The energy sector has the greatest contribution to these phenomena in terms of greenhouse gases emissions. The paper proposes an application in the energy sector for assessing CO2 emissions resulted from burning classic solid fuels and alternative and biomass fuels at a Combined Heat and Power (CHP) using two methods, either by calculations based upon data obtained from analytical laboratory investigations or by direct measurement at the source. The investigations were carried out to highlight the influence of the addition of biomass (sawdust) to conventional solid fuel (lignite) for reducing CO2 emissions, recovering unburned carbon content present in the slag, improving the lignite energy properties, in order to use the biomass and slag waste and reduce the CO2 emissions.en-USEnergy sectorCoalsBiomassWasteCarbonCO2 emissionArticle000356637100009
