Public procurement represents one of the European Union’s largest economic instruments, with public authorities spending close to EUR 2 trillion each year, around 14% of EU GDP. This scale gives procurement significant potential to influence markets, accelerate climate action and support industrial competitiveness. Environmental considerations are permitted under the current EU framework, yet they remain unevenly applied and secondary to price-based decision-making. As a result, public purchasing has not fully contributed to emissions reduction, innovation or the development of low-carbon supply chains. Ongoing discussions on revising EU public procurement directives place renewed emphasis on transforming procurement from a compliance-driven process into a strategic policy tool aligned with climate and competitiveness objectives.
Voluntary Green Procurement Limits Impact
EU procurement rules allow environmental criteria to be included in tenders but do not require their use. This voluntary approach has led to fragmented uptake of green public procurement across member states. Only around one fifth of contracts above EU thresholds are classified as green and more than half of public contracts awarded between 2022 and 2025 relied solely on the lowest price as the award criterion. Existing mechanisms such as life-cycle costing and the Most Economically Advantageous Tender are available but remain underused due to limited obligation and inconsistent application.

The construction sector illustrates the scale of missed opportunity. Construction represents 5.5% of EU GDP and accounts for a significant share of procurement-related emissions. Public authorities are major purchasers of steel and cement, materials responsible for a substantial proportion of global greenhouse gas emissions. Estimates indicate that steel and cement used in EU public construction generated around 51 Mt CO₂ in 2019. Public procurement accounts for roughly 31% of cement demand and 11% of steel demand in the EU. Applying mandatory green criteria to these materials could deliver sizeable emissions reductions while increasing total construction procurement costs by only 1% to 2.2%.
Fragmentation and Legal Uncertainty Constrain Action
Legal complexity continues to limit the consistent use of procurement as a climate instrument. While Directive 2014/24/EU provides a legal basis for integrating environmental considerations at different stages of procurement, member states transpose and interpret the rules differently. This results in uneven practices, variable requirements and uncertainty for both procurers and suppliers. Sustainability obligations are increasingly embedded in sector-specific EU legislation, including requirements for clean vehicles, energy-efficient products and buildings and net-zero industrial goods. Inconsistent implementation across member states adds further complexity.
Contracting authorities often report uncertainty over how far environmental criteria can extend and how closely they must be linked to the subject matter of a contract. This requirement can restrict broader sustainability conditions, even when supplier practices influence environmental performance. Verification of equivalent ecolabels and certifications also presents challenges, as procurers must accept alternative proof while assessing comparability across fragmented standards. These factors contribute to risk aversion, particularly when audit practices prioritise cost control and procedural compliance over sustainability outcomes.
Reform Focuses on Mandatory Uptake and Capacity
Proposed reforms to the EU procurement framework centre on simplification and strategic use of public spending. A key shift would be to make green public procurement the default rather than the exception, supported by EU-wide targets and a comply-or-explain approach. Under this model, contracting authorities would apply environmental criteria in all tenders unless justified by limited market availability or demonstrably higher life-cycle costs. Early market engagement would help assess readiness and provide clearer demand signals to suppliers.
Reform proposals also emphasise aligning any European preference measures with environmental performance. Local procurement already dominates EU markets, with 40% of winning bidders located in the same region as contracting authorities. Evidence suggests that local content rules alone deliver limited climate or employment benefits unless combined with robust sustainability requirements. Linking procurement reform to emerging industrial policies, including low-carbon standards for materials such as steel and cement, is intended to support both climate goals and industrial resilience.
Improved monitoring and professionalisation are identified as essential enablers. Harmonised data systems would allow progress to be tracked and outcomes measured, while capacity-building initiatives would support consistent application of environmental criteria. Enhanced skills and clearer tools are associated with fewer delays, reduced administrative burden and more effective procurement outcomes.
EU public procurement holds significant potential to support climate objectives and industrial competitiveness, but voluntary and fragmented application of green criteria has limited its impact. Legal complexity, inconsistent implementation and limited monitoring continue to constrain strategic use of public spending. Proposed reforms aim to make green procurement mandatory, simplify rules and strengthen professional capacity, creating clearer demand signals for sustainable markets. By aligning procurement practices with environmental performance and long-term policy goals, public purchasing can become a more effective instrument for delivering measurable climate and economic benefits across the EU.
