	Articol:	CONSIDERATIONS RELATING TO MONITORING OF GREENHOUSE GAS EMISSIONS IN MARAMURES COUNTY. Autori: IRINA SMICAL, MIRELA COMAN, SERBAN-NICOLAE VLAD, VASILE OROS, DAN COSTIN.


	Rezumat: The paper refers to issues related to evolution of greenhouse gas emissions in Maramures County, in the context of their monitoring as part of the National Inventory of Greenhouse Gas Emissions. These gases represented by carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF₆) constitute the leading cause of global warming and hydro-meteorological changes attracting the major concern of scientists around the world. The biggest impact generated by the human activities is due to CO₂ and NH₄ emissions which are responsible for increasing with 50% in GHG concentrations in the atmosphere. In Maramures County the largest GHG emissions result from industry and traffic. The most contribution in CO₂ equivalent is due to CO₂ emissions (52.4%) and NH₄ (45.5%). The monitoring of GHG emissions in Maramures County has been done using the CORINAIR methodology. Romania is included in Annex B of the Kyoto Protocol and has committed to reduce the greenhouse gas emissions by 8% between 2008-2012, compared to1989. The increasing by 0.74ºC of global average temperature in the last century and its gradual trend triggered a high interest in this area not only of scientific but also political viewpoint. Key words: greenhouse gases, climate changes, CO₂ equivalent, GWP
