The challenge of reaching Net Zero requires wide scale collaboration across the economy. That is why supply chain engagement should be a key part of your sustainability strategy.
With scope 3 emissions often accounting for the biggest portion of an organisation’s carbon emissions footprint, you will need to build healthy and constructive relationships across your upstream and downstream supply chain in order to start addressing them.
Our supply chain engagement service allows you to connect with your suppliers and accelerate the delivery of your strategic objectives.

Supply chain engagement provides the information you need to prioritise efforts and engage suppliers to take action on Net Zero and sustainability

Supply Chain Engagement
What you need to know
Supply chain engagement is much more than just collecting data from your supply chain.
Effective supply chain engagement is about collaboration through providing decision-useful information to you and your suppliers. The engagement process provides critical information, supporting decision making in relation to your scope 3 emissions and supports your own engagement with your suppliers.
How does supply chain engagement move you closer to Net Zero?
Scope 3 emissions often represent between 80-95% of GHG emissions.
Supply chain engagement creates a deeper understanding of how to decarbonise your supply chain emissions and prioritise efforts.
How we can help
We run our supply chain engagement through our Net Zero Hub platform, which provides insight and oversight to you on suppliers Net Zero journey’s and their wider ESG agenda against industry best practice, with the flexibility to request basic and complex information from suppliers.
As part of the assessment of the supply chain, we will make recommendations based upon findings which feed into a number of other areas including:
- GHG Reporting
- Net Zero Strategy development and Scenario Modelling
- Risk and Opportunity reviews
- Sustainability disclosure (e.g. CDP & TCFD)
- Your Net Zero management system
Supply Chain Engagement FAQs
Scope 3 emissions are the indirect emissions within your value chain, upstream and downstream. They include emissions from purchased goods, employee travel, and product use and disposal. Unlike Scopes 1 & 2, Scope 3 requires collaboration with suppliers and customers to measure and reduce emissions. Whilst not all Scope 3 emissions are directly under your control, they are still your responsibility.
Key challenges include:
- Collecting accurate data across your value chain.
- Influencing suppliers and customers to adopt sustainable practices.
- Prioritising emissions hotspots for impactful reductions.
Collaborative approaches work best, such as:
- Offering training and tools to suppliers.
- Conducting joint lifecycle analyses to identify reduction opportunities.
- Encouraging suppliers to implement their own Net Zero strategies.
Life Cycle Analysis identifies emissions hotspots across a product’s lifecycle. This helps you target interventions, such as redesigning products, reducing material use, or improving energy efficiency.
