DNV GL charts greenhouse emissions

DNV-GL-Low-Carbon-Shipping-Towards-2050Class society DNV GL has published a report assessing the potential for greenhouse gas (GHG) emissions reduction from shipping towards 2050, based on a new computational model.

In ‘Low Carbon Shipping Towards 2050’, DNV GL explains its computational model can be used to assess various scenarios for individual ship segments and the impact and cost of GHG emissions-reducing solutions.

“Despite the challenges facing our industry, we believe it is technically possible for shipping to achieve substantial GHG reductions, provided a viable strategy is developed and adopted from within the industry itself,” said Christos Chryssakis, group leader energy efficiency & fuels at DNV GL. “But for such a strategy to be both successful and minimally disruptive, it should recognise the differences between the various shipping segments and the need to develop appropriate solutions for different ship types, sizes and types of operation

.”The model uses AIS data to create a fuel consumption and emissions baseline, combining it with scrap and trade growth assumptions for each segment and four main categories of CO2 reduction: Alternative fuels, energy efficiency measures, speed reduction and carbon pricing. For each vessel in the fleet (both existing and new), there is a cost-benefit calculation for alternative fuel options and energy efficiency measures.Once the technology selection is completed, the new level of fuel consumption and emissions is calculated, as well as the estimated cost of implementing these options.The model can be used by ship owners trying to identify the optimum solutions for their vessels, local authorities developing strategies and supporting mechanisms for reducing emissions from vessels in their geographical areas and policy makers developing a global strategy for reducing GHG emissions. -
