We are experiencing the hottest period since the last glaciation. Thus, this article aimed to describe actions taken by the Secretariat of Agriculture and Environment (SAMA) aiming at reducing and sequestering the gases that cause the greenhouse effect - GHG in the city of Itapira-SP. For this, a data survey was carried out at SAMA in the municipality and other departments, responsible for carrying out the actions. The results showed that the topic is little debated and studied in the municipalities of Brazil and the activities developed in this study characterize plausible actions with regard to raising awareness of public power and civil society regarding the mitigating actions related to these gases, as well as the benefits their execution, serving as a link of participation in the construction of sustainable cities. Keywords: Greenhouse effect, Global warming, Carbon Hijacking, Itapira-SP. 1 INTRODUCTION As man increases his ability to intervene in the environment by extracting and modifying natural resources for his needs, numerous conflicts occur regarding the use of the environment (MARTELLI et al., 2018). In recent centuries, a model of civilization has imposed itself, bringing industrialization, with its form of production and organization of work, besides agricultural mechanization, channeling of water bodies, intensive use of agrochemicals, occupation of protected areas and growing urbanization, with a process of population concentration in cities (MARTELLI, 2015). Oliveira Jr. and Sousa (2012) portray that water and atmosphere polution, deforestation, incorrect land use, degradation of water resources among others, characterize aggravating environmental problems in the contemporary world and stimulate the awareness of society to take immediate action, giving 11 South Florida Journal of Development, Miami, v.1, n.1, 11-20, jan./mar. 2020. ISSN 2675-5459 priority to the conservation of resources essential to the preservation of the planet and quality of life of people, especially those living in large urban centers. As countries intensified their unbridled search for industrialization and economic development, several manifestations of the environmental crisis with degradation of the natural environment due to anthropic actions began to emerge frequently (SILVA, 2015; MARTELLI et al., 2013). With this anthropic intervention in the natural environment and intense industrialization, another problem has been occurring, the release of greenhouse gases in the atmosphere (GEE). According to Braga et al. (2001), since the industrial revolution, air pollution has grown and become a serious problem for cities, especially the industrialized ones, adding to the pollution caused by industries, cars and forest fires. These gases have favored changes in the climate affecting everyone directly and indirectly. These changes are consequences of the increase in the concentration of gases such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), some chlorofluorocarbons (CFC), among others (NUNNENKAMP, CORTE, 2017). According to Martelli et al. (2013), this environmental crisis that the planet is going through, and the consequences to which we are subject, have mobilized various sectors of society such as civil authorities, governmental and non-governmental institutions. This worldwide concern with the environment has motivated several international, regional and local meetings, aiming at the discussion and elaboration of proposals for solutions to the subject. It is notorious that environmental problems influence states and towns to think about public policies or action plans, with a view to re-educate societies in order to stimulate continuous processes that enable alternatives for the conservation, recovery and improvement of this environment (CUNHA, 2018). In this sense, over the last few years, the Department of Agriculture and Environment of Itapira- SP (SAMA) has been developing several activities aiming at the reduction of the emission and/or the neutralization of GHG. In this regard, this article aimed to describe the actions carried out by SAMA and other related departments of the municipality in 2019 and 2020 aiming the mitigation of GHG in the city of Itapira-SP, gases that have been favoring the increase of the world temperature and thereby serving as a model for other municipalities in Brazil and the world. 2 MATERIAL e METHODES Characterization of the City of Itapira The Municipality of Itapira is part of the Administrative Region of Campinas and is located in the Southeast region, central-eastern portion of the State of São Paulo, at 22°26'10" latitude S and 46°49'18" longitude W, approximately 63 km distant (via the bypass ring) from the city of Campinas and 159 km from the state capital. 12 11 South Florida Journal of Development, Miami, v.1, n.1, 11-20, jan./mar. 2020. ISSN 2675-5459 It has an area of 518,416 km², with an estimated population of 73,844 inhabitants. The urban perimeter has an area of 58,042 m² with a population density of 132.21 inhabitants per km² (IBGE, 2020). Survey of GHG reduction and hijacking actions The activities aimed at and reduction and/or kidnapping of GHGs in the municipality of Itapira-SP are carried out by SAMA, in conjunction or not with other municipal departments. In view of this positioning, an exploratory analysis of data in the archives of the respective secretariat was carried out regarding the activities carried out in 2019 and 2020 with respect to GHGs. After survey, the data were recorded in a spreadsheet formulated by the authors, and later the data were tabulated for presentation. 3 RESULTS E DISCUSSION Among the numerous activities developed by SAMA, which will be reported throughout this article, the survey of the municipal diesel-powered fleet was initially portrayed. The dark smoke emitted from the exhaust of diesel vehicles is a sign of engine adjustment problems. The darker the color of the smoke, the higher the consumption of the vehicle and the amount of particulate emitted into the atmosphere. The color of the black smoke indicates that the diesel is not being fully burned and may cause damage to the engine and its components such as pumps, nozzles and turbines, favoring environmental impacts such as increased release of GHG. According to Carvalho (2011), diesel powered vehicles emit more CO2 per unit of volume or weight of fuel than other motorized modes. In this work, the author used an average emission factor of 2.6 kg of CO2 for each liter of diesel burned in combustion, which together with the average value of 0.5 kg of CO2 emitted to produce and distribute the fuel reached a final emission rate of around 3.2 kg of CO2/l of diesel. Therefore, governed by Municipal Law no. 4,519/09, which provides for activities related to air pollution control, SAMA performs two annual monitoring - first and second semesters Figure 1A of the municipal diesel-powered fleet in order to verify the vehicles that due to mechanical problems are releasing smoke with a dark tonality. For this measurement an instrument authorised by the Cetesb State agency called the Ringelmann Scale is used. Vehicles with shades above the permitted level are issued an opinion to remedy the problem and the inspected vehicles receive a seal of inspection with the date and result of the analysis. This action is of fundamental importance with regard to GHG mitigation measures and can be adopted by other municipalities. 13 South Florida Journal of Development, Miami, v.1, n.1, 11-20, jan./mar. 2020.

Continuing the activities, it was verified that the city of Itapira encourages alternative transportation, presenting a bicycle path network. Currently, the city has an extension of approximately 5,180m between bicycle path and cycle path, connecting important neighborhoods of the city. With the large fleet of cars on the streets, the data shows that traffic in cities grows every day and with it the emission of tons of CO2 and other gases in the atmosphere and it is not necessary to cite examples from the big capitals, because in peak times the traffic is well compromised in the access roads in the central area of Itapira and the bicycle becomes an alternative and ecologically sustainable transport with advances in the environmental aspect, health and quality of life of the population. Figure 2: In A, bicycle path on Italos avenue interconnecting important points of the municipality; B, bicycle stand in strategic places favoring the practice of this transportation. The creation of a bicycle path plan by the municipalities is part of the strategies to change the paradigm in the production of our cities, through the repricing of urban space distribution, giving priority to non-motorised and more affordable transport alternatives. 14 South Florida Journal of Development, Miami, v.1, n.1, 11-20, jan./mar. 2020.
