The emission factor and emission inventory of NOX for the household activity are developed taking into consideration local characteristic of the household in Thailand. Activities data in this study are collected in Rayong province. These data will serve and assist in developing the emission database under the Pollutant Release and Transfer Registration (PRTR) program. Emission factors of NOx, based on amount of LPG usage per household per year are calculated for different size of household. These values are 142.2, 213.3 and 426.6 kg of NOx /1000 household/year for small, medium and large sizes of household, respectively. It is estimated that the total amount of NOx emissions from household's LPG cooking will be about 60.31 tons per year in Rayong province. © (2014) Trans Tech Publications, Switzerland.Mahidol UniversityEngineeringConference PaperSCOPUS10.4028/www.scientific.net/AMR.931-932.655
