Reducing GHG emissions from ships in a port area
Journal article, 2015
Climate change has recently received more attention in the shipping sector. This is mainly due to a growing
demand for reduced global emissions and the fact that shipping is one of the fastest growing sectors in terms
of greenhouse gas (GHG) emissions. In parallel, ports have started to introduce programmes and policies to
address these emissions.
This study aims at quantifying potential reductions of ships' emissions of GHG fromefforts implemented by ports.
Building on a model that calculates GHG emissions from ships in various scenarios for individual ports, different
kinds ofmeasures for emission reductions are investigated for diverse types of vessels and parts of the port area.
A case study of the ship traffic to the Port of Gothenburg is performed. Projections of ship emissions in the port
area for 2030 are made, and three scenarios, ‘1. Alternative fuel’, ‘2. Ship design’ and ‘3. Operation’, are analysed.
These scenarios are related to a business as usual development. GHG emissions from ships in the port are
projected to increase by 40% to 2030 in a business as usual (BAU) scenario. The highest reductions were seen
in the ‘Operation’ scenario where GHG emissions were 10% lower than the BAU level.
