Carbon dioxide (CO2) has been conventionally regarded as a global problem, due to the well-known effects of fossil fuel combustion to the climate of our planet. However, this paper aims at highlighting the role of CO2 from another perspective, i.e. by considering the effects of CO2 on the health and well-being of the occupants of indoor spaces. The exposure to CO2 air concentrations > 1,000 ppm causes symptoms like headache, dizziness, sleepiness and loss of attention, which may negatively influence the learning capability and the productivity of students and workers. In this sense, schools and universities are particularly vulnerable, due to the high density of occupants in classrooms and to the importance of the role of education in training the future members of the society. In the light of this issue, the present paper will provide examples of the incorrect design of indoor environments and, meanwhile, will propose simple solutions to monitor the problem of indoor CO2 concentration and improve the indoor environmental quality of public places. © The Authors, published by EDP Sciences, 2019. ; The work was partly supported by Act 211 of the Government of the Russian Federation, contract No 02.A03.21.0006.

In this article, we will discuss about the potential of renewable energies available in a relatively small territorial context, such as municipalities, and the various problems interfering with a full exploitation of said potential. Since the launch of Covenant of Mayors, CoM, in 2008, thousands of local governments committed on volunteer basis in reaching or even exceeding, to the EU targets with regards to climate change and renewable energies for the years to come. Every local government committed to the CoM needs to produce the SEAP (Sustainable Energy Action Plan), which highlights the actions that the government is willing to implement in order to achieve the target set by the CoM (referred either to the 2020 or to the 2030). While studying the local context, many problems of various nature often arise which can be detrimental for the full exploitation of the potential of renewable resources available. This article displays a few examples of local governments located around the world and the problems encountered while writing their SEAP, related to geographical position, types of agricultural, industrial and commercial activities in the area, plants already operative, financial situation of the local government and the population living in the area. The possible areas of intervention include energy efficiency works on public and private buildings, traffic reduction strategies, energy recovery systems applied to factories and industrial plants, solar thermal, photovoltaic and wind power installations, material and energy recovery processes applied to waste management and hydroelectric power installations. © 2019 WIT Press ; ACKNOWLEDGEMENT This research was supported by the Municipality of Oppeano (Italy) and by Act 211 Government of the Russian Federation, contract № 02.A03.21.0006.
