Urban Efficiency II: Seven Innovative City Programmes for Existing Building Energy Efficiency builds on research in the successful predecessor “Urban Efficiency” Report and captures seven new detailed city case studies from C40 member cities. It is primarily targeted at city-level policy makers and decision makers across the world. The report increases the resource and evidence base available to support cities understanding of the characteristics and impact of innovative city programmes emerging across C40 cities, that advance operational energy efficiency and retrofitting in existing, privately owned buildings.

Tokyo's Carbon Reduction Reporting for Small and Medium Entities – Abstract

The Carbon Reduction Reporting for Small and Medium Entities (CRR) mandates the annual reporting of CO2 emissions for existing small and medium-sized facilities (i.e. single building or group of buildings) in the Tokyo metropolitan. These facilities comprise some 60% of total CO2 emissions in Tokyo’s industrial and commercial sectors. In addition to the mandatory component, CRR has succeeded in attracting a large number of voluntary submissions from facilities keen to monitor annual emissions and compare to industry benchmarks.

Key Impact
Public disclosure of CO2 emissions data, and not energy consumption amounts, has enabled the scheme to attract many rms which would have been otherwise wary of publically disclosing raw energy consumption data
Emissions Reduction
13.3% CO2 reduction achieved for the period 2010 to 2014 for 23,786 facilities
