A Carbon Footprint Assessment on Construction and Maintenance Operations for the Port of Gothenburg - With emphasis on emission reduction actions
Examensarbete för masterexamen
Industrial ecology (MPTSE), MSc
Ports are an industry that emits high levels of CO2 missions. The purpose of this thesis is to minimise CO2-eq emissions from the Port of Gothenburg. Four main objectives are used to achieve this purpose. The first is mapping ports, with respect to CO2-eq emission related activities and reduction targets. Four ports are selected in this report, located in Antwerp, Gothenburg, Los Angeles and Valencia to determine different emission reduction actions. Such actions are a combination of technical development, using same equipment but more efficiently or by change of behaviour. Since no ports have estimated CO2-eq emissions from construction and maintenance operations before, this report serves as a foundation or inspiration for further development of CO2-eq calculations. Emissions from construction and maintenance operations are defined as indirect emissions for Gothenburg Port Authority. The second objective is to collect data for the mass of materials and volume of fuels used in construction and maintenance operations for the Port of Gothenburg. Data from year 2013 is used for the collection of used materials and energy related products. The study includes the 22 most extensive projects out of 160 construction and maintenance related projects. The third objective is to calculate and asses CO2-eq emissions from construction and maintenance operations for the port of Gothenburg. The chosen method for calculating emissions is a carbon footprint assessment and includes a CO2-eq inventory on construction and maintenance operations at the Port of Gothenburg. The carbon footprint assessment uses emission factors in all calculations. The material and energy related products that contribute the most to CO2-eq emissions are fossil fuels and concrete. The total CO2-eq emissions for the 22 projects are approximately 1340 tonnes and in mass approximately 1060 tonnes (excluding fuels). This leads to an increase of 1 % of the current carbon footprint for Gothenburg Port Authority. If using an uncertainty factor with 25 % and including all 160 projects, CO2-eq emissions during 2013 are estimated to be up to 5600 tonnes, which is an increase with 3 %. The conclusions from the mapping and carbon footprint serve as a foundation for the development of guidelines, which operates as emission reduction potential areas. This is the last objective, including suggestions for guidelines on how to reduce CO2-eq emissions in port operations.
