The global landscape of transportation is on the cusp of an unprecedented expansion, with trillions of dollars in investment set to reshape how people and goods move across the planet over the next three decades. However, this massive build-out of roads, railways, and ports carries significant ecological risks that traditional planning and financial models have historically failed to address. In response to this challenge, the International Institute for Sustainable Development (IISD), in collaboration with WWF-US and a network of strategic partners, has announced a major initiative to develop new approaches for embedding nature-positive principles directly into the procurement processes of transport infrastructure.
The scale of the projected infrastructure boom is staggering. Current estimates suggest that by 2050, the world will see the construction of up to 4.7 million kilometers of new roads. Simultaneously, the global footprint of port areas is anticipated to quadruple. These developments are often framed as essential drivers of economic growth, providing the critical regional links necessary for trade, mobility, and poverty reduction. Yet, without a fundamental shift in how these projects are bought and built, this expansion threatens to accelerate habitat loss and deepen the isolation of wildlife populations, further destabilizing the ecosystems that support human life.
The core of the issue lies in the "how" of infrastructure development. Governments and development banks are the primary engines behind these massive projects, investing billions of dollars annually. Data from the World Bank underscores the central role of the public sector in this arena, revealing that in 2017, more than 80% of all investments in railways and roads were sponsored by public bodies and state-owned enterprises. This statistic highlights a critical lever for change: because the vast majority of these investments are channeled through public procurement processes, the rules and criteria set by government agencies and state-owned entities dictate the environmental standards for the entire industry.
Despite the significant influence of procurement, the IISD and its partners have identified a systemic gap. Current procurement processes are largely unoptimized to reduce impacts on biodiversity or to encourage the implementation of nature-based solutions. Traditionally, infrastructure procurement has been dominated by a focus on minimizing upfront capital costs and adhering to strict engineering timelines. While these factors are important, they often overlook the long-term ecological costs and the potential benefits of integrating natural elements into infrastructure design. By the time a project reaches the construction phase, the most significant opportunities to protect or enhance biodiversity have often already been lost.
To combat this systemic failure, the IISD is leading a project to build a comprehensive evidence base for nature-positive transport infrastructure procurement. The goal is to move beyond abstract environmental goals and provide a concrete blueprint for integrating biodiversity considerations across the entire procurement life cycle. This life cycle spans from the earliest stages of strategic planning and project preparation to the bidding process, contract management, and the eventual operation and maintenance of the asset.
The concept of "nature-positive" infrastructure represents a paradigm shift in the construction industry. Rather than simply aiming to "do no harm" or mitigate the most egregious environmental damages, a nature-positive approach seeks to ensure that infrastructure projects contribute to the restoration and enhancement of ecosystems. In the context of transport, this could involve designing road networks that preserve migratory corridors, utilizing nature-based solutions like restored wetlands to manage drainage and prevent erosion, or selecting port locations that minimize the disruption of sensitive marine habitats.
The IISD project is designed to provide the practical tools necessary to turn these principles into reality. A key output of the initiative will be a technical handbook tailored for procurement practitioners. This handbook will serve as a guide for government officials and project managers, offering clear methodologies on how to include biodiversity criteria in tender documents and how to evaluate bids based on their environmental performance. By providing these decision-makers with the technical language and frameworks they need, the project aims to lower the barriers to adopting sustainable practices.
In addition to the technical handbook, the project will produce a series of case studies. These real-world examples will highlight where nature-positive approaches have already been successfully implemented or where traditional procurement failed to protect vital ecosystems. These case studies are intended to demonstrate the feasibility and the value proposition of nature-positive infrastructure, showing that it is possible to build modern transport links while simultaneously protecting the environment.
Education and capacity building are also central components of the initiative. The IISD and its partners are developing an online training programme specifically designed for procurement practitioners. This program will help professionals in the field understand the complexities of biodiversity integration and equip them with the skills to manage projects that meet both transport needs and environmental standards. By fostering a global community of practice, the project seeks to ensure that the knowledge generated is shared across borders and applied in diverse geographical contexts.
The urgency of this work is underscored by the dual crises of climate change and biodiversity loss. Infrastructure is a permanent fixture on the landscape; a road built today will influence the local environment for decades. If that road is designed without regard for wildlife movement, it can permanently fragment a habitat, leading to the isolation of species and a reduction in genetic diversity. However, if the procurement process requires the inclusion of wildlife crossings or the preservation of natural buffers, that same road can be part of a landscape that remains ecologically functional.
Furthermore, the integration of nature-based solutions into transport infrastructure can enhance the resilience of the assets themselves. Natural features such as mangroves, forests, and wetlands can provide protection against extreme weather events, such as flooding and storm surges, which are becoming more frequent and intense due to climate change. When procurement processes prioritize these natural defenses, they not only protect biodiversity but also safeguard the financial investment and the safety of the people who use the infrastructure.
The collaboration between the IISD and WWF-US brings together expertise in international policy, sustainable finance, and conservation science. By working with a broad range of partners, including development banks and government agencies, the project aims to influence the standards that govern global infrastructure spending. The involvement of development banks is particularly crucial, as these institutions often set the benchmark for procurement practices in emerging economies, where much of the projected 4.7 million kilometers of new roads will be constructed.
As the global community looks toward 2050, the challenge is to reconcile the need for increased connectivity with the imperative to protect the natural world. The work being led by the IISD suggests that the solution lies in the fine print of procurement contracts and the technical criteria of government tenders. By embedding nature-positive principles into the very DNA of how infrastructure is bought, it is possible to ensure that the transport networks of the future support both a thriving economy and a healthy planet.
The development of this evidence base, the technical handbook, and the training resources marks a significant step forward in aligning global infrastructure development with environmental sustainability. As these tools are rolled out to practitioners around the world, the focus will remain on transforming procurement from a bureaucratic hurdle into a powerful engine for ecological restoration. Through this initiative, the IISD and its partners are providing the roadmap for a future where transport infrastructure and nature can coexist and flourish together.
