The environment is an integral part of our development model. Its protection is both a prerequisite for the success of our businesses and a source of competitiveness.

At TotalEnergies Marine Fuels, we strive to achieve the highest possible environmental standards through the whole delivery chain, from the refinery or LNG terminal to the customer vessel.

Our objective is clear – zero pollution incidents on land or sea. Here are ways we safeguard our environment:

Vessel Technical Standards

All our bunkering vessels are stringently vetted against the highest international standards before we use them to supply our customers, ensuring that our fuel are delivered safely and cleanly.

Environmental Regulations

In 1973, the International Maritime Organization adopted the International Convention for the Prevention of Pollution from Ships, now known universally as MARPOL, which has been amended by the Protocols of 1978 and 1997 and kept updated with relevant amendments. MARPOL has greatly contributed to a significant decrease in pollution from international shipping and applies to 99% of the world’s merchant tonnage. Here are some of the salient regulations in the maritime industry:

On 27 October 2016, the International Maritime Organization (IMO) announced a global limit for sulfur in fuel oil used on board ships of 0.50% m/m (mass by mass), which came into effect from 1 January 2020. It represented change on an unprecedented scale for the refining industry, as well as a huge logistics challenge for both traders and bunker suppliers.

In Emission Control Areas (ECA) defined in the MARPOL by IMO, the limit for sulphur in fuel oil remains at 0.10% m/m.

The NOx control requirements of Annex VI of MARPOL 73/78 apply to installed marine diesel engines of over 130 kW output power. Depending on the ship construction date and operating area, ships have to comply to different tiers of NOx emission limits:


Ship construction date on or after

Operating Area

I 1 January 2000 Outside ECAs*
II 1 January 2011 Outside ECAs
III 1 January 2016 North American ECA
United States Carribean Sea ECA
1 January 2021 Baltic Sea ECA
North Sea ECA

*ECA: Emission Control Areas

Tier III NOx standards impose an 80% NOx reduction versus Tier I NOx standards.

In 2011, the Marine Environment Protection Committee (MEPC) approved a new resolution introducing the Energy Efficiency Design Index (EEDI) as a technical measure to promote more energy efficient (less polluting) equipment and engines.

The EEDI is expressed in grams of carbon dioxide (CO2) per ship’s capacity-mile. The smaller the EEDI, the more energy efficient the ship is. Entered into force in 1 January 2013, the resolution requires new ship designs to meet the 2014 standard reference EEDI for their ship type. Following a 2 year phase zero, this reference EEDI is reduced incrementally every 5 years.


Phase 0 1 2 3
Year 2013-2015 2015-2020 2020-2025 2025+
EEDI - 10% reduction 20% reduction 30% reduction


In October 2016, the Marine Environment Protection Committee (MEPC) approved a roadmap for the development of a comprehensive IMO strategy on the reduction of GHG emissions from ships. This roadmap led to the adoption of the Initial IMO GHG Strategy in April 2018.

The Initial Strategy identifies levels of ambition as follows:

1. Carbon intensity of the ship to decline through implementation of further phases of the energy efficiency design index (EEDI) for new ships

See Energy Efficiency above


2. Carbon intensity of international shipping to decline

Reduction of CO2 emissions by 40% by 2030, and by 70% by 2050, compared to 2008


3. GHG emissions from international shipping to peak and decline

Reduction total annual GHG emissions by at least 50% by 2050, compared to 2008


The Initial Strategy also includes candidate short-, mid- and long-term further measures, to be finalized before 2023, 2030 and beyond 2030 respectively.
