Introduction

In an era defined by environmental consciousness and the imperative for sustainable development, Life Cycle Assessment (LCA) has emerged as a powerful and indispensable tool for evaluating the true environmental footprint of Road Infrastructure Projects. Moving beyond traditional assessments that focus solely on construction, LCA provides a holistic, cradle-to-grave analysis, quantifying environmental impacts across all stages, from raw material extraction and manufacturing to construction, operation, maintenance, and end-of-life disposal or recycling. This training course is meticulously designed to equip civil engineers, environmental consultants, sustainability managers, infrastructure planners, policy makers, and researchers with cutting-edge knowledge and practical skills in understanding LCA methodology (ISO 14040/44), defining study scope and boundaries for road projects, collecting and managing relevant inventory data, performing impact assessment calculations, interpreting results for decision-making, and utilizing LCA software tools for comprehensive environmental evaluation. Participants will gain a comprehensive understanding of how to apply LCA to identify environmental hotspots, compare design alternatives, inform material selection, and drive the development of truly sustainable and resource-efficient road networks.
