Maritime transport is responsible for approximately 90% of global trade and is considered the least environmentally damaging mode of transportation. However, the maritime industry is continuously making significant advancements in reducing our environmental impact on the planet.

In order to minimize the impact of the maritime industry on the environment, the International Maritime Organization (IMO) developed the International Convention for the Prevention of Pollution from Ships, or MARPOL (which stands for Marine Pollution) in 1973.

The primary objective of MARPOL is to prevent and minimize pollution from ships from both accidental and operational causes, and currently includes six technical annexes:

  • Annex I: Regulations for the Prevention of Pollution by Oil
  • Annex II: Regulations for the Control of Pollution by Noxious Liquid Substances in Bulk
  • Annex III: Regulations for the Prevention of Pollution by Harmful Substances Carried at Sea in Packaged Form
  • Annex IV: Regulations for the Prevention of Pollution by Sewage from Ships
  • Annex V: Regulations for the Control of Pollution by Garbage from Ships
  • Annex VI: Regulations for the Prevention of Air Pollution from Ships

These regulations are enforced by the government through the United States Coast Guard and the Environmental Protection Agency.

HELMEPA (the Hellenic Marine Environment Protection Association) is pioneering voluntary initiative composed of Greek seafarers and ship owners committed to safeguarding the seas from ship-generated pollution. HELMEPA was founded on June 4, 1982 in Piraeus, Greece and has worked to foster a sense environmental consciousness and spirit of safety, among seafarers and ship owners. HELMEPA achieves these goals through a highly-coordinated voluntary effort towards informing, updating, educating and motivating all, from ship owner to the last seafarer. Members are typically ship owners, managing companies and ship’s agents, masters, deck and engineer officers, ship’s crew members as well as other organizations and stakeholders from the broader Greek and international maritime and business community.

HELMEPA’s major operational activities include:

  • Encouraging compliance with both national and international laws and regulations that Greece has ratified and governing pollution prevention

  • Assisting the Greek State in relation to international legislation on the protection of the marine environment.

  • Promoting international efforts to unify international environmental regulations, efforts for the elimination of ship-generated pollution wherever possible, and the improving of safety standards.
