Norwegian domestic regulations The Environmental Agreement (NOx Fund in Norway when trading domestic). The Environmental Agreement on NOx 2011-2017 was signed on the 14th of December 2010 by 15 business organisations and the Ministry of the Environment. The agreement is an extension of the the Environmental Agreement on NOx for the period 2008-2010. The Environmental Agreement - and the Participant Agreement - constitutes the framework for the efforts of the Business Sector’s NOx Fund. Through this Agreement, the Business Organisations shall facilitate concrete reductions of the nitrogen oxide gases harmful to the environment. Undertakings which sign the Agreement will be exempt from paying NOx tax in return for their commitment to the obligations laid down by the Business Sector’s NOx Fund whose primary task is to provide funding for NOx reducing measures. The Agreements are important contributions to meet Norway’s commitments in the Gothenburg Protocol for 2010 and the future NOx commitments Norway will receive in 2020. In addition, the work ensures improved calculations on NOx emissions. The Environmental Agreement 2011-2017 In total, the Business organisations shall facilitate emission reductions stipulated in the Agreement 2011-2017 to 16,000 tonnes of NOx, as well as maintain the effect of the obtained emission reductions for the entire period. The Agreement has for this period both yearly and two-year goals to fulfil.

LNG is available – increased demand will ensure even better distribution network. Dual fuel engines are the choice when enough LNG cannot be carried to complete the voyage. Where the application allows single fuel marine gas engines: • More efficient • Less expensive in terms of operating and life cycle cost. • Lower emissions, • Less complex engine supporting systems. • Green profile for the ship owner – marketing tool. • Lower lube comsumption • Lesser or no sludge • No oil spil during bunker operation • Better working environment for engine crew Fjord Line have received financiel support From EU / Ten-T programme Norwegian Nox Fund Thx for Your attention Questions ?
