Data sources

Aviation:• Swedish Civil Aviation Administration

(SCAA)• Statistics Sweden – Monthly oil statistics

(aviation fuels)• Swedish Armed Forces - Military

activitiesNavigation:• Statistics Sweden - Monthly oil statistics

Aviation

• SCAA – Information on domestic and international traffic, divided on LTO and cruise

• Only governmental airports included• SCAA data is adjusted with national

amounts of aviation fuels to cover all civil aviation activities

• Emissions from military aviation activities are reported separately

Aviation

• Difficulties to estimate aviation activities from private airports and within agriculture and forestry.

• Either country-specific or default CORINAIR EF’s are being used.

Monthly oil statistics

• The statistics are based on information of delivered amounts of fuel from wholesale dealers on national level.

• It is a monthly survey which includes all oil trade companies and other liable to maintain stocks of fuels, other companies with large import.

• Mail survey which includes 70 companies

Monthly oil statistics

• The data from the respondents are divided in different cathegories

• One of the cathegories is bunkering for foreign shipping

• Another is domestic shipping(excluding fishery)

• The separation is made by the respondents

Monthly oil statistics

• One problem in the statistics comes from the separation in cathegories

• If the oil is delivered to a ship with final destination in Sweden, it is cathegorised as domestic shipping even if the ship visit a foreign country on its way to final destination
