Implementing Life Cycle Carbon Emissions Standards in Urban Development

This case study by RMI examines the necessity of shifting building carbon regulations from a focus on operational emissions to a full life-cycle approach. It highlights the Meishan Near-Zero Carbon Zone in Ningbo, China, as a leading example of implementing life-cycle assessment (LCA) standards and a whole-process management mechanism to achieve deep decarbonization in urban development.

• The buildings and construction sector is a major contributor to global emissions, with construction (including materials like steel, cement, and glass) accounting for 11 percent of global carbon emissions and 6 percent of final energy use, while building operations account for 28 percent of global carbon emissions and 30 percent of global final energy use.
• Most existing building regulations focus on operational carbon, neglecting 'embodied' carbon from materials, construction, demolition, and recycling. This gap exists largely because emissions from building material production have historically been classified as industrial emissions rather than building emissions.
• Building life-cycle carbon emissions standards quantify emissions across five phases: materials production and transportation, construction, operation, demolition, and waste recycling and disposal. These standards typically use either absolute values (kgCO2/m2) or relative values based on a building emissions benchmark.
• Various regions are implementing life-cycle carbon initiatives: France launched the E+C- voluntary labeling system in November 2016; California implemented the Buy Clean California Act in July 2019, requiring Environmental Product Declarations (EPDs) for specific materials in public works; and China launched a national Standard for Building Carbon Emission Calculation in December 2019.
• The Meishan Near-Zero Carbon Zone in Ningbo, China, aims to reduce emissions by 70 percent compared to a business-as-usual scenario by 2030. To achieve a 74 percent carbon reduction in the buildings sector, Meishan is implementing an LCA standard that makes carbon reduction rates based on a reference building an obligatory target, supported by a whole-process management mechanism covering nine key points in a building's life cycle.
