Net Zero Carbon Frameworks

FRAMEWORK TOWARDS NET ZERO CARBON TRANSITION

Problem Statement
Climate Emergency

Net Zero Whole Life Carbon Stages [A1-D]
Considers net zero whole life carbon, moving towards a circular economy that seeks to maintain value and utility from assets, materials and resources posing challenges of data collection and as-built verification of impacts.This would require close collaboration within the supply chain, annual reporting and offsetting of embodied carbon associated with operation, maintenance, repair and refurbishment of buildings as well as developing end-of-life scenarios.

Net Zero Embodied Carbon Stages [A1-A5]
Embodied carbon is usually used as shorthand for the Global Warming Potential impacts associated with sourcing and extracting building materials, manufacturing, construction, demolition, maintenance and end-of-life processes.

Net Zero Operational Carbon Stage [B6]
For net zero operational carbon a building’s total annual net CO2e emissions should equal zero. Closing the ‘performance gap’ where modelled building energy performance does not equate to actual in-use performance, the aim is to achieve net zero carbon for operational energy with appropriate usage.

Beyond LCA
Circular economy replaces the linear economy and is achieved through the application of principles: maintain, repair, reuse, re-manufacture and recycle, as well as leasing and servicing.
