Nature-Positive Procurement in Transport Infrastructure
Transport infrastructure procurement now includes biodiversity as core requirement
Biodiversity protection in transport projects has historically been treated as a late-stage safeguard, addressed after decisions on location, design, and contractors were already locked in. A new initiative is changing that approach. The International Institute for Sustainable Development now leads a project to embed nature-positive principles directly into procurement processes for roads, rail, ports, and other major infrastructure.
The work sits within the Greening Transportation Infrastructure Development Integrated Program, a Global Environment Facility-funded effort led by WWF-US alongside the Asian Development Bank and the UN Environment Programme. IISD manages the procurement workstream specifically. The program operates across Malaysia, Nepal, the Philippines, Suriname, and Ukraine.
For UK businesses involved in international transport contracts or working with development banks, this represents a material shift. Biodiversity criteria are moving from optional environmental enhancements to mandatory procurement standards. Consequently, suppliers will need to demonstrate nature-positive credentials earlier in the bidding process, not as retrospective mitigation.
The initiative matters because procurement determines what gets built and how environmental requirements are enforced in practice. Once contract terms are agreed, environmental redesign becomes prohibitively expensive. Therefore, integrating biodiversity at the procurement stage shapes outcomes more effectively than post-approval adjustments.
Procurement framework replaces safeguard-only approach to biodiversity
IISD describes the project as building an evidence base for nature-positive transport procurement through several interconnected components. These include a blueprint for integrating biodiversity across procurement cycles, structured dialogues with development banks and government procurement teams, policy briefings, documented case studies, a technical handbook, and an online training program.
The blueprint provides standardized guidance on incorporating biodiversity assessments into tender specifications, supplier evaluation, and contract performance clauses. Previously, environmental considerations were often limited to compliance checks late in project development. This framework requires biodiversity impact to be assessed before site selection, during design, and throughout contractor evaluation.
Dialogues with development banks focus on aligning lending criteria with nature-positive procurement standards. Many infrastructure projects receive funding from institutions like the Asian Development Bank, which can require borrowers to meet specific environmental criteria. However, enforcement depends on how clearly those criteria are written into procurement documents and contract terms.
The technical handbook aims to give procurement officers practical tools for evaluating biodiversity impacts. This includes guidance on reading ecological surveys, comparing supplier environmental performance, and writing contract clauses that require nature-positive outcomes. The training program will support procurement teams in applying these methods consistently.
Case studies document how biodiversity considerations have been integrated into real transport projects. These provide evidence of what works in practice, helping procurement teams understand implementation challenges and solutions. For example, case studies might show how tender scoring was adjusted to reward suppliers with better environmental credentials, or how contract terms required habitat restoration alongside construction.
Five countries test nature-positive procurement in live infrastructure projects
The GRID IP program supports national pilot projects in five countries, each testing how nature-positive procurement applies to different transport contexts. Malaysia, Nepal, the Philippines, Suriname, and Ukraine provide diverse environments where biodiversity pressures vary significantly. Mountain roads in Nepal face different ecological risks than coastal ports in the Philippines.
Each national project must integrate biodiversity criteria into existing procurement frameworks. This means working within local regulations, adapting international guidance to domestic legal requirements, and training government procurement teams. The complexity varies by country. Some already have environmental assessment systems; others need to build capacity from scratch.
Development banks involved in these projects will apply lessons learned to future lending. If biodiversity procurement standards prove effective in pilot countries, they could become routine requirements for transport infrastructure financing globally. This would create new compliance expectations for contractors and consultants bidding on bank-funded projects.
For UK firms active in international infrastructure markets, these pilot projects preview requirements likely to spread. Companies that understand how to document biodiversity impact, propose nature-positive design alternatives, and report environmental performance will be better positioned as procurement standards tighten.
Biodiversity moves from post-approval mitigation to upfront design criterion
Earlier research by IISD and WWF argued that biodiversity protection must be integrated throughout infrastructure development, not added as an afterthought. Their analysis identified critical decision points: assessment, master planning, safeguards, procurement, financing, construction, operation, and decommissioning. Each stage presents opportunities to reduce ecological harm or restore habitats.
Procurement emerged as particularly important because it determines which environmental commitments are actually enforceable. A project might include strong biodiversity safeguards in planning documents, but if those safeguards are not written into tender specifications and contract terms, they become optional. Contractors face no penalty for ignoring them.
The nature-positive procurement project addresses this gap by providing standardized language for contract clauses, tender evaluation criteria, and performance monitoring. This makes environmental requirements legally enforceable rather than aspirational. Suppliers must demonstrate compliance to receive payment or qualify for future contracts.
This approach also recognizes that infrastructure decisions are path-dependent. Once a road alignment is chosen, changing it becomes very expensive. Similarly, once a contractor is selected based on lowest price alone, requiring additional environmental work means renegotiating the contract. Early integration of biodiversity criteria avoids these problems by baking requirements into initial decisions.
A 2025 UN commitment linked to the GRID IP program explicitly referenced nature-positive approaches in transport infrastructure, describing them as part of a paradigm shift toward safeguarding ecosystems, restoring biodiversity, and reducing greenhouse gas emissions. This signals growing international consensus that infrastructure development and nature protection must be planned together, not treated as competing priorities.
What nature-positive procurement means for transport projects
Nature-positive procurement changes how transport infrastructure projects are evaluated and delivered. Traditionally, procurement focused on cost, schedule, and technical capacity. Environmental considerations were assessed separately, often by different teams using different criteria. This created misalignment between what procurement officers prioritized and what environmental assessments recommended.
Under nature-positive procurement, biodiversity impact becomes a weighted factor in supplier selection. A contractor might submit the lowest bid but score poorly on environmental performance. Depending on how tender evaluation is structured, that could disqualify them or require them to improve their environmental offer. This forces suppliers to invest in ecological expertise and demonstrate credible environmental management systems.
Tender specifications must include clear biodiversity requirements. For example, a road construction tender might require contractors to avoid critical habitats, use wildlife crossings at specific locations, or restore degraded areas adjacent to the project. These requirements are not suggestions; they are contract obligations with defined deliverables and payment milestones.
Contract performance clauses then enforce these requirements during construction. If a contractor fails to implement agreed biodiversity measures, they face financial penalties or contract termination. This changes the risk calculation for suppliers. Environmental compliance becomes a commercial imperative, not a regulatory formality.
For project owners, nature-positive procurement reduces long-term risk. Infrastructure that damages critical habitats may face legal challenges, funding withdrawal, or reputational damage. Projects designed to minimize biodiversity harm from the outset avoid these problems. Additionally, infrastructure that protects or restores ecosystems can deliver co-benefits like flood regulation, carbon sequestration, or improved community relations.
UK businesses face tightening environmental requirements in international contracts
UK engineering firms, contractors, and consultants active in international infrastructure markets will encounter these procurement changes as they bid for development bank-funded projects. The Asian Development Bank, World Bank, and other multilateral lenders are increasingly requiring borrowers to adopt nature-positive standards. Therefore, suppliers must demonstrate environmental competence to remain competitive.
This affects tender preparation in several ways. Firms need ecological expertise on their bid teams, either in-house or through partnerships with environmental consultants. They must be able to read and interpret biodiversity assessments, propose design alternatives that reduce ecological impact, and explain how they will monitor and report environmental performance.
Tender responses will need to document environmental credentials more thoroughly. This includes evidence of previous projects where biodiversity measures were successfully implemented, staff qualifications in ecological management, and systems for tracking environmental compliance. Generic statements about commitment to sustainability will not suffice. Procurement teams will look for specific, verifiable evidence.
Contract management processes must also adapt. If a contract includes biodiversity performance clauses, project managers need systems to track compliance, report progress, and respond quickly if environmental issues arise. This requires training site staff, establishing monitoring protocols, and maintaining clear documentation.
For smaller firms without established environmental management systems, these requirements create a barrier to entry. They may need to invest in training, hire ecological specialists, or form joint ventures with firms that already have relevant experience. However, early investment in environmental capability could provide a competitive advantage as standards tighten.
UK-based environmental consultants may find new opportunities advising contractors on biodiversity compliance. As procurement standards become more demanding, contractors will need expert support to meet requirements. This could create demand for ecological surveys, habitat restoration planning, and environmental monitoring services.
Core elements of the nature-positive procurement framework
The nature-positive procurement framework includes several key components that distinguish it from traditional environmental safeguards. Understanding these elements helps businesses prepare for upcoming requirements.
- Biodiversity screening is required before site selection, ensuring projects avoid critical habitats and ecologically sensitive areas from the outset rather than attempting mitigation later.
- Tender evaluation criteria include weighted environmental performance scores, meaning suppliers must demonstrate biodiversity credentials to compete effectively, not just meet minimum compliance standards.
- Contract terms include enforceable biodiversity clauses with specific deliverables, timelines, and penalties, making environmental performance a legal obligation rather than an aspirational goal.
- Technical guidance provides procurement officers with standardized methods for evaluating biodiversity impact, reducing inconsistency and subjectivity in how environmental factors are assessed.
- Training programs build capacity among government procurement teams, ensuring environmental requirements are understood and enforced consistently across projects and jurisdictions.
- Case study documentation captures lessons from pilot projects, allowing future procurements to learn from both successes and failures in implementing nature-positive standards.
- Monitoring systems track environmental outcomes throughout project delivery, providing accountability and enabling adaptive management if biodiversity impacts exceed predictions.
Training and capacity building support consistent implementation
The success of nature-positive procurement depends on whether procurement officers understand and consistently apply new standards. IISD is developing an online training program to address this challenge. The program aims to give government procurement teams practical skills for evaluating biodiversity impacts and writing effective environmental contract clauses.
Training covers how to interpret ecological assessments, which are often highly technical documents prepared by environmental specialists. Procurement officers need to understand what findings mean for project risk, how serious different impacts are, and which mitigation measures are realistic given budget and schedule constraints. Without this knowledge, procurement teams may ignore environmental advice or accept inadequate environmental proposals from suppliers.
The program also addresses how to structure tender evaluation to reward strong environmental performance. This includes deciding how much weight to give biodiversity criteria relative to cost and schedule, defining what constitutes acceptable environmental performance, and explaining evaluation criteria clearly in tender documents so suppliers know what is expected.
Capacity building extends beyond individual training to institutional systems. Procurement agencies need processes for reviewing environmental documents, consulting ecological experts, and monitoring contract compliance. They also need clear guidance on when to reject a tender because of unacceptable biodiversity impact, even if the supplier meets cost and technical requirements.
For businesses, this training effort signals that environmental requirements will be taken more seriously. Procurement teams with better environmental knowledge will scrutinize supplier proposals more carefully and reject weak environmental commitments. Consequently, suppliers must ensure their environmental offers are credible and substantiated by evidence.
Development banks link lending to nature-positive procurement standards
Development banks play a crucial role in spreading nature-positive procurement standards. The Asian Development Bank, a key partner in the GRID IP program, funds major transport infrastructure across Asia and the Pacific. When the bank requires borrowers to adopt specific procurement standards as a condition of lending, those standards become de facto requirements for a significant portion of regional infrastructure spending.
The bank's involvement in this initiative suggests it intends to incorporate nature-positive criteria into its operational policies. This would affect how projects are appraised, what environmental studies borrowers must complete, and how tender documents are structured. Borrowers would need to demonstrate that biodiversity considerations are embedded in procurement processes, not handled through separate environmental assessments.
Other multilateral development banks are moving in similar directions. The World Bank, European Investment Bank, and regional development banks are all updating environmental and social frameworks to reflect growing concern about biodiversity loss. These updates increasingly emphasize integrating environmental considerations into project design and procurement, not treating them as separate compliance exercises.
For UK businesses, this creates both challenges and opportunities. Firms bidding on bank-funded projects will face stricter environmental requirements, requiring investment in ecological expertise and environmental management systems. However, firms that build strong environmental credentials early will be well-positioned as standards tighten across multiple banks and regions.
The standardization of requirements across development banks could also reduce complexity for suppliers. Currently, different banks have different environmental policies, making it difficult for contractors to know what is required. If banks converge on common nature-positive procurement standards, suppliers could develop consistent approaches applicable across multiple projects and jurisdictions.
How this connects to broader infrastructure and climate goals
Nature-positive procurement aligns transport infrastructure with climate and biodiversity commitments made under international agreements. The UK, like most countries, has committed to protecting biodiversity under the Convention on Biological Diversity and achieving net-zero emissions under the Paris Agreement. Infrastructure decisions directly affect both goals.
Transport infrastructure is a major source of habitat fragmentation and biodiversity loss. Roads divide ecosystems, preventing species movement and gene flow. Construction destroys or degrades habitats. Operation causes pollution, noise, and wildlife mortality. Addressing these impacts at the procurement stage is more effective than attempting restoration after damage has occurred.
Infrastructure also accounts for a significant share of global greenhouse gas emissions, both from construction materials like cement and steel, and from enabling increased transport activity. Nature-positive procurement can address climate goals by favoring designs that reduce emissions, protect carbon-rich ecosystems like forests and wetlands, and enhance natural carbon sinks through habitat restoration.
IISD's broader work on sustainable infrastructure defines it as assets that conserve natural ecosystems and biodiversity while remaining financially viable and delivering value for money across the asset life cycle. This definition explicitly links environmental performance with financial sustainability, rejecting the assumption that environmental protection necessarily increases costs.
Research supporting this view shows that nature-positive infrastructure can reduce long-term costs by avoiding legal challenges, minimizing environmental damage that requires expensive remediation, and delivering ecosystem services like flood control or water purification that would otherwise require costly engineered solutions.
For businesses, this connection between environmental performance and financial viability is important. Clients are increasingly evaluating infrastructure investments over full life cycles, not just initial capital costs. Projects that protect biodiversity and reduce emissions may have lower operating costs, face fewer regulatory risks, and maintain higher asset values over time.
Where to find detailed guidance and policy documents
The International Institute for Sustainable Development publishes research and guidance on nature-positive procurement through its infrastructure program, available at IISD's website. The organization produces technical reports, policy briefs, and case studies documenting how biodiversity can be integrated into procurement processes. These resources provide practical detail for procurement officers and suppliers implementing new standards.
WWF-US, as lead partner for the GRID IP program, publishes updates on program activities and pilot projects through WWF's website. The organization's work on infrastructure and biodiversity includes research on how transport projects impact ecosystems and how to design infrastructure that minimizes ecological harm.
The Global Environment Facility, which funds the GRID IP program, provides information about approved projects, implementation progress, and environmental outcomes at the GEF website. The facility's project database includes details on funding allocations, partner organizations, and expected results for transport infrastructure initiatives.
The Asian Development Bank publishes environmental and social safeguard policies that govern how projects must address biodiversity impacts. These policies, available through the ADB website, set minimum standards for borrowers and provide guidance on integrating environmental considerations into project design and procurement. Understanding these policies helps suppliers anticipate requirements for bank-funded projects.
UK businesses working internationally should also monitor the Department for Business and Trade's guidance on environmental standards in export markets, available at GOV.UK. As environmental requirements tighten globally, UK firms need to understand how domestic environmental capabilities translate to international market requirements.
