A new proposal for environmental accounting of Japanese municipality with the framework of endpoint-type lcia method "lime2": Calculation of environmental conservation effects in yokohama city from 2000 to 2015

With a focus on Japanese municipalities, this study proposes a unified methodology based on the endpoint-type LCIA method LIME2 for calculating the effects of environmental conservation, which is one item used by administrative divisions in Japan for environmental accounting. The proposed methodology integrates the assessment theory of LIME2 with the basic tenets of the Environmental Accounting Guidelines 2005, and furthermore contributes unique ideas on interpreting the assessment results. When the methodology was applied to the city of Yokohama, the environmental conservation effect for the 15-year period from 2000 to 2015 was calculated in monetary terms as -1.07 billion yen.
