Project Results

Czech Republic by ratifying UN convention on climate change (UNFCCC) promised to do each year national inventory of greenhouse gasses. One of the inventoried sectors is sector 6 Waste This work tried to precise estimation of methane from solid waste disposal sites sub sector using more sophisticated method of estimation.
Nowadays in national GHG inventory method TYG (Total Yield Gas) is used for estimation of CH4 emissions. This method is suggested for countries with poor statistical database. We applied more complex method FOD (First Order Decay) which takes in account production of GHG from waste disposed before monitored period and also takes in account other relevant factors like management of landfill, oxidation of produced methane etc. It is known that emissions estimated by TYG method are overestimated. We came to result by using FOD method that is in accordance with this fact. We created recalculated time series form 1990 to 2003 based on data about production, composition and waste management form 1970.  Result was compared with present inventory practice and tested on sensitivity to change in several parameters used for calculation. Estimation was done for years 1990-2003 mainly because of high policy relevancy of this period (to UNFCCC and Kyoto protocol). Because recalculation for entire period is complete there is negotiation with national coordinator for UNFCCC to implement results to national inventory and substitute present one (this would be done for 2004 inventory). Results also will be presented on international "WORKSHOP ON INVENTORIES AND PROJECTIONS OF GREENHOUSE GASE EMISSIONS FROM WASTE" to be held in Copenhagen, 2.-3.5.2005 where authors are send by national GHG inventory coordinator (Czech Hydrometeorological Institute) to discuss result in broader community.
