DP World Southampton announced the launch of new hybrid equipment that will enable it further reduce its emissions and carbon footprint. According to the port's statement, the new hybrid equipment commenced its operation this week.

SEA\LNG and SGMF launched a study according to which GHG reductions of up to 21% are achievable now from LNG as a marine fuel, in comparison to the existent oil-based marine fuels over the entire life-cycle from Well-to-Wake (WtW). The study also confirms that emissions from SOx, NOx and particulate matter, are close to zero when using LNG compared with current conventional oil-based marine fuels.

Shipbuilder Meyer Turku informed that Costa Smeralda was floated out with traditional ceremonies at the Meyer Turku shipyard, on March 15. The float-out of Costa Smeralda, an LNG fueled 180 000 GT cruise ship, signals the start of the final stage of construction for the ship. The ceremony marks the outfitting phase in the ship’s construction. The ship will be ready for delivery for Costa Cruises in October 2019.

Hapag-Lloyd Cruises announced that it will use low-sulphur Marine Gas Oil on all expedition ships from July 2020. Currently, the company is using MGO in particularly vulnerable areas like the Arctic, Antarctica and Kamchatka. The routes will be managed on the basis an eco-efficient average speed, which aims to reduce fuel consumption by one third.

There have been critical debates on potential solutions for reducing CO2 and greenhouse gas emissions in all sectors. As part of the Paris Agreement, adopted by consensus on 12 December 2015, long-term goals have been set by several countries around the globe to limit the increase in global average temperature in an effort to mitigate the effects of climate change.

Mr. Antonis Trakakis, Chief Technology Officer at Forward Ships, talks about methane slips from LNG fueled engines. Mr. Trakakis notes that these emissions are not inherent to the natural gas. The problem lies at the applied heat cycle, making the amount of methane slip depend on the technology of each engine.

Already established measures have paved the way for a more environmental-friendly shipping. A key example is the IMO NOx Tier III limits. These limits apply to engines installed on or after 1 January 2016, that are operating in Emission Control Areas and establish a strict limit on their emissions.

The first guide of 'The Port Emissions Toolkit': Assessment of port emissions, incorporates the latest emission inventory methods and approaches. It recognizes that ships do not operate independently from shore-based entities in the maritime transportation system, and that port emission considerations must extend beyond the ships themselves.

Port of Los Angeles has seen an unprecedented 60% drop in NOx emissions compared to 2005, their lowest level to date, according to the Port’s 2017 Inventory of Air Emissions released last week. The inventory also shows the Port container volume reached an all-time high of 9.34 million TEUs through 2017.

As part of its continuous efforts to improve the air quality of domestic shipping transport, the Chinese Ministry of Transport published earlier this week new requirements for NOx shipping emissions. From 1 September 2018, the vessels' engines shall meet IMO's NOx Tier II emission limit.
