Notes on Emission Data

Emission data were compiled from various sources. It should be noted that emission factors depend greatly on the fuel characteristics, the technology/device employed in fuel combustion, as well as emission measurement. This note can only summarise some important comments to the data. Details on each data can be obtained through RWEDP's Wood Energy Database.

1. All data on default emission factor are from IPCC 1996 guidelines, in which,
   
   
   Fuelwood refers to wood/wood waste;
   Biomass includes dung and agriculture, municipal and industrial wastes;
   For Charcoal production: assuming 1 kg charcoal is produced from 6 kg wood and the energy content for wood and charcoal is 15 and 30 MJ/kg respectively. 1 TJ charcoal produced is equivalent to 3 TJ wood;
   
   
   
2. Emissions of some chemical compounds are measured or recorded in groups. In this database:
   Acids: sum of tars, phenols, and furfurals;
   NMHC: non methane hydrocarbon;
   TNMHC: total non methane hydrocarbon, per carbon molecular weight taken as 18;
   NMVOC: non methane volatile organic compounds;
   TNMOC: total non methane organic compounds;
   PIC: products of incomplete combustion;
   TSP: total suspended particulates;
