T/XJBX 0083-2025 Assessment Specification for Life Cycle Carbon Emissions of Low-Carbon Concrete
Basic Information
Scope
With the increasing urgency of global efforts to combat climate change and promote sustainable development, the construction industry, as a major sector of energy consumption and carbon emissions, is facing significant pressure to transition to low-carbon practices. Concrete, as the most widely used building material in the world, generates carbon emissions throughout its entire life cycle, including raw material production, transportation, construction, use, and demolition, which has a significant impact on total greenhouse gas emissions. Conducting a full life-cycle carbon emissions assessment of concrete is an important supporting measure for promoting the research and development of low-carbon building materials, the promotion of green buildings, and the achievement of carbon peaking and carbon neutrality goals. At present, an internationally well-developed Life Cycle Assessment (LCA) methodology system has been established. China has also successively issued relevant standard documents on carbon emissions accounting, carbon footprints of building materials, and green building evaluation. However, for concrete, a material with complex composition, widespread application, and significant regional differences, existing methods still have shortcomings in data acquisition, boundary definition, result comparison, and application guidance, making it urgent to develop a unified, standardized, and highly operable assessment methodology. This document aims to provide a systematic specification for the full life-cycle carbon emissions assessment of low-carbon concrete, clarifying the assessment boundaries, methods, indicators, and result expression methods, and promoting carbon emission reduction and green transformation across the entire concrete industry chain. This document is applicable to the carbon emissions assessment and management of low-carbon concrete products in all stages of R&D, design, production, construction, operation, and recycling, and can also provi
