Differences with IPCC methods: IPPU sector
For IPPU sector emissions of SLCFs, most methods have been consistent with IPCC
methods, i.e. based on activity level (AD); Usually the product yield) multiplied by theEF. In addition, solid waste combustion is not included in the IPCC system

Applicability: Different SLCFs emission inventories
Many environmental protection departments or institutions have developed
some SLCFs emission inventory system, which are often applicable todifferent regions
Such as:

UNEP : UNEP Atmospheric Brown Clouds Emission Inventory
EMEP: EMEP/EEA Air Pollutant Emission InventoryAP-42: AP-42 emission inventory factor system
MEE: Technical guide for compilation of emission inventory from Ministry ofecology and Environment of the People's Republic of China13

Applicability: MEE(MEP)
MEP issued a series of technical guidelines for compilation of the emission inventory toguide the construction of emission inventory in China.

Applicability: MEP

MEP issued a series of technical guidelines for compilation of the emission
inventory to guide the construction of emission inventory in China.
 Applicability: The system is mainly established according to China'scharacteristics and adopts China's local emission factors and emission
departments to the greatest extent. Therefore, it is suitable for theconstruction of inventory in China.
 Compared withthe IPCC

Tier1

method: The difference of theconstruction method is mainly reflected in the transportation sector,
which is calculated based on the vehicle millage rather than the fuleconsumption.

Gaps and advices
As mentioned above, compared with IPCC's greenhouse gas emission
inventory construction system, emission inventory construction of SLCFs
often considers more sectors and methods.
 Sectors: SLCFs emission estimation often needs to consider morecomprehensive sectoral emissions, such as solid waste incineration,ordnance detonation, biomass combustion and solvent use processemissions (mainly VOCs).
 Methods: Compared with IPCC system, in addition to the calculation basedon vehicle mileage of road transportation mentioned before, more andmore energy departments (especially factories and enterprises) havedeveloped real-time calculation methods for on-line monitoring, which isworthy of further exploration.
