The infrastructure sector plays a crucial role in the global economy, encompassing a wide array of activities from constructing buildings to maintaining critical structures. However, this sector is also a significant contributor to greenhouse gas emissions, particularly carbon dioxide (CO2), due to its energy intensive processes and materials1. As the urgency of addressing climate change becomes increasingly apparent, decarbonising the infrastructure sector is imperative. This article aims to examine the current emission levels in the infrastructure sector and explores various technological interventions aimed at reducing these emissions. The focus is on both construction and operational phases, highlighting innovations in materials, energy efficiency and renewable energy integration.
