MORA, Pedro; GIL, Esther; SANCHEZ-MARTIN, Laura  e  LLAMAS, Bernardo. EVOLUTION OF EMISSION FACTORS AS AN ENVIRONMENTAL IMPROVEMENT TOOL. CASE STUDY OF THE SPANISH CEMENT SECTOR. Rev. Int. Contam. Ambient [online]. 2021, vol.37, 53991.  Epub 06-Jun-2022. ISSN 0188-4999.  https://doi.org/10.20937/rica.53991.

Environmental issues relevant to the Spanish cement sector, together with the regulation of emissions which are harmful to health, safety and the environment, have led to the development of emission factors as a standardization tool at sector level. According to these factors it is possible to establish their evolution and analyze the technical causes that influence the behavior of polluting emissions. This research includes this evolution in a historical series encompassing the period 2009-2018. The statistical analysis developed makes it possible to establish emission factors for the cement sector in a robust and reliable way. The results include the evolution of emissions as well as the latest values taken from an entire industrial sector in Spain. The evolution of emission factors shows an increasing awareness towards the reduction of polluting gases, validating the emission factors tool and its methodology.

Palavras-chave : environmental protection; cement manufacture; emissions factor.
