Carbon emission from ships

The International Maritime Organization (IMO) has announced new regulations that aim to reduce carbon emissions from shipping by 50% by 2050. 
The IMO has introduced guidelines for engine maintenance and overhaul periods as part of these regulations. 
However, there is a concern that exceeding these periods could actually lead to increased CO2 production by the engines.

There are several reasons why exceeding engine manufacturers’ maintenance and overhaul periods could increase CO2 production. 
Firstly, engines that are not adequately maintained are likely to consume more fuel, leading to increased emissions. A study by the European Environment Agency found that poorly maintained engines can increase fuel consumption by up to 50%, 
resulting in higher CO2 emissions (European Environment Agency, 2013).

Secondly, engines that are not overhauled at the recommended intervals are more likely to experience wear and tear, leading to reduced efficiency and increased emissions. A study by the International Council on Clean Transportation found that 
properly maintained engines can reduce fuel consumption and emissions by up to 15% (International Council on Clean Transportation, 2016).

Finally, exceeding maintenance and overhaul periods can also result in increased emissions of other pollutants, such as nitrogen oxides (NOx) and particulate matter (PM). These pollutants are harmful to human health and the environment and can contribute to climate change.

In conclusion, there is strong evidence to suggest that exceeding engine manufacturers’ maintenance and overhaul periods can lead to increase CO2 production by the engines. Proper maintenance and overhaul are crucial for reducing fuel consumption, improving efficiency, and reducing emissions. Therefore, it is essential that the IMO’s guidelines are followed to ensure that shipping plays its part in 
the global effort to combat climate change.
