Different from the traditional bottom-up approach, a combination of bottom-up and top-down methods was used to measure the Beijing high spatial resolution CO2 emission inventory. From the bottom-up approach, based on the data of nearly 13000 facilities (power station boilers, industrial kilns, heating boilers), the fossil energy consumption and carbon dioxide emissions of fixed sources were calculated. From the top-down approach, the energy consumption of boilers in different industries were verified using the energy consumption sheet by sectors, thus the systematic errors of the emission inventory were controlled at a macro level. It's found that the central urban area was still the region with the highest carbon density and intensity. To formulate a low-carbon policy for the next stage, Beijing needs to pay more attention to carbon emissions from road traffic, commercial buildings and residents' lives.

Key words: Emission inventory, Combination of bottom-up and top-down, Temporal and spatial distribution
