O objetivo geral do presente estudo foi analisar a sustentabilidade com foco na emissão CO2 dos veículos da empresa Luís Simões, no período compreendido entre os anos de 2023 a 2024. Com o apoio metodológico da investigação-ação, procedeu-se inicialmente ao diagnóstico da situação atual das emissões de CO2, por meio da utilização de indicadores-chave de desempenho (KPIs) que permitiram a sua quantificação e monitorização eficazes. Entre esses indicadores, destacam-se as emissões totais de CO2e. A intensidade de emissões por tonelada-quilómetro e o consumo específico de combustível. Os resultados evidenciaram uma intensidade média de emissões de 0,000335 kg CO2e/t·km, bem como uma acentuada heterogeneidade entre os veículos analisados. Posteriormente, foram definidas metas de redução das emissões de CO2, procurando minimizar progressivamente o impacto ambiental. Nesse sentido, considerando a manutenção constante do nível de atividade logística, concluiu-se que a empresa pode alcançar reduções globais de emissões num intervalo estimado entre 30 % e 45 %, por meio da aplicação combinada de melhorias tecnológicas e operacionais. Para a definição de estratégias que integrem tecnologias limpas e contribuam para a redução das emissões, foram consideradas ações como a renovação do parque veicular com unidades Euro VI ou superiores, a utilização de biocombustíveis e a incorporação gradual de veículos movidos a GNL, GNC e, futuramente, tecnologias elétricas ou a hidrogénio verde. Adicionalmente, propôs-se o desenho de um sistema de monitorização contínua que permita avaliar a redução das emissões de CO2 e aplicar os ajustes necessários. Esse sistema, baseado em KPIs, constitui um elemento fundamental para garantir a eficácia das estratégias de redução de emissões. Em conjunto com o uso de ferramentas digitais de gestão e análise de dados, este sistema possibilita a avaliação periódica do desempenho ambiental, a deteção de desvios face aos objetivos estabelecidos e a implementação atempada de medidas corretivas.
The general objective of this study was to analyze sustainability with a focus on the CO2 emission of the vehicles of the company Luís Simões during the period from 2023 to 2024. using an action research methodology as the methodological approach, the current situation of CO2 emission was first díagnosed through the use of key performance indicators (KPIs) that allow for effective quantification and monitoring. These indicators include total CO2e emissions, emissions intensity per tonne-kilometer, and specific fuel consumption. The results revealed an average emissions intensity of 0.000335 kg CO2e/t·km, as well as a marked heterogeneity among the vehicles analyzed. Subsequently, CO2 emission reduction targets were established, aiming to progressively minimize environmental impact. In this context, assuming a constant level of logistics activity, it was determined that the company could achieve overall emission reductions within an estimated range of 30% to 45% through the combined implementation of technological and operational improvements. To develop strategies that incorporate clean technologies and contribute to emission reduction, actions such as renewing the vehicle fleet with Euro VI or higher units, using biofuels, and the gradual adoption of vehicles powered by LNG, CNG, and, in the future, electric or green hydrogen technologies were considered. In addition, the design of a continuous monitoring system was proposed to assess CO2 emission reductions and apply the necessary adjustments. This system, based on KPIs, represents a key element in ensuring the effectiveness of emission reduction strategies. Together with the use of digital management and data analysis tools, this system enables periodic evaluation of environmental performance, detection of deviations from established objectives, and the timely implementation of corrective measures.
