World Enviroment Day


June 5th marked the World Environment Day, which in 2019 focused on creating awareness on air pollution and encouraging action aimed at minimising its effects on people’s health and the environment. It is our mission at IACCSEA to be a catalyst for clean shipping, and in the spirit of the day we would like to take the opportunity to remind everyone about the effects of nitrogen oxide (NOx). Formed in the heat of the marine engine, NOx is a dangerous, acidic pollutant that can be transported over many hundreds of miles and deposited as acid rain. It promotes the formation of ground level ozone, detrimental to human health and is known to exacerbate heart and lung complaints. NOx acidifies its environment and damages plant life in the sea and on land.

There are ways, however, to neutralise the NOx in the exhaust of the marine engine. Selective Catalytic Reduction technologies are a simple, cost-effective and proven NOx reduction solution capable of achieving the emission limits set by the International Maritime Organisation, and in many cases up to 99% reduction of NOx emissions.

IACCSEA to host a pre MEPC 74 event on 12 May to discuss its insights on why the IMO Tier III NOx regulations are not working yet

IACCSEA, the leading authority on catalytic reduction of NOx emissions from shipping, will host IMO MEPC 74 delegates and other esteemed guests from the industry on the evening of 12th of May. The programme will include thought-provoking presentations and discussions on the insights gained from the implementation of IMO Tier III NOx regulation in the North American Emission Control Areas to date and what difficulties need to be overcome in the future. Some of the topics we will discuss include:

  • Since the introduction of IMO Tier III regulation in 2016, there were very few calls by Tier III certified vessels in the North American ECA. This will mean that expected reduction in NOx emissions will not be achieved, as revealed interviews with major US and Canadian ports.
  • What are some of the common difficulties encountered in certifying IMO Tier III vessels and how to overcome them?

This is an invitation-only event held under Chatham House rules, so please get in touch with if you are interested in attending.

IACCSEA – to facilitate the transition to low emission shipping

London. The International Association for Catalytic Control of Ship Emissions to Air, IACCSEA, has been formed with a primary focus of demonstrating the technological and economic viability of Selective Catalytic Reduction (SCR) technology capable of reducing NOx emissions from marine engines.READ MORE
