Artificial intelligence (AI) is poised to revolutionize sustainable public procurement —the process by which governments buy goods and services in ways that advance social, environmental, and economic goals. With public procurement amounting to one-fifth of global GDP (around $9.5 trillion annually), it offers immense power to reduce environmental impacts, promote equity, and foster economic development. Yet implementing sustainable public procurement remains slow and complex, hindered by regulatory uncertainty and operational barriers.

Why Sustainable Public Procurement Matters

Up to 96% of an organization’s climate emissions stem from supply chains, making procurement choices critical. Governments can drive sustainability by prioritizing products and services that meet goals in emissions reduction, resource efficiency, supplier diversity, fair labor, and local economic support. Despite international mandates, uptake has lagged due to the difficulties of integrating these factors into procurement processes.

AI Across the Procurement Lifecycle

Procurement involves vast amounts of data from sustainability reports, certifications, and regulations. AI can streamline and strengthen decisions at every stage:

1. Defining Needs and Market Assessment: Forecasting needs, flagging sustainability risks, and identifying market opportunities.
2. Tender Issuance: Automating drafting requests with built-in sustainability criteria.
3. Supplier Vetting: Reviewing audits certifications, monitoring performance, and detecting risks using real-time data.
4. Bid Evaluation and Selection: Providing transparent bid comparisons with AI scoring and anomaly detection.
5. Contract Management: Tracking compliance, milestones, and sustainability deliverables.
6. Process Review: Extracting lessons and best practices for continuous improvement.

Private-sector companies such as Sievo, EcoVadis, Interos.ai, and SupplyWisdom have developed platforms and tools which already demonstrate these applications, though government adoption is still emerging. Figure 1 demonstrates AI’s applicability to procurement lifecycle.

Challenges and Risks

AI-driven sustainable public procurement faces six major challenges. These are:

1. Data privacy and security risks in handling sensitive supplier data.
2. Bias and fairness risks of disadvantaging small or minority suppliers.
3. Transparency and accountability issues in AI’s decision-making processes.
4. Market power concentration among a few AI providers.
5. Fragmented responsibility across unregulated systems and stakeholders.
6. Sustainability of AI itself, given its high energy and water use.

To be effective, governments must address these challenges and risks with strong governance, a commitment to transparency, and robust regulation.

The Path Forward

AI could help governments operationalize climate goals in procurement by turning complex data into actionable decisions. Realizing this potential requires safeguards around fairness, data integrity, and accountability, while fostering collaboration between technical experts, procurement officials, and sustainability advisers.

Conclusion

AI is not just a tool but a strategic enabler for sustainable public procurement. If guided responsibly, it can transform public spending into a driver of sustainability, embedding climate and equity goals into everyday government practice.
