Greenhouse Gases Inventory of Energy Sector of Iran in Year 2000

Energy sector is the most important and the main sector in preparation greenhouse gases inventory of Iran. In order to calculating greenhouse gases emission of energy sector for national report of greenhouse gases inventory (based on IPCC 1996 Guideline), Tier 1 method using the software have been applied. According this guideline and the relevant software, energy sector is divided to Fuel Combustion and Fugitive Emission. In Fuel Combustion sector, fuel consumption has been compiled for different sub- sectors. Calculated greenhouse gases emission in greenhouse gases inventory for year 2000 are as follow: CO2, CH4, NOx, CO, NMVOCs and SO2. It is necessary to mention that fuel consumption in Iran have been compiled for months of year 1379 (solar year). National emission factors have been used for some fuels and sectors, which has been available. According to calculations and results of software, CO2 emission from all energy sectors in year 2000 has been estimated about 315298 Giga grams. In comparison of CO2 emission in year 2000 and year 1994 (285891.33 Gg) shows a growth about 10%. Emissions of CH4, N2O, CO, NMVOCs and NOx have been respectively estimated 79, 8, 3308, 1144 and 586 Giga tone. Also,CH4 and SO2 emissions from fugitive emission have respectively been estimated about 1723 and 39 Giga grams
