Propostas para redução de emissões de gases de efeito estufa na cidade de Ponta Grossa, baseadas em smart sustainable cities

Abstract

With the rapid growth of cities, we witness a significant increase in greenhouse gas (GHG) emissions caused by human activities. These emissions contribute to global warming, a phenomenon that, if left unchecked, will have serious environmental and socioeconomic impacts. Therefore, it is crucial to develop strategies to reduce GHG emissions in urban areas and having an effective action plan is essential in this regard. This work aims to list specific actions to reduce GHG emissions in the city of Ponta Grossa, in the state of Paraná. To achieve this objective, a bibliographical research was carried out using the Methodi Ordinatio methodology, in order to obtain greater knowledge on the subject and consolidate the best practices for reducing emissions, aiming at a future with a lower carbon impact. In addition, data on GHG emissions in Ponta Grossa were analyzed, resulting in the creation of a table that contains specific reduction proposals aligned with the needs of the city. These proposals aim to address the key emissions sectors in the city, namely energy (which represents 61% of emissions), land use change and forests (which represents 12% of emissions) and waste (which represents 4% of emissions). Considering that energy is the main source of emissions, the proposals are focused on reducing fuel consumption in Ponta Grossa, by encouraging and facilitating the use of bicycles as a means of transport, as well as the implementation of collective public transport of quality with low emission vehicles. In the waste sector, the energy use of biogas in sanitary landfills is proposed, while in the area of changes in land use, urban afforestation actions and the use of intelligent systems are proposed. The implementation of these actions in the city as a high potential for reducing GHG emissions.
