Abstract(s)
O turismo de cruzeiros é um setor turístico que combina lazer, desporto, educação e outros serviços. Desde os anos 60, tornou-se um setor relevante para a economia global, impulsionando o turismo e o consumo local. Contudo, os impactos ambientais são significativos, com elevadas emissões de poluentes atmosféricos e gases de efeito estufa (GEE), afetando a qualidade do ar e contribuindo para o aquecimento global. Desta forma, este trabalho pretendeu identificar e avaliar o impacte destes navios na qualidade do ar da cidade de Lisboa. Este trabalho foi desenvolvido na Administração do Porto de Lisboa (APL), que possibilitou recolher dados de diversas fontes. Foram realizadas inspeções em navios de cruzeiro para identificar características gerais, consumo de combustível, uso de scrubbers, gestão de resíduos e as próprias emissões. Foram utilizados também relatórios da empresa SondarLab que contemplaram informações meteorológicas e medições horárias de poluentes em estações próximas ao porto. Outras fontes incluíram a plataforma Janela Única Logística (JUL), que forneceu dados técnicos sobre os navios, a Vessel Traffic Services (VTS), que registou horários estratégicos da movimentação destes navios e uma estação meteorológica complementar. O tratamento estatístico avaliou a representatividade da amostra, enquanto o modelo de pluma Gaussiana, parametrizado no Excel, permitiu prever e quantificar o impacto das emissões. Os resultados foram comparados com os dados reais, tendo sido realizada um análise detalhada dos efeitos dos cruzeiros na qualidade do ar da cidade.
Foi possível verificar que a grande maioria dos poluentes estão em conformidade com os valores guia da Organização Mundial de Saúde (OMS) e com as normas da União Europeia (EU). Concluiu-se que os navios de cruzeiro têm um impacto negativo na qualidade do ar, mas não o suficiente para diminuí-la, sendo o tráfego rodoviário a maior fonte de poluição da cidade de Lisboa.
Abstract Cruise tourism is a sector that combines leisure, sports, education, and other services. Since the 1960s, it has become a significant contributor to the global economy, boosting tourism and local consumption. However, its environmental impacts are substantial, with high emissions of air pollutants and greenhouse gases (GHGs) affecting air quality and contributing to global warming. This study aimed to identify and assess the impact of cruise ships on the air quality of Lisbon. This work was conducted in collaboration with the Administration of the Port of Lisbon (APL), which facilitated the collection of data from various sources. Inspections were carried out on cruise ships to gather information on general characteristics, fuel consumption, scrubber use, waste management, and emissions. Additionally, reports from SondarLab provided meteorological data and hourly pollutant measurements from stations near the port. Other data sources included the Janela Única de Logística (JUL) platform, which supplied technical details about the ships, and the Vessel Traffic Services (VTS), which recorded strategic timelines of ship movements, complemented by a nearby meteorological station. Statistical analysis evaluated the sample's representativeness, and a Gaussian plume model, parameterized in Excel, was used to predict and quantify the emission impacts. The results were compared with real data, followed by a detailed analysis of cruise ship effects on Lisbon's air quality. The findings revealed that the majority of pollutants were within the World Health Organization (WHO) guideline values and the European Union (EU) standards. The study concluded that while cruise ships negatively affect air quality, their impact is not significant enough to cause a substantial decline. Instead, road traffic remains the primary source of pollution in Lisbon.
