Emission reductions and costs of abatement measures for air pollutants and greenhouse gases from shipping: selected measures with importance for the Swedish Environmental Quality Objectives


This report is part of the Carrot and Sticks project which has the overall objective to analyse policy instruments and measures that most cost-effectively can reduce air emissions from maritime transport in Sweden. The objective of the study presented in this report is to assess cost estimates for abatement options for measures reducing air emissions of Sulphur dioxide (SO2), nitrous oxides (NOX), particular matter (PM) and greenhouse gases (GHGs) from shipping, along with estimates of emission reductions. The emission reductions in turn contribute to the fulfilment of the Swedish Environmental Quality Objectives; Clean Air, Natural Acidification Only, Zero Eutrophication and Reduced Climate Impact. The results in this report are used as input in a simplified cost-benefit analysis, that is used to derive policy recommendations

A selection of measures that can reduce air emissions from shipping impacting the Swedish Environmental Quality Objectives related to air emissions are analysed in terms of emission reductions and costs for shipowners. The time perspectives for the reductions are focused on 2030 and 2045, but also consider costs in the base case 2015. The analysed abatement measures are:

  • • Fuel switches, from MGO (Marine Gas oil) to LNG (liquified natural gas), LGB (liquified biogas), fossil and renewable methanol
  • • Full electrification by rechargeable batteries
  • • Onshore power supply (OPS)
  • • Selective Catalytic Reduction (SCR)
  • • Wind power (by Flettner rotors)
  • • Energy efficiency measures including advanced route planning, optimized propeller, slender hull,

and hybridization

  • • Speed reduction

The cost calculations are made from a shipowner’s perspective, including investment costs for installing the abatement technology on the ship, changed operational and maintenance costs and, in many cases, cost savings due to reduced fuel consumption. Associated costs that are (not obviously) taken by the shipowner/ operator are not included. Costs per year are calculated for a base- case 2015 with cost estimates and fuel prices for 2015 and for four future fuel price scenarios for 2030 and 2045, based on projections for fossil fuel prices by the International Energy Agency.

Additional policy instruments are needed to achieve Swedish environmental quality objectives for maritime transport

Achieving the national and international environmental objectives for maritime airborne emissions requires a combination of new and more powerful policy instruments. The policies already in place are not enough. This is one of the conclusions of a research...


Opportunities for a new market in electrified regional flight

Large, electrified aircraft is far off in the future. On the other hand, there may be potential for a new market with smaller regional flights. These are the conclusions of a literature survey made by researchers at VTI.


Need for standards as electric road systems are developed

The need for standardisation is increasing as electric road systems are reaching higher levels of maturity. A large part of the standards for intelligent transport systems (ITS) assessed in a new VTI and SIS study was considered potentially useful for...


Unique knowledge compilation on microplastics from road traffic

Although we know that tyre and road surface wear generates significant emissions of microplastic particles, knowledge about them is very limited. This is the conclusion of a report issued by the Swedish National Road and Transport Research Institute (VTI).


Measures for infrastructure climate adaptation requires prioritisation

The effect of climate change will result in more extreme weather events causing for example increased risk of floods, and landslides, which will result in great costs to society. Therefore, society needs to prepare for the consequences brought on by climate...


Increased interest in train simulators

VTI has developed a train simulator that has become a valued tool in train driver education and research on how simulators can be used to improve railway technology.
