“…Yet there is no internationally agreed-upon list for environmental goods or LCTs, though several lists have been developed for varying reasons (see Box 9.2). The use of different lists of environmental goods and of LCT products complicates the interpretation of analytical 2 For a discussion on decarbonizing power generation and consumption, see Bogdanov and others (2021); for the maritime sector, see Englert and Losos (2021); for steel, see Nimubona and Benchekroun (2021); for cement, see Habert and others (2020); for carbon capture-based aviation fuels, see Friedmann and others (2020). 3 Three of the four 1.5°C-aligned scenarios of the Intergovernmental Panel on Climate Change (IPCC) require large-scale negative emissions in the second half of this century; see IPCC (2018).…”

“…Averaging Maritime transport is one the major air polluters in the world. It is estimated that shipping's share of global anthropogenic greenhouse gas emissions (GHG) was 3% and 15% of the world's air pollutants in 2018 [7]. Multiple studies show a positive correlation between increased concentrations of pollutants and vessel traffic [8].…”

European ports are struggling to install enough shore power connections to follow the European Commission initiative, which insists ships that lie alongside to be plugged in and have their auxiliary engines off in EU ports by 2030. The port of Helsinki is one of the busiest passenger ports in the world handling on average more than 10 million international passengers per year. As passenger ships consume more fuel than other vessel types, the shore power regulation poses additional challenges for the port of Helsinki. Passenger ferry and cruise ship terminals are in the middle of the city meaning that their air emissions carry a public health burden in the urban areas. Using port arrivals and departures combined with the EU Monitoring, Reporting and Verifying (MRV), this study estimates that 75–80% of the fuel combusted by ship auxiliary engines falls under the upcoming regulation. However, using statistical methods to find the association and effects between vessel movements and port air quality measurements, ship departures were found to have noticeable increases in the hourly mean NO2 concentration measured at the port terminals. This is most likely caused by starting cold main engines for departure and will not be solved by connecting ships to shore power.

In recent years, the decarbonisation of international shipping has become an important policy goal. While Integrated Assessment Models (IAMs) are often used to explore climate mitigation strategies, they typically provide little information on international shipping, which accounts for around 0.75 GtCO2/yr. Here, we perform the first multi-IAM analysis of international shipping, drawing on the results of six global models. Results indicate the need for decreasing emissions in the next decades, with reductions up to 88% in 2050. This is primarily achieved through the deployment of low-carbon fuels. Models that represent several potential low-carbon alternatives tend to show a deeper decarbonisation of international shipping, with drop-in biofuels, renewable alcohols and green ammonia standing out as the main substitutes of conventional maritime fuels.
