A Life Cycle Thinking Framework to Mitigate the Environmental Impact of Building Materials

摘要: Summary Urbanization and population growth have contributed to a tripling of building material consumption from 2000 2017. Building materials range environmental impacts throughout their life cycle, extraction, processing, transport raw construction, use, eventual demolition waste. Mitigation measures that target specific or value chain stages may therefore incremental even adverse net effects. In this perspective, we develop framework for applying cycle thinking identify key corresponding mitigation approaches, inform design selection, ensure effective treatment recycling construction wastes. Life evaluation can also be used assess avoid trade-offs among stages. Challenges implementing these principles include collecting integrating inventory data products, managing multiple stakeholders within the industry, monitoring end-of-life impacts; overcoming such challenges are discussed.
