Pollution from shipping is a substantial contributor to climate change. Greenhouse gas emissions from ships include carbon dioxide (CO2) and pollutants such as nitrogen oxides (NOx), sulphur oxides (SOx) and unburnt hydrocarbon particulate matter (PM). Download the EVDI Methodology.
The IMO states that annual CO2 emissions from the international and domestic shipping industries currently exceeds 1 billion tonnes per annum and are increasing. This figure is projected to almost treble by 2050, hindering efforts to reduce global greenhouse gas emissions.
The sector is able to reduce emissions with fuel-efficient ships, using modern IMO-compliant engines, other currently available technologies and low sulphur fuel.
To date however it has been very difficult to identify which ships are the most energy efficient – an important driver of the uptake of environmental technologies.
ShippingEfficiency.org has been designed to address this problem, providing an objective tool for ship owners, operators, shippers and other stakeholders to make sustainability a key part of their decision-making processes. The site draws on work undertaken by the International Maritime Organization (IMO) in developing an Energy Efficiency Design Index (EEDI) which provides objective measures of the efficiency of both new and existing ships.
The shipping industry thus has quick and easy access to vessel efficiency data based on this universally applicable index.
EVDI™ & GHG Emissions
The Existing Vessel Design Index (EVDI™) and Greenhouse Gas (GHG) Emissions Rating was developed by the ShippingEfficiency.org and RightShip to:
– increase information flows around international shipping’s energy efficiency; and
– help reduce the environmental impacts of the world’s shipping fleet.
Similar to the IMO MEPC’s Energy Efficiency Design Index (EEDI), EVDI™ measures a ship’s CO2 emissions, however unlike the EEDI that is applied new ships from 2013, the EVDI™ was designed to be applied to the existing fleet.
The EVDI™ is calculated using characteristics of the ship at build, incorporating parameters that include:
– ship capacity;
– engine power;
– design speed; and
– fuel consumption.
To determine a ship’s Existing Vessel Design Index (EVDI™) value, ShippingEfficiency.org
– IHS Fairplay;
– RightShip’s Ship Vetting Information System (SVIS™);
– classification societies;
– owner’s data; and
– ship-sourced data.
