Ships cut port-side emissions

Göteborg

Detailed description of the Good Practice

Göteborg, Sweden, adopted a system that cuts emissions by 94-97% for ships at berth. It has done this by using renewable energy from wind turbines to power ships at berth. Currently most ships get their electricity supply through onboard power generation by auxiliary diesel engines – a highly polluting and energy consuming method. In 2004, the scheme won the European Commission’s 'Clean Marine Award’ for outstanding environmental achievement. While Göteborg does this on a small scale it has great potential to be expanded.

Objectives of the Good Practice

to cut emissions by 94-97% for ships at berth by using renewable energy from wind turbines to power ships at berth.

Participants of the Good Practice

City of Göteborg

Funding of the Good Practice

  1. Total costs for the installation and maintenance of Onshore Power Supply systems can vary from as little as 60,000€ to 500,000€ per quay.
  2. Göteborg spent around €250,000 on each quay. In total, Göteborg has 5 quays with the system and each quay has its own substation.

More Details of the Good Practice

C02 emissions reductions

  • Emissions at berth reduced 94-97% by participating ships
  • Around 10 ships using scheme, including those of Stena Line ferry company
  • 235.07 tonnes per year for an average ship (statistic from recorded data, 2003-6)
  • 2394 tonnes of CO2 saved in 2003 by six ships
  • Dramatic falls in levels of Nitrogen Oxide, Sulphur Dioxide and other pollutants
  • Expected rise in participating ships, especially after 2010, when ships will be required to burn either 0.1% sulphur distillate fuel or use Onshore Power Supply during port stays in the EU. Both will drastically cut CO2 emissions for shipping.
  • Estimated 60% of EU-flagged vessels are regular services that warrant implementation of shore-side power.
