How to improve your sustainable procurement policy with Life Cycle Assessment (LCA)

How to improve your sustainable procurement policy with Life Cycle Assessment (LCA)


A practical guide to making your procurement strategy more resilient to environmental and regulatory challenges.


Regulatory pressure on environmental data and the integration of Scope 3 (indirect emissions) into carbon footprints now place procurement teams at the forefront of corporate decarbonization.

Faced with growing demands, there is a temptation to multiply requests for justifications (carbon footprints, SBTi trajectories, product carbon footprints, etc.). But is this always relevant?

In this guide, we explore:



Demand more than decarbonization from your sustainable procurement policy

Why go beyond product carbon footprint?

Carbon footprint is often the first indicator used to assess a product’s sustainability. However, this analysis is incomplete: a product with a low carbon footprint may still have a high impact on ecosystems or water pollution for example.
LCA provides a holistic view by evaluating 16 environmental indicators (climate change, resource depletion, acidification, eutrophication, etc.). It meets the need for decarbonization analysis, while integrating other essential impacts for your CSR policy.

Target your impact reduction levers more precisely

In carbon accounting, procurement is often a "black box": at best, a generic emission factor; at worst, a monetary factor.
When certain procurement categories are significant, LCA comes into its own: it refines the product’s emission factor and can even drill down to the process level. This is the ideal lever for identifying your most contributing suppliers, not only in Tier 1 but across the entire value chain.



The challenges of integrating LCA into a tender process

Despite its benefits, integrating LCA into procurement processes faces several obstacles:

Data that is difficult for buyers to exploit

Tenders often end up concentrating all of a company’s expectations, and buyers can become overwhelmed with data:

A challenge for suppliers

Many suppliers, though willing, face difficulties in producing a product carbon footprint or LCA due to a lack of resources or data, the diversity of reference frameworks required by different clients, etc.
Requiring LCA results as early as the tender application phase can introduce bias, favoring large suppliers, often the only ones with the resources to produce these documents at this stage. This can create an imbalance in the client-supplier relationship, to the detriment of a genuine partnership on technical, financial, and environmental issues..
Moreover, if the product is still in the early stages of design, it may simply be impossible to conduct an LCA that is sufficiently representative of the final product!

Think beyond the tender process

To avoid these pitfalls, it is wiser to adopt a long-term approach:



How to integrate LCA into your procurement: methodology and best practices.

Step 1: Train and support procurement teams (and beyond)

First and foremost, it is essential to train all stakeholders involved in procurement (buyers, product managers, designers, etc.) on sustainable procurement issues:

Support from LCA experts for procurement teams at different stages of the procurement process can be particularly valuable, especially when starting the initiative.

Step 2: Refine the expression of needs and integrate the "total footprint of ownership" concept

Beyond the traditionally identified needs (technical, cost, quality, lead time), it is also necessary to integrate environmental performance:

Thus, the traditional "total cost of ownership" can be enriched to become "total footprint of ownership".
Once these elements are analyzed, they can be integrated into the procurement strategy.

Step 3: Engage suppliers in the long term

Depending on the impact mapping and the state of the supplier panel, several actions can be considered:

Procurement department: a key role

Procurement plays a central role in balancing price, performance, and environmental impact. Beyond the initial selection of a supplier for a given product, their mission also includes supporting ongoing negotiations to improve the environmental performance of the purchased product throughout its life cycle. This approach of continuous monitoring and dialogue transforms the supplier relationship into a lever for progressive improvement, rather than a one-off transaction



Toward 100% sustainable procurement?

Integrating LCA into your procurement is not an option but a necessity to meet regulatory requirements and stakeholder expectations. However, this approach must be progressive, collaborative, and pragmatic:
