How is long-haul shipping responding to the climate crisis?

in Decarbonization, News, Trends by

If the global shipping industry were a country, it would be the world’s sixth-highest CO2 emitter, ahead of Germany. As an international industry, shipping was not covered by the 2015 Paris climate change agreement that focused on individual nations’ responsibility for critical emissions. But as unprecedented heatwaves, forest fires and flooding raise global awareness of climate change, the shipping industry is starting to make up for lost time.

How significant is their response? And was Maersk’s recent announcement of investing over US$1.4bn in eight post-Panamax containerships that can run on methanol or bunker fuel just a drop in the proverbial ocean? Let’s take a closer look at how shipping is responding to the climate crisis.

Sustainable Trends to Watch Out for in Logistics

in Decarbonization, News, Trends by

Author: Charlotte Murphy

In 2021, the maritime logistics industry can scarcely afford to ignore its environmental impact. The transportation industry is a major contributor to greenhouse gas emissions, so it’s no surprise that sustainability has become a key trend in logistics. Fortunately, the future looks bright with innovative solutions and emerging technologies that promise to lessen the ecological footprint and boost performance. Here’s a closer look at some things to keep a look out for, going forward.

Is the Shipping Sector on Track to Meet Climate Targets?

in Decarbonization, Research, Trends by

FleetMon supports ETH researchers to find the answer.

Fighting climate change demands action in all sectors. International shipping faces the challenge of long lifetimes of vessels compared to other modes of transportation. Decisions on energy carriers and propulsion technologies that are made now have a long-lasting impact on the emissions of the sector. 

A research group at the Institute of Energy Technology at ETH Zürich led by Prof. Dr. Konstantinos Boulouchos developed a fleet turnover model for the shipping sector to estimate its future CO2 emissions up to 2050. Thereby, the CO2 emissions of existing ships and those of new ships entering the fleet yield yearly emission figures. However, up until recently, a missing puzzle piece for such models has been how long existing ships will actually still be in service. Missing or prohibitively expensive data has prevented analyses on this topic.

Green Ammonia – the Key to Decarbonizing Shipping?

in Decarbonization, Trends by

There’s no doubting the magnitude of the problem. And the urgent need to tackle it. Maritime shipping accounts for nearly 3% of the world’s annual CO2 emissions, says the IMO. In 2018, IMO delegates agreed to cut emissions by 50% from 2008 levels by 2050. But with less than three decades to go, the target seems more unattainable than ever. Developing viable alternatives to diesel fuel is a more time-critical challenge than ever before. Can green ammonia solve shipping’s carbon crisis?

FleetMon supports students and research partners when it comes to providing AIS data for academic purposes. In 2020, a Ph.D. student from the Department of Engineering Science of the University of Oxford reached out to us to receive certain AIS data for a project on the decarbonization of crucial shipping routes.

Insights on Emission Reduction With AIS Data

Researchers at ETH Zurich provide new insights on the emission reduction potential of shore-side electricity using AIS data from FleetMon.

The urgency for climate action expressed by the Intergovernmental Panel on Climate Change (IPCC) demands a rapid market uptake of CO2 reduction measures in all sectors. For international shipping, the European Commission has frequently emphasized the important role of providing shore-side electricity to ships at berth, being a rather simple way of reducing CO2 emissions of ships, but also due to considerable co-benefits: Local air pollution in sea ports is primarily caused by emissions of ships at berth and poses a severe threat for premature mortality on the local residents.

Paving the way for a greener future

To date, IMO is the only organization worldwide that has adopted energy efficiency measures that are legally binding across the world. IMO also regulates the emission standards for ships, which are more strict in areas designated as Emission Control Areas (ECAS). As the MARPOL Annex 6 regulations restricting air pollution, another of IMO’s measures, is progressively setting more exacting standards, the shipping industry is looking for alternatives; such as ships powered by distillate fuels, using scrubbers, alternate fuels such as LNG, Hydrogen, or ammonia, even nuclear powered or completely battery-powered ships are a possibility. However one of the most feasible possibilities in the short to mid future is LNG.

Zero-emission ports: Towards “greener” pastures

Climate change is shaping to be one of the most prominent threats so far in the 21th century. With the shipping industry being an inextricable part of global logistics, it contributes to about 18 percent of some air pollutants. The International Maritime Organization (IMO), with this in view has adopted regulations to reduce emissions of Greenhouse Gases (GHG). The directive in MARPOL annex 6 to reduce sulfur emissions to 0.5% is currently being enforced since 1st January 2020.
