An IMO-commissioned study into the impact of mandatory energy efficiency measures for international shipping shows that implementation of the[ds_preview] measures will lead to significant reductions of greenhouse gas (GHG) emissions from ships, specifically reductions of carbon dioxide (CO2), resulting from enhanced fuel efficiency.
Amongst the key findings the report, which was undertaken by Lloyd’s Register (LR) in partnership with Det Norske Veritas (DNV), found that:
• By 2020, an average of 151.5 million t of annual CO2 reductions are estimated from the introduction of the EEDI for new ships and the SEEMP for all ships in operation, a figure that by 2030 will increase to an average of 330 million t annually.
• Compared with Business as Usual (BAU), the average annual reductions in CO2 emissions and fuel consumed are estimated between 13 % and 23 % by 2020 and 2030, respectively.
• Significant reduction of CO2 emissions from ships due to EEDI and SEEMP regulations is foreseen for 2050 with emission reduction due to SEEMP likely to be realised more rapidly than that for EEDI, as the effect of EEDI will occur only as and when older, less efficient, tonnage is replaced by new, more efficient tonnage.
• The estimated reductions in CO2 emissions, for combined EEDI and SEEMP, from the world fleet translate into a significant annual fuel cost saving of about 50 billion $ in 2020 and about 200 billion $ by 2030; using fuel price increase scenarios that take into account the switch to low-sulphur fuel in 2020.
