Recently, the Parliament was informed about Government efforts to clear the uncertainty of the Shipping industry on reducing sulphur oxide emission levels.
- From 1 January 2020, usage of sulphur in fuel oil used on board ships will be capped and reduced to 0.50% m/m (mass by mass).
- The main type of bunker oil (heavy fuel oil for ship) is derived as a residue from crude oil distillation and it contains sulphur. On combustion in the engine, it emits oxides of sulphur.
- Sulphur oxides are harmful to human health, causing respiratory symptoms and lung disease. In the atmosphere, they lead to acid rain harming crops, forests and aquatic species and contributing to the acidification of the oceans.
- International Maritime Organisation (IMO) regulations to reduce sulphur oxides emissions from ships first came into force in 2005, under Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL Convention, 1973).
- India is a signatory to this International Convention and all its Annexes.
- Limiting sulphur oxides emissions from ships will improve air quality and protect the environment. It will have major health benefits particularly for populations living close to ports and coasts.
