A PRACTICAL APPROACH TO ACCELERATING SUPPLY CHAIN DECARBONIZATION
The Supplier Cascade gives businesses a manageable way to address Scope 3 emissions through Tier 1 supplier engagement. Built from best practice, it focuses on enabling action in the areas that are within a business’s control.
Organizations create tangible climate action by asking their Tier 1 suppliers to make a credible net zero commitment aligned with science, publicly report their progress against targets, and cascade the approach to their own Tier 1 suppliers and beyond. The Supplier Cascade can create a domino effect of climate action as each subsequent tier of the supply chain asks its own Tier 1 suppliers to take action.
Please join us to create tangible climate action throughout the supply chain.
Created in partnership with BSR, CDP, Ceres, Environmental Defense Fund and SME Climate Hub, and in collaboration with the Science Based Targets initiative.
WHY USE THE SUPPLIER CASCADE?
Action-oriented: companies need not wait for challenges around accurate Scope 3 emissions data to be solved
Evidence-based: built from best practice and backed by research and consultation
Focused: Tier 1 suppliers are asked to make credible climate commitments and cascade the same action onwards
Measurable: prioritizing metrics that are within an organization’s control
Straightforward: no deep technical knowledge required, enabling implementation by procurement teams
Flexible: businesses can engage and incentivize their suppliers however they choose
Cost saving: buyers support a unified ask, saving suppliers resources from responding to bespoke requests
Scalable: the approach generates climate action far beyond an organization’s own supply chain

How it works
Businesses ask their Tier 1 suppliers to make a credible net zero commitment that is science-based and aligned with the 1.5°C goal set out in the Paris Agreement. Businesses have complete flexibility and freedom in the way they incentivize their suppliers.
Tier 1 suppliers continue the cascade by asking their own Tier 1 suppliers (also called Tier 2 suppliers by the original business) to make a credible net zero commitment.
Tier 1 suppliers who have made net zero commitments report progress against their targets annually, so customers can access public primary data on emissions reductions in their supply chain.
Businesses also report annually on supplier action progress: – the number of their Tier 1 suppliers that have made a credible net zero commitment, and those that have cascaded the approach.
Through publicly accessible and comparable reporting, businesses share what they are doing and encourage others to act.

Businesses of all sizes and from all sectors have committed to starting their own Supplier Cascade. Join them as an Early Adopter to contribute to the discussion and receive tailored support in taking control of upstream Scope 3 emissions.
A credible net-zero commitment should be science-based and aligned with 1.5°C. The most ambitious are a commitment or validated target with the Science Based Targets initiative (either near term target or Net-Zero Standard) or, for small and medium-sized enterprises (SMEs), making the SME ClimateCommitment.
The Supplier Cascade provides an approach for addressing upstream supplier emissions associated with fuel combustion and purchased electricity.This approach does not cover other types of Scope 3 emissions (e.g., downstream emissions, those associated with land-use change, emissions from farm fields).
No, businesses need to understand all material sources of Scope 3 emissions and use this approach in conjunction with strategies to reduce other sources of Scope 3 emissions (e.g., downstream emissions, those associated with land-use change, emissions from farm fields).
Businesses should ask all Tier 1 suppliers to adopt the Supplier Cascade approach, but if there is a need to prioritize support then businesses can start with those that represent the biggest spend. Best practice is that a majority of Tier 1 suppliers by spend are required or incentivized to adopt the approach within the first two years of implementation.
Best practice is to annually report to CDP if a business has made a science-based target, or the SME Climate Hub if they have made the SME Climate Commitment, as both these platforms allow data to be publicly reported. Businesses can also collect data as part of their existing supplier survey processes.
In the future, it is likely that the capacity to track the cascade will be built out further to include the percentage of Tier 1 suppliers who are also asking their own Tier 1 suppliers to set a credible net-zero commitment.
Businesses who would like to be an Early Adopter will have access to the coalition of NGOs who developed the approach if they have questions and/or need guidance. In return, they will be asked to share feedback and data from the implementation of the approach with the coalition of NGOs so that its efficacy is understood and can be used to inform subsequent guidance.
Early Adopters will be eligible to participate in future Supplier Cascade events highlighting their progress and will get access to a dashboard showing their progress against anonymized progress other businesses are making in implementing the approach.
