Item Avaliação de emissões de gases de efeito estufa no CEASA/PE(2024-07-24) Soares, Guilherme Bastos; Pragana, Rossanna Barbosa; http://lattes.cnpq.br/8705453663044944; http://lattes.cnpq.br/7776540361160364Greenhouse gas (GHG) emissions have always occurred naturally on Earth, but global concern about anthropogenic emissions began in 1979, with the holding of the first world climate conference. After that, several agreements were created with the aim of reducing emissions of these gases, such as Eco-92, the Kyoto Protocol and the Paris agreement, which established goals for reducing GHG emissions. Accounting for these gases is a way of quantifying emissions from activities carried out in a company or organization, therefore, the study aimed to map the activities carried out at CEASA/PE, seeking methods to quantify the emissions generated, such as through the calculation of the GHG Protocol, which condenses the emission factors calculated for each process according to the year in which the emissions will be recorded. For the calculations of emissions avoided in the composting process, the AMS-III.F tool was used, making a comparison with emissions arising from the waste landfilling process. With the calculations carried out, it was possible to observe that CEASA had a total of 13.481,24 tons of CO2-eq emitted in the year 2023, with the composting process at CEASA-PE avoiding the emission of 8,108 tCO2-eq, when compared to landfilling. of the same waste. Furthermore, it is observed that if all organic waste were composted by the center, the avoided emissions could reach up to 22,656.9 tCO2-eq, demonstrating the potential of composting to reduce GHG emissions. Furthermore, the study notes that composting is an important contributor to the reduction of GHG emissions, requiring the implementation of broader and more controlled composting processes. It is recommended that there be more studies related to the transport of waste to optimize the effectiveness in reducing composting projects.Item Política Estadual de Mudanças Climáticas: instrumentos, resultados e interação com questões florestais(2022-10-10) Caetano, Matheus Braga Cordeiro; Meunier, Isabelle Maria Jacqueline; http://lattes.cnpq.br/9202793669201466; http://lattes.cnpq.br/4973571977743177The climate changes that the planet has been facing are the result of the intensification of the so-called greenhouse effect. In this sense, countries have signed agreements, establishing measures that those involved must adopt to define mitigation and adaptation strategies. Forests play an important role in mitigation, as they act as atmospheric carbon sinks, and it is essential that conservation strategies and expansion of forested areas are settled. Brazil and its states have been developing their national and local coping strategies. This work aims at describing public policies on climate change in the state of Pernambuco, in order to identify the main legal frameworks that provide the basis for confronting climate change in the region. Moreover, this paper analyzes the points of interaction of climate policies and measures for conservation and reforestation, identifying their results and stages of implementation and which projects have been executed or are in progress linked to the forest area that contribute to mitigating the effects of climate change. Qualitative research was developed based on bibliographic research, official documents and interviews. The state of Pernambuco has its state climate policy and instruments such as the State Plan for Climate Change (PEMC/PE) and the Pernambuco Decarbonization State Plan (PDPE) in addition to other policies that have programmatic coherence. It was identified that, for the forestry sector, the plans establish goals aimed at conservation and reforestation. Of the objectives for the forestry sector of the PEMC/PE, only the expansion of 22 conservation units could be verified. Mechanisms such as Payment for Environmental Services (PSA) and Reduction of Emissions from Deforestation and Degradation (REDD), proposed as options for the sector, were not proven successful, with no projects being developed over the twelve years of climate policy due to the lack of financial support for project development. There are only two programs under development in Pernambuco that can contribute to the mitigation strategy, but they are still in the implementation phase. The absence of implementation verification mechanisms, lack of financial support for policy implementation and low institutional coordination constitute major barriers to advancing climate policy and to mitigation by conservation and reforestation.
