Why Understanding CO2, NOx, and SOx Emissions in Shipping and Ports is important

How can the maritime sector, through embracing a collaborative approach, unlock synergies and efficiencies that benefit shipping and ports while advancing toward shared sustainability goals? It will require collaboration between all parties to break down the silos, fostering open communications and cooperation and viewing emissions reduction as a collective endeavour rather than an individual mandate. Ultimately, by working together, shipping and ports  (good example of this is the Singapore Green Initiative) can maximize their positive impact on the environment, society and the economy, paving the way for a more sustainable future.

This is why understanding CO2, NOx, and SOx emissions in shipping and ports is crucial for addressing maritime pollution’s environmental and health impact. 

Putting this into context, while the maritime sector serves as the backbone of global trade and will continue to do so, it also contributes significantly to emissions of carbon dioxide (CO2), nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM). These emissions mainly result from fossil fuel combustion and have massive implications for climate change and importantly, port air quality.

Global and regional regulations are also driving this issue. The International Maritime Organization (IMO) has set targets to reduce greenhouse gas (GHG) emissions from international shipping, with a goal of achieving net zero CO2 emissions by 2050. There is also the Paris Agreement and the European Union’s Green Deal, as well as pressure from local surrounding communities, NGOs and other stakeholders.
