Figures explained

Grey: Projected CO2 emissions for year end 2011
Red: Projected bunker fuel spend during 2011
Green: Projected CO2 emissions and bunker fuel spend for year end 2011, with 30% efficiency savings applied.

Figures based upon IMO projections of GHG growth A1B Scenario, (Source: Fig 1. ICCT White Paper 11 – July 2011). These estimates assume business as usual with an increase of 3% in economic growth rate corresponding to growth in the transport demand, composition and activity of the world's shipping fleet.

It is estimated that GHG emissions from international shipping contribute 870 mmt of CO2 to the atmosphere, with an additional 180 mmt attributable to domestic and inland ships in 2007, for a total of 1050 mmt. Under the IMO's scenario analysis, shipping-sector CO2 is expected to climb to between 2,500 mmt and 3,650 mmt by 2050. These are long-run projections and there may be deviations from the trajectories due to market volatility in the short-term.

The maritime industry can reduce its GHG emissions by between 150 million metric tons of CO2 (lower bound) and 520 million metric tons of CO2 (upper bound) with an expected 320 million metric tons of CO2 per year with negative marginal abatement costs (i.e., while improving overall industry costs).

This is on the order of 13 to 46 percent of the 2020 BAU case.

Ports: Support our Memorandum of Understanding calling for an alliance aimed at increasing the economic and environmental sustainability of the shipping industry.

Joint Statement of Intent
For the consideration of fellow maritime industry stakeholders:

We believe it is in our mutual interest to establish an alliance of cooperation aimed at increasing the economic and environmental sustainability of the shipping industry. The goal of this cooperative alliance will be to increase the present level of economic growth and environmental sustainability by reducing operational inefficiencies, reducing dependence on fossil fuels, and reducing carbon emissions within the transportation supply chain. We believe that these efforts will help establish the foundation for a performance-based efficiency measurement for ships that allows beneficial cargo owners and other port customers to maximize shipping efficiencies.

The undersigned parties wish to note that:

– International shipping is an efficient way of transporting goods;
– Shipping contributes to carbon emissions and in order to limit climate change we need to mobilize carbon reduction and energy efficiency in every market segment;
– There is potential for shipping to become as much as 30% more energy efficient through current technologies and measures, and potentially even more;
– Increased efficiency should increase the economic viability and environmental sustainability of the shipping industry; and
– There are established tools available to help identify energy savings.


NOW, THEREFORE, the parties agree to:

– Join the call for ship-owners, operators, shippers, and charter parties - when entering our ports - to report voluntarily the vessel’s the World Ports Climate Initiative’s Environmental Ship Index (ESI);
– Implement commercial and/or operational incentives to encourage the use of above-average vessels in conjunction with existing or planned incentives to encourage the use of low NOx and CO2 and SOx emitting vessels (PM10 is indirectly included because of its strong relationship to SOx) in the form of reduced port fees or similar;
– Collect, maintain, and report ratings of vessels visiting the port on a routine basis; and
– Recognize and highlight the vessels that attain above-average ratings.

We believe these measures to be necessary to lay the foundation of an economically and environmentally sustainable industry in the long term, and will participate in a supportive and appropriate manner to help bring about the evolution necessary to do so.
