Methodology
To calculate the emissions of carbon dioxide and hydrocarbons from Swedish leisure boats, Point identified three main emission indicators that formed the basis for data collection.
In order to create the basis from which a sufficiently accurate estimate could be developed, data on the boats’ engines, how much they are used and what fuel they run on needed to be collected. For these purposes ca 1500 telephone interviews were conducted. The interviews covered 2,010 boats, their engines, nautical miles travelled in 2019 and fuel type used.
In order to be able to calculate emissions, literature studies of current research and collaboration with a number of different experts in the field of chemistry and emissions was conducted.
Deliverables
The process and result of the project was compiled in a detailed report as well as in the form of a datafile and calculation model. The datafile and the calculation model was designed to be well-suited as a basis for making decisions about relevant and well-substantiated measures to reduce emissions or otherwise regulate the area of leisure boats.
The report was also formatted so that it could serve as a way of spreading knowledge about the emissions of leisure boats, not least to the boat owners themselves. Point has presented the study at several conferences, e.g. the Swedish Boating Union’s environmental conference and a press-conference led by One Water Foundation, about a fossile free future for the Stockholm Archipelago.
