Marine emissions, particularly those from shipping, are a major contributor to air pollution. In fact, it is estimated that shipping accounts for around 3% of global greenhouse gas emissions. As a result, there has been an increasing focus on monitoring and reducing these emissions in recent years.
Why Monitor Marine Emissions?
Monitoring marine emissions is important for several reasons. Firstly, it allows us to accurately measure the impact of shipping on air quality. This information can then be used to inform policies and regulations aimed at reducing emissions.
Secondly, monitoring can help shipping companies to identify areas where they can improve their environmental performance. This can include measures such as using cleaner fuels, optimizing ship routes, and improving energy efficiency.
How is Marine Emissions Monitoring Done?
There are various methods used to monitor marine emissions. These include:
Direct Sampling: This involves collecting air samples from the exhaust gases of ships and analyzing them for pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter.
Remote Sensing: This involves using sensors to measure emissions from ships as they pass by. This can be done from the shore or from a specially equipped aircraft.
Satellite Monitoring: This involves using satellites to measure emissions from ships over a wide area. This can provide a comprehensive picture of emissions from shipping across the globe.
Challenges and Future Developments
Monitoring marine emissions can be challenging due to the vast size of the oceans and the large number of ships in operation.
In April 2018, the International Maritime Organization (IMO) adopted the Initial Strategy on the reduction of greenhouse gas (GHG) emissions from shipping. The strategy sets key ambitions, including reducing annual GHG emissions from international shipping by at least 50% by 2050, compared with their level in 2008, and working towards phasing out GHG emissions from shipping entirely as soon as possible in this century. In June 2021, the IMO adopted a set of short-term measures to achieve the target of reducing the carbon intensity of shipping by 40% by 2030.
Additionally, many countries are implementing their own regulations to limit emissions in their waters.
Worldwide there is ongoing research into new technologies that can help to reduce emissions from ships, such as alternative fuels and improved engine design.
Monitoring marine emissions is an important step towards reducing the impact of shipping on the environment. By accurately measuring emissions, we can identify areas where improvements can be made and work towards a more sustainable future for the shipping industry.
Distributed by CAC GAS, the ISO 17025 Marine Emissions test kit provides SO2/CO2 calibration gases for marine stack gas analysis. The kit provides the equipment necessary to calibrate and test CEMS (Continuous Emissions Monitoring Systems) to meet airborne pollution levels in the MARPOL Annex VI.
The kit comes with the mobile carrying case; two 3L (600 litres of gas @ 200bar) high pressure cylinders of chosen gas; a compact, single-stage cylinder pressure regulator and tubing.
The case is made of highly impact-resistant plastic. It is temperature resistance between -40 ° C and +80°C. The all-round impact protection features make it shock and impact absorbing. This case is lockable with an ergonomic, telescopic handle and wheels for a secure and convenient solution.
CAC Gas offers a wide range of certified reference materials including specialty gas mixtures, liquids, and liquefied gas standards.
Curated from several industry leading manufacturers, only mixtures that meet CAC’s high standard for quality are supplied to meet the needs of an ever-evolving landscape of analytical applications.
CAC GAS’s range of gases and liquids are available in a wide array of cylinders, bottles and ampoules.
