Port areas play a key role in the economic well-being of modern societies by facilitating trade, creating jobs, generating revenue, improving sea transport efficiency and promoting regional development. One of the biggest concerns associated is related with high levels of greenhouse gases emissions. The present work aimed at quantifying the emissions generated by several mobility alternatives (road, maritime and rail modes) carried out in Aveiro and Figueira da Foz ports, located in the Centre region of Portugal and propose a Mobility Decarbonization Plan in small-medium size Ports. PTV VISSIM microscopic model was used to assess vehicles flows to/from/inside the Ports. Using the methodology EMEP/ EEA, the results indicate that 19 600 t and 6 750 t of CO2 were emitted in Aveiro Port, and 4 900 t and 1 900 t of CO2 emissions in Figueira da Foz Port for the years 2022 and 1990, respectively. Subsequently, alternative scenarios concerning alternative fuels, electrification and intermodality were analyzed. Among the measures studied with the greatest potential for reducing CO2 emissions are onshore power, electrification of cargo handling equipment, cargo modal shift from road to rail transport and the use of B100 as alternative fuel. Finally, the mobility decarbonization plan based on the alternative scenarios was designed.

摘要

Port areas play a key role in the economic well-being of modern societies by facilitating trade, creating jobs, generating revenue, improving sea transport efficiency and promoting regional development. One of the biggest concerns associated is related with high levels of greenhouse gases emissions. The present work aimed at quantifying the emissions generated by several mobility alternatives (road, maritime and rail modes) carried out in Aveiro and Figueira da Foz ports, located in the Centre region of Portugal and propose a Mobility Decarbonization Plan in small-medium size Ports. PTV VISSIM microscopic model was used to assess vehicles flows to/from/inside the Ports. Using the methodology EMEP/ EEA, the results indicate that 19 600 t and 6 750 t of CO2 were emitted in Aveiro Port, and 4 900 t and 1 900 t of CO2 emissions in Figueira da Foz Port for the years 2022 and 1990, respectively. Subsequently, alternative scenarios concerning alternative fuels, electrification and intermodality were analyzed. Among the measures studied with the greatest potential for reducing CO2 emissions are onshore power, electrification of cargo handling equipment, cargo modal shift from road to rail transport and the use of B100 as alternative fuel. Finally, the mobility decarbonization plan based on the alternative scenarios was designed.
