The Infrastructure Decisions Shaping Climate’s Future
A new report makes the case that infrastructure strategy is now central to climate strategy, and outlines what's needed to build for a low-carbon future.
Infrastructure has quietly become the single largest driver of global emissions, accounting for 79% of greenhouse gases worldwide. As governments race to close the infrastructure gap and meet growing demand across energy, transport, water, waste, digital, and buildings, the way these assets are planned, built, and managed is increasingly determining whether net-zero targets remain within reach.
A new report from the UN Environment Programme and the University of Oxford makes the case plainly: infrastructure can no longer be treated as a series of disconnected, sector-by-sector investments. What's needed is a more integrated approach, one that embeds climate resilience and decarbonization into national planning from the start, rather than adding it in afterward.
The stakes are rising on both fronts. Assets built without climate considerations risk becoming liabilities as conditions shift and capital increasingly flows toward resilient, transition-aligned projects. At the same time, infrastructure that's designed with adaptation and mitigation in mind is positioned to support long-term economic stability, protect biodiversity, and reduce exposure to future climate shocks.
Closing the infrastructure gap and building climate-compatible systems are no longer separate goals, they're converging into a single challenge. Governments and investors are increasingly focused on how infrastructure gets built. Every stage of an asset's life, from initial design through to decommissioning, carries choices that accumulate - shaping resilience, emissions and value for years to come.
As national governments look to translate global targets into local projects, the infrastructure decisions made in the next few years will set the trajectory for climate outcomes for generations ahead.
