This article discusses bottom-up inventory analysis for greenhouse gas (GHG) emissions from fossil fuels extraction and processing in Poland. The approaches to modelling geo-referenced cadastres of emissions from fossil fuels extraction and processing are described as well as methods of uncertainty reduction using the knowledge on spatial greenhouse gas emissions distribution. The results of GHG emissions spatial inventory contain the information on geographical coordinates of emission sources. This information is useful for indication the largest emission sources. In this article we present the obtained results on spatial GHG inventory from fossil fuels extraction and processing in Poland, based on IPCC guidelines taking into account locations of emissions sources, official statistics and digital maps of territories investigated. Monte-Carlo method was applied for a detailed estimation of GHG emissions and results uncertainty in the main categories of analyzed sector.
