The human activity unequivocally influence the current warming trend of atmosphere, ocean and land. Since 1750, the Green House Gasses concentration continually increases, mainly due to the utilization of fossil fuels, reaching annual average values of 410 ppm for carbon dioxide (CO2) in the last years. For this reason, since the Kyoto protocol in 1997, the governments around the world have embarked on a path with the aim of reducing polluting emissions caused by the use of fossil sources. Some years later, with the Paris agreement, they set a goal on limiting the temperature rise well below to 2°C with respect to the preindustrial levels, improve the energy efficiency of the processes and technologies and increase the penetration of renewable energies.
