CO
Emissions of CO were determined by the method originally described in Sarvi et al. (2008) and included in
Jalkanen et al. (2012). The methodology describing transient engine loads and their changes were not used and
all CO emissions factors represent steady-state operation and emissions. For main engines, PM was adjusted
for low engine loads (
