A method for decomposing urban construction carbon emission index based on material stock flow

Abstract

The application discloses a kind of urban construction carbon emission index decomposition methods based on material stock flow, it is related to urban carbon emission accounting technical field.The method includes: constructing Kaya identity, and city carbon emission is decomposed into population size, per capita building area, unit area material stock and unit material stock carbon emission intensity;City carbon emission is decomposed into city building material production stage, city construction process stage, city running stage and city building renewal demolition stage carbon emission, and Kaya identity is introduced;The carbon emission of city building material production stage, city construction process stage, city running stage and city building renewal demolition stage is decomposed into material flow, energy flow, carbon removal efficiency, direct carbon emission and indirect carbon emission, and carbon emission index decomposition is completed.Combining city construction life cycle with Kaya identity organically, multi-dimensional driving factors are identified and quantified, which avoids the limitation of only running stage carbon emission.
