Environmental Ship Index (ESI) to evaluate CO2 performance

Basic RGB

From July 1, 2017, the Environmental Ship Index (ESI) started evaluating performance in the field of CO2. Until then, only the environmental performance of ships on emissions of air pollution (NOx and SOx) were assessed. This makes the index the first sustainable quality mark in international shipping that includes the performance and, more particularly, the reduction in CO2 in its assessment.

 

The index does this based on historical data already included in the index. The ESI compares the fuel consumption and the nautical miles travelled in the past three years (e.g. 2013, 2014, 2015) to that of the following year (2016). If relatively less fuel has been consumed – in other words, if sailing was more efficient – then less CO2 has been emitted. ESI has chosen for this method because it is actually very difficult to measure CO2 emissions.

 

Environmental Ship Index (ESI) still going strong

According to Fer van de Laar, Bureau Director of IAPH’s World Ports Climate Initiative (WPCI) 5,804 ships are registered and 50 incentive providers, as of July 1, 2017. The number of registered ships (+307) increased compared to April 1, 2017.
