Implementing Life Cycle Carbon Emissions Standards in Urban Development

The construction and operation of buildings contribute nearly 40% of global CO2 emissions, yet most regulations focus only on operational carbon. This case study highlights the Meishan Near-Zero Carbon Zone in Ningbo, China, which integrates a life-cycle assessment (LCA) standard and a whole-process management mechanism to target emissions across five phases: materials production, construction, operation, demolition, and waste recycling. The document also notes international efforts, such as France's E+C- scheme and California's Buy Clean California Act, as part of a global shift toward accounting for embodied carbon in the built environment.

• The buildings and construction sector is a major global emitter, with construction (including materials like steel, cement, and glass) accounting for 11% of global carbon emissions and 6% of final energy use, while building operations account for 28% of global carbon emissions and 30% of final energy use.
• Existing building regulations predominantly target operational carbon, often ignoring embodied carbon because the emissions from producing building materials have historically been classified as industrial rather than building emissions.
• The Meishan Near-Zero Carbon Zone in Ningbo, China, aims to reduce emissions by 70% compared to a business-as-usual scenario by 2030. To achieve a 74% carbon reduction specifically in the buildings sector, the zone is implementing an LCA standard that requires a mandatory carbon reduction rate based on a reference building.
• Meishan utilizes a whole-process management mechanism involving cross-department government collaboration to oversee nine key points in a building's life cycle, requiring contractors to submit LCA indicators for government approval.
• Other regions are adopting similar life-cycle approaches: France's E+C- scheme (launched November 2016) uses LCA for environmental performance, and California's Buy Clean California Act (July 2019) requires Environmental Product Declarations (EPDs) for specific materials like structural steel and flat glass in public works.
