Sustainable Public Procurement (SPP)

Sustainable Public Procurement (SPP) is a broader concept than Green Public Procurement (GPP). Where GPP focuses primarily on environmental outcomes, SPP asks contracting authorities to weigh environmental, social, and economic impacts together when designing and awarding contracts. The United Nations Environment Programme defines SPP as "a process whereby organisations meet their needs for goods, services, works and utilities in a way that achieves value for money on a whole-life basis in terms of generating benefits not only for the organisation, but also for society and the economy, whilst minimising damage to the environment."

What is Sustainable Public Procurement (SPP)?

SPP operates across three pillars:

Environmental. Reducing carbon emissions, cutting resource consumption, preventing pollution, and supporting circular material flows. Tools include Life-Cycle Assessment (LCA), Environmental Product Declarations (EPDs), and product ecolabels.

Social. Ensuring that contracted goods and services are produced under fair labour conditions, without child or forced labour, and with positive outcomes for local communities. This overlaps with Socially Responsible Public Procurement (SRPP) and, where relevant, Fair Trade in Public Procurement.

Economic. Delivering genuine value for money on a whole-life basis rather than simply minimising the purchase price. Whole-life costing under Article 68 of Directive 2014/24/EU is a key tool, capturing energy costs, maintenance, disposal, and external costs such as greenhouse gas emissions attributable to the product during its life cycle.

Directive 2014/24/EU provides authority for all three pillars. Environmental and social characteristics may be embedded in technical specifications (Article 42), selection criteria (Article 58), award criteria (Article 67), and contract performance clauses (Article 70). Labels, certifications, and third-party audits are expressly permitted as means of proof under Article 43, provided buyers also accept equivalent evidence.

In the UK, SPP is shaped by the Social Value Act 2012, the Procurement Act 2023, and Procurement Policy Notes from the Cabinet Office. Central government authorities must consider and explicitly evaluate social value in all contracts above threshold. The Deforestation-Free Supply Chain and Conflict Minerals Due Diligence requirements that are emerging in European regulation add further supply chain dimensions to SPP practice.

Why SPP matters for bidders

SPP raises the evidentiary bar. Suppliers competing on SPP-weighted contracts must be prepared to demonstrate not just price competitiveness but a credible environmental and social story backed by verifiable data. Authorities are increasingly asking for supply chain declarations, third-party audit certificates, and sustainability reporting aligned with frameworks such as the Corporate Sustainability Reporting Directive (CSRD).

Bidders who invest in robust sustainability management systems, who hold recognised labels and certifications, and who can produce life-cycle data on request are structurally better placed to win SPP-weighted contracts than those who treat sustainability as a box-ticking exercise.

Example

A Swedish regional authority procures catering services under an SPP framework. It requires as a minimum that 40% of food ingredients be organically certified (environmental pillar). As an award criterion, it scores an additional 15 points for suppliers with a Fair Trade sourcing policy for coffee and cocoa. As a contract performance condition, it requires the supplier to report quarterly on food waste volumes, with a contractual reduction target of 10% per annum.

Frequently Asked Questions

How does SPP differ from GPP?

GPP is a subset of SPP focused exclusively on environmental criteria. SPP adds social and whole-life economic dimensions. In practice, many authorities use the terms interchangeably, but SPP frameworks tend to include social value scoring, labour standards clauses, and community benefit requirements that pure GPP frameworks do not.

Can SPP criteria disadvantage SMEs?

Disproportionate certification requirements can create barriers for smaller suppliers who lack the resources to obtain third-party audits or compile detailed supply chain data. The remedy is proportionality: criteria should reflect the environmental or social risk of the specific purchase, not impose a blanket burden. European procurement rules require that criteria be proportionate to the contract, and buyers are encouraged to accept self-declarations for lower-risk purchases.

Is SPP reporting mandatory?

Reporting obligations vary. At EU level, the CSRD requires large companies and listed SMEs to disclose sustainability information, which in turn generates data useful for procurement assessment. Some member states require public authorities to report on SPP targets annually. In the UK, central government departments publish modern slavery statements and social value reports. Suppliers to such authorities increasingly face equivalent disclosure requirements flowing down through contract terms.
