EPI Impact

The Environmental Port Index, or the EPI, is a sophisticated but simple to use reporting tool, designed to help ship owners and port operators to chart a course for positive change.

Average EPI Scores

An EPI Score of 0 (worst) to 100 (best) indicates how effectively a ship’s sustainability efforts have exceeded the internationally recognised “Baseline” requirements for that vessel. Below is the average EPI score of all ship calls this year and over the lifetime of the EPI. Our aim is to see EPI scores rise year on year, to reflect positive change in our industry.

Total Emissions (tonnes)

Improving local air quality and fighting the global crisis are key objectives of the EPI. Below shows the reduction in NOx and SOx emitted into portside community air, as well as ozone damaging CO2 emissions, across all EPI port calls this year. This is shown in metric tonnes year to date, as well as a Year on Year % reduction.

Fuel Consumption (tonnes)

The various types of fuel used by ships during port calls have different effects on operational sustainability. Heavy Fuel Oil (HFO) is the most pollutant, impacting both local air quality (NOx and SOx) and global warming (CO2). Marine Gas Oil (MGO) emissions are similar, but it is does not need to be pre-heated like HFO.

In comparison, LNG and LPG can improve local air quality by emitting far less NOx and SOx, as well as slightly less CO2. Alternatively, Biofuel produces the least CO2 and zero SOx, but with relatively high levels of NOx. Currently there is no truly clean fuel, but we hope to see a shift away from Heavy Fuel Oil as we move forward.

Energy Consumption (MWh)

Using sustainable energies to power auxiliary systems at quay is a great way to reduce ships’ air pollution and climate impact. Batteries have an environmental cost to produce, but can significantly lower NOx, SOx and CO2 emissions. Hydrogen fuel cells emit only water, with no greenhouse gases or local air pollution. And Shore Power, so long as the source is renewable, offers totally green energy with the potential benefit to support a port’s local economy and the GDP.
