Abstract Emissions from idle truck engines are a main source of pollution from
transportation, and emission reduction from idle truck engines at container termi-
nal has for this reason become a priority. At the import yard of a container termi-
nal, an incoming truck has to wait for its turn to be loaded with containers which
are then to be delivered to a customer. Reducing waiting time of trucks means that
truck emissions are decreased as well as the competition of port increases. In this
study, the emission from idle truck engines at the import yard is considered. The
goal of this study is to develop a methodology for reducing emissions generated
by trucks idling at import yards. The proposed method includes a mathematical
model for minimizing truck emissions. In the model, total truck waiting time in the
yard is estimated using discrete event simulation. To solve this model, a genetic
algorithm is proposed. A case study in a Singaporean port is used for conducting
experiments. The experiment result shows that the manager of a container terminal
should control truck arrivals based on the stacking of import containers in order to
reduce the truck idling time and thereby the truck emissions in the import yard.
