Green Supplier Agreement Terms

Zoë and Bea’s Clause

Green procurement clauses and a checklist to make a standard supplier agreement focus on emissions across a value chain.

Skip to clause

Why use this?

Many companies such as Microsoft are pledging to be Carbon Negative by 2030. In order to achieve this, they will have to work across their value and supply chains to align them with this target.

How it promotes a net zero future

The clauses and checklist should encourage existing suppliers to “up their climate change game” and thus accelerate a greater number of businesses in their transition to net zero.

Draft Clauses for Green Supplier Agreement: 

Additional Definitions

(It is assumed that Supplier, Principal and Supplied Products will already be defined in the contract)

Carbon Footprint Standards means, for Organisational Carbon Footprints and Supply Chain Carbon Footprints the GHG Protocol Corporate Accounting and Reporting Standard, or [The GHG Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard] [or ISO 14064?], and for Product Carbon Footprints the GHG Protocol Product Life Cycle Accounting and Reporting Standard, or [ISO 14064] 

GHG Emissions means emissions of the greenhouse gases listed at Annex A of the 1998 Kyoto Protocol to The United Nations Framework Convention on Climate Change, as may be amended from time to time including: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), nitrogen trifluoride (NF3), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6) including Scope 1, 2, and 3 Emissions, in absolute value over a specified area and period of time, each expressed as a total in units of carbon dioxide equivalent (CO2e) and calculated in accordance with the Carbon Footprint Standards.

GHG Report means a report prepared by the Supplier in accordance with the requirements set out in Clause [3]

Net Negative means an organisation has achieved a Net Zero Target but has also created an environmental benefit by removing Greenhouse Gases from the atmosphere or reducing its GHG Emissions to the atmosphere such that the aggregated reductions and removals exceed the unabated emissions.

Net Zero Target means both a reduction of GHG Emissions from all operations including value and supply chains and a removal of GHG Emissions associated with carbon offsets acquired to address Residual Emissions of the parties by 2050 or sooner in order to achieve a balance between the parties’ sources and sinks of GHG in a calendar year and for each subsequent year thereafter and the goals of the Paris Agreement.

Offset means the purchase of the equivalent quantity of carbon credits from a project that has been verified in accordance with [insert name of voluntary standard] or from a United Nations Framework Convention on Climate Change (UNFCCC) clean development mechanism (CDM) [or [successor/ equivalent] UNFCCC mechanism] project, with a view to the offsets being additional, permanent and verifiable and shall, where possible, prioritise projects with long-lived storage methods which have low risk of reversal over centuries to millennia and that remove greenhouse gases from the atmosphere rather than avoid or reduce other parties’ emissions of greenhouse gases and that consider global equity and address wider social and ecological goals.

Organisational Carbon Footprint means total annual worldwide GHG Emissions from all the activities across the organisation, including energy used in buildings, industrial processes and company vehicles and including Scope 1, Scope 2, and Scope 3 Emissions. 

Product Carbon Footprint means total GHG Emissions over the whole life of the Supplied Products, from the extraction of raw materials and manufacturing through to its use and final re-use, recycling or disposal, including including those associated with the raw materials and services purchased by the Supplier in order to deliver the Supplied Products and Scope 1, Scope 2, and Scope 3 Emissions..

Residual Emissions means the GHG Emissions that are emitted after all reasonable efforts have been made by a party to reduce GHG Emissions from all operations including value and supply chains.

Scope 1, 2 and 3 Emissions means the three classifications of emissions in the GHG Protocol.

Scope 1 Emissions means all direct emissions from the activities of an organisation or under its control, including on site fuel combustion and emissions from chemical production in owned or controlled process equipment, refrigerant losses and company vehicles. 

Scope 2 Emissions means all indirect emissions from electricity purchased and used by an organisation where the emissions occur at sources owned or controlled by another company. 

Scope 3 Emissions means all indirect emissions other than Scope 2 Emissions, that are a consequence of the activities of an organisation, but occur from sources not owned or controlled by that organisation, including business travel, procurement, waste and water.

Supply Chain Carbon Footprint means total annual GHG Emissions associated with the raw materials and services purchased by the Supplier in order to deliver the Supplied Products 


Additional Recitals

(A) The parties [have signed up to the Race to Zero and] acknowledge their common intention in furthering  achievement of their respective [organisational Net Zero Targets] and alignment with the ultimate objectives of the Paris Agreement and related agreements, in particular pursuing efforts to limit global temperature increase to 1.5 degrees Celsius above pre-industrial levels and achieving net zero or net negative emissions by 2050 or sooner.
