Rapidly growing economies across Asia and the Pacific face a critical infrastructure challenge: demand for energy, transport and industrial systems continues to outpace investment capacity, while climate risks, environmental degradation and social inequalities are intensifying. Closing this gap is therefore not simply a matter of building more infrastructure, but of building better—through resilient, inclusive and low-emission systems that support long-term economic transformation and societal well-being. High-quality infrastructure underpins productivity, connectivity and competitiveness, and plays a central role in enabling countries to pursue development pathways that are compatible with climate objectives and broader sustainability goals.
