『Abstract
Cities consumed 84% of commercial energy in china, which indicates
cities should be the main areas for GHG emissions reduction. Our
case study of Shenyang in this paper shows how a clear inventory
analysis on GHG emissions at city level can help to identify the
major industries and societal sectors for reduction efforts so
as to facilitate low-carbon policy-making. The results showed
total carbon emission in 2007 was 57 Mt CO2
equivalents (CO2e), of which 41 Mt CO2e was in-boundary emissions and 16 Mt CO2e was out-of-boundary emissions. The energy sector
was dominant in the emission inventory, accounting for 93.1% of
total emissions. Within energy sector, emissions from energy production
industry, manufacturing and construction industry accounted for
88.4% of this sector. Our analysis showed that comparing with
geographical boundary, setting system boundary based on single
process standard could provide better information to decision
makers for carbon emission reduction. After attributing electricity
and heating consumption to final users, the resident and commercial
sector became the largest emitter, accounting for 28.5% of total
emissions. Spatial analysis of emissions showed that industrial
districts such as Shenbei and Tiexi had the large potential to
reduce their carbon emissions. Implications of results are finally
discussed.
