case, they may be able to provide you with:
- a standardised spreadsheet if they are tracking their emissions internally within their business
- reports on their carbon emissions that have been verified by an outside source
- product certifications that verify the amount of carbon associated with your organisation or specific product
If this is not available, ask your supplier for raw data on energy inputs, such as how much fuel is used transporting their products to your business and what type of energy they use (renewables or fossil fuel).
Calculate supplier emissions yourself
You can calculate supplier emissions yourself if your suppliers do not have their own data.
For many sectors, there is industry average data you can use to get an idea of how much emissions are associated with a product or service.
To get started you will need an idea of the rough amount of materials and resources involved in what you purchase.
Each one has a ‘conversion factor’ that will help estimate the emissions associated with that material. There are pre-made spreadsheets and free software tools to assist.
You may choose from two types of calculation methods:
Set goals and get internal buy-in
Before engaging with external suppliers it’s important to get internal agreement on your emission reduction programme.
You need to define the boundaries of your programme and who will run it.
This includes:
- assigning responsibility with a job role or team
- deciding what service or product categories to start with
- working out the metrics and how you’ll collect data and measure progress
- getting support from senior management
- how supply chain efforts fit with your larger sustainability goals
Put in place a regular reporting schedule for scope 3 emissions. You will need to be consistent in your reporting to ensure accountability and demonstrate commitment.
Establish a supplier code of conduct
It can be helpful to set written standards for your suppliers, products and services.
These can form part of your business strategy. Post them internally or on your business website if relevant to the public.
Areas to focus on include:
- reducing energy or fuel consumption per unit of production
- optimising logistics and low carbon transport
- minimising waste generated in production
- improving recycling practices and products
This helps you to partner with suppliers that share the same values and goals where possible.
Ask suppliers about lower carbon options
Before sending surveys or requests for data, let your suppliers know about your programme and why it’s important.
This includes:
- the person or team responsible on your end
- how you will use and protect their data
- the survey schedule and how often you’ll be in touch
- what you can do to assist them in responding
- consequences of not participating
If you have set targets and milestones, communicate them with your suppliers. If suppliers can see the timeline and expectations of them going forwards it enables them to make a long term reduction plan as well.
Depending on the size of your business and number of suppliers, consider a training or information session to explain your programme and the survey process.
Prioritise your largest suppliers or those that might have the most room for improvement in their green credentials.
When you send out supplier surveys, consider:
- making it a web form so it’s easier to complete
- how you will ensure the quality of the data received
- how you will enter data into your record keeping system
- when to follow up with questions or next steps
Stay in regular contact with your suppliers to build your programme. It will take consistent efforts to build your data set.

Join a buying group to procure green products
It can be helpful to work together with other businesses to buy green products.
This increases your purchasing power and can help influence suppliers to change their practices.
The British Independent Retailers Association (BIRA) runs a buying group that helps members get better deals from suppliers.
Visit GOV.UK’s guide to buying groups for more detailed guidance.
