In this context, this sector contributes significantly to greenhouse gas (GHG) emissions, intensifying the impacts of climate change. Given the above, the objective of this study was to evaluate GHG emissions from the final disposal of MSW in the state of Pará, considering the different types of disposal adopted by municipalities, as well as to propose mitigation measures aimed at promoting sustainable and resilient cities. The data used were secondary, extracted from the National Sanitation Information System (SNIS) for the year 2022, currently integrated into the National Sanitation Information System (SINISA); and from public agencies, which allowed us to determine the state's situation regarding final disposal, the mass of MSW collected, and reuse initiatives. In addition, CH₄ and CO₂e emissions were estimated based on standardized emission factors, considering the types of final waste disposal, which enabled an analysis by integration region. Finally, mitigation measures were proposed, divided into five strategic areas: legal, managerial, operational, infrastructure, and education for sustainability. The results showed that the state of Pará is marked by a predominance of environmentally inappropriate practices, since 86.11% of municipalities still send their waste to dumps and 9.72% use controlled landfills. Only 18 of the 144 municipalities analyzed have solid waste recovery initiatives. Thus, considering that in 2022 the total amount of MSW collected was 2,364,086.98 tons, the estimated GHG emissions for that same year were 990,668,182.3 tons of CO₂e. The integration regions that emitted the most GHGs were Guajará, Rio Capim, Baixo Amazonas, and Guamá, characterizing a significant inequality between the state's Integration Regions, reflecting socioeconomic disparities, infrastructure limitations, and different levels of technical and administrative capacity in the municipalities. The proposals presented highlight the need to strengthen environmental governance, expand enforcement, encourage intermunicipal cooperation, invest in adequate infrastructure, and take continuous action on environmental education and the eradication of dumps. Thus, a systemic and integrated approach that promotes the circular economy, socio-environmental justice, and sustainability is recommended. Therefore, the results obtained by the research contribute as technical support for environmental planning and the formulation of public policies aligned with the National Solid Waste Policy and climate goals.Acesso AbertoGestão de resíduos sólidosMudanças climáticasPlanejamento ambientalRegião amazônicaSolid waste managementClimate changeEnvironmental planningAmazon regionCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA::SANEAMENTO BASICO::RESIDUOS SOLIDOS, DOMESTICOS E INDUSTRIAISCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::METEOROLOGIA::CLIMATOLOGIATrabalho de Curso - Graduação - Monografia
