Life-Cycle Assessment (LCA) in Procurement

Life-Cycle Assessment (LCA) is the internationally standardised methodology (ISO 14040 and ISO 14044) for measuring the environmental impacts of a product, service, or process across every stage of its existence. In a procurement context, LCA provides the quantitative foundation for comparing competing bids not just on purchase price but on their full environmental burden, from the extraction of raw materials through manufacturing and distribution, the use phase (including energy and water consumption), maintenance, and finally disposal, recovery, or recycling.

What is Life-Cycle Assessment (LCA) in Procurement?

Article 68 of Directive 2014/24/EU expressly permits contracting authorities to base award criteria on the life-cycle costs of the works, supplies, or services being procured. Life-cycle costing under Article 68 includes both financial costs (purchase price, operating costs, maintenance, disposal) and, where a methodology for monetising environmental externalities has been established, the costs imputed to environmental impacts such as greenhouse gas emissions and air pollution.

LCA underpins several procurement instruments:

Technical specifications. Requirements drawn from LCA evidence, such as a maximum embodied carbon per square metre of floor area for construction, or a maximum global warming potential (GWP) per unit of production for industrial products, translate LCA findings directly into minimum compliance thresholds.

Award criteria. Scoring based on quantified environmental performance, where bidders submit LCA-derived data and are scored relative to a defined baseline. The Comprehensive GPP Criteria for several product categories already incorporate LCA-based award scoring, particularly for embodied carbon in construction materials.

Environmental Product Declarations (EPDs). EPDs are standardised, third-party verified documents that communicate the results of an LCA for a specific product, following EN 15804 for construction products or ISO 14025 for other product categories. They are the primary mechanism for supplying LCA data in a bid.

Whole-life costing. LCA data feeds into life-cycle cost models by quantifying use-phase energy consumption and emissions. A product with a higher purchase price but lower energy consumption over its service life may have a superior life-cycle cost, making it the better value award under an Article 68 analysis.

LCA methodology distinguishes several system boundary options. A "cradle-to-gate" LCA covers extraction and manufacturing only. A "cradle-to-grave" LCA includes the use phase and end of life. A "cradle-to-cradle" LCA models recovery and re-entry into the production system. Procurement authorities using LCA-based criteria should specify which system boundary applies and which impact categories are assessed, typically at minimum global warming potential (GWP), acidification, and resource depletion.

In the UK, the Infrastructure and Projects Authority and HM Treasury guidance on whole-life value supports LCA-based costing for major capital projects. The UK Net Zero Strategy commits central government to measuring and reducing the whole-life carbon of its procurement, making LCA an increasingly mainstream tool in major construction and infrastructure tenders.

Why LCA matters for bidders

LCA competence is becoming a competitive necessity for suppliers in high-value European public markets. Authorities adopting Comprehensive GPP Criteria or carbon reduction targets increasingly require bidders to submit product-specific EPDs or LCA reports as part of their technical submission. Suppliers without this data are excluded or score zero on environmental award criteria, regardless of their actual environmental performance.

Investing in a third-party verified EPD or a certified LCA study is a one-time cost that provides reusable evidence across multiple tender responses. Suppliers in construction, manufacturing, IT equipment, and chemicals sectors should treat LCA documentation as core tender collateral.

Example

A Norwegian roads authority issues a tender for asphalt supply and sets a Comprehensive GPP award criterion: bids scoring the lowest GWP per tonne of asphalt produced (as declared in a third-party verified EPD) receive the maximum environmental score. Three bidders submit EPDs. Bidder A declares 45 kg CO2e per tonne, Bidder B declares 38 kg CO2e per tonne, and Bidder C declares 52 kg CO2e per tonne. Bidder B receives the full environmental score; Bidders A and C are scored pro rata. Combined with price, Bidder B wins despite a slightly higher unit price.

Frequently Asked Questions

What is the difference between LCA and carbon footprint?

A carbon footprint measures greenhouse gas emissions only, expressed in CO2 equivalent. An LCA is broader, assessing multiple impact categories simultaneously, including water use, eutrophication, acidification, and resource depletion, in addition to climate change. Many procurement criteria focus on GWP (the climate change impact category) as a proxy for environmental performance, making the distinction practically slim for many bids, but full LCA data is required when criteria extend beyond carbon.

Do I need a new LCA for every tender?

Not necessarily. A product-specific EPD is valid for up to five years and can be reused across multiple tenders, provided the product and manufacturing process have not materially changed. Where a buyer specifies a project-specific system boundary or impact category combination not covered by an existing EPD, a supplementary study may be required.

What standards govern LCA in EU procurement?

ISO 14040 and ISO 14044 govern LCA methodology generally. EN 15804 governs EPDs for construction products. ISO 14025 governs type III environmental declarations for other products. EU GPP Criteria documents specify which standards and verification requirements apply to the LCA evidence they accept.
