BC, SO2, O3 concentrations and BC depositions with/without Arctic diversion traffic. Fishing ships account for most emissions, improved estimates is a future focus area. Without diverted traffic BC[NO , SO ] emissions change by 16[32, 63] % from 2012 to 2050. x 2 High 2050 Arctic route BC (80%) and SO2 (1000%) concentrations added from ships. a r t i c l e i n f o a b s t r a c t Article history: This paper presents a detailed BC, NOx and SO2 emission inventory for ships in the Arctic in 2012 based Received 12 September 2013 on satellite AIS data, ship engine power functions and technology stratified emission factors. Emission Received in revised form projections are presented for the years 2020, 2030 and 2050. Furthermore, the BC, SO2
