The methodology of our greenhouse gas emission inventories from waste sector was reviewed and revised according to analyses of different methodologies and QA/QC procedures used in the 1996 IPCC Guideline, GPG 2000, and 2006 IPCC Guideline.
The waste sector of the National Inventory Report 1990-2012 was completed according to our national GHG inventory review procedure. To improve the quality of greenhouse gas emission inventories, expert consultation was inquired to assess the choice of methodology, activity data, emission factors, and other parameters needed to make the emission estimates.
The two different calculations were performed based the 1996 IPCC Guideline, and the 2006 IPCC Guideline. And the results are compared. Based on the methodology of the 1996 IPCC Guideline, 58.0% of GHG emission in the waste sector comes from the industrial wastewater treatment, 30.3% comes from municipal wastewater treatment, 7.3% comes from landfill, 2.2% comes from incineration, and 2.2% comes from compost. 77% of greenhouse gas emitted was methane, 21% was nitrous oxide, and 2% was carbon dioxide. The emission was reduced by 82% since 1990, and by 3% since 2011.
Based on the methodology of the 2006 IPCC Guideline, 44.0% of GHG emission in the waste sector comes from landfill, 29.4% comes from municipal wastewater treatment, 23.8% comes from the industrial wastewater treatment , 1.7% comes from incineration, and 1.1% comes from compost. 89% of greenhouse gas emitted was methane, 9% was nitrous oxide, and 2% was carbon dioxide. The emission was reduced by 50% since 1990, and by 5% since 2011.
