Assessment of potential reduction of emissions

Potential for reduction of CO₂ emissions

5.76 Several options for efficiency improvements have been considered in earlier paragraphs. The potential for energy saving by combining these steps is very vital.

Nevertheless, costs, lack of incentives and other obstacles block many of them from being implemented. Hence, when assessing the potential savings, we also establish clear assumptions regarding the extent of compromise, effort and extra costs that are needed.

An evaluation of potentials for saving energy using present technology and methods is presented in table 5-2. The values given in this table exhibit the variations in benefits for various ship types and the level of motivation to achieve savings.

5.77 Projected efficiency improvements are presented as scenarios in Chapter 7. The high values presented in table 5-2 relate fairly well to the scenario with the highest improvement in energy consumption, in which net improvements, without the use of low-carbon fuels, range from 58% to 75% in 2050, depending on the type ship. This assumption, including indicators of historical transport efficiency for various ship types, is portrayed in figure 5-1. The historical background for the generation of efficiency data is shown in Chapter 9.
