Quarter of EU shipping will run on LNG by 2030 locking in fossil fuels for decades

EU policies to clean up shipping will lead to replacement of conventional marine fuels with fossil liquid natural gas (LNG), with little benefit to the climate. A quarter of Europe’s shipping will be fossil gas-powered by 2030 as misguided EU sustainability targets encourage an uptake of LNG, a new Transport & Environment study shows. This will lock-in fossil fuel use for decades while bringing limited benefits to the climate, says T&E.

Les particules ultrafines dans le viseur d’Airparif

Airparif dévoile les résultats d’une campagne inédite en Île-de-France de surveillance des particules ultrafines (PUF). Ce type de polluant de l’air circule sous forme de particules solides de diamètre inférieur à 100 nanomètres, soit inférieur à la taille d’un virus et qui peuvent être aussi petites qu’une molécule d’ADN. Ce polluant dit "émergent" n’est pas réglementé à ce jour, mais fait l’objet d’inquiétudes sanitaires croissantes et de recommandations de renforcement de leur surveillance de la part de l’ANSES en France et de l’OMS à l’international.

Cleaner fuels for ships provide public health benefits with climate tradeoffs

We evaluate public health and climate impacts of low-sulphur fuels in global shipping. Using high-resolution emissions inventories, integrated atmospheric models, and health risk functions, we assess ship-related PM2.5 pollution impacts in 2020 with and without the use of low-sulphur fuels. Cleaner marine fuels will reduce ship-related premature mortality and morbidity by 34 and 54%, respectively, representing a ~ 2.6% global reduction in PM2.5 cardiovascular and lung cancer deaths and a ~3.6% global reduction in childhood asthma. Despite these reductions, low-sulphur marine fuels will still account for ~250k deaths and ~6.4 M childhood asthma cases annually, and more stringent standards beyond 2020 may provide additional health benefits. Lower sulphur fuels also reduce radiative cooling...

Ships

Shipping is responsible for over a tenth of transport CO2 emissons and is a major source of air pollution. Thanks to decades of inaction, its environmental impact is growing. But switching to green fuels offers a cleaner future. Shipping emits 1,000 Mt CO2 per year, 3% of global CO2 emissions. Its impact is set to increase by up to 120% if other sectors decarbonise successfully and the shipping industry continues to fail to reduce its pollution. The global maritime regulator, the International Maritime Organisation, has repeatedly failed to take action. T&E is the leading environmental organisation in Europe tackling shipping emissions. Shipping also contributes to poor air quality and acid rain. T&E works together with other members of the Clean Shipping Coalition to reduce air...

Comment Marseille veut en finir avec la pollution du transport maritime

Les émissions de fumée des ferries, navires de croisières et porte-conteneurs sont régulièrement dénoncées par les associations écologistes. Plusieurs initiatives industrielles veulent y mettre fin. Produire du carburant bas carbone pour les navires à partir des poubelles de Marseille. Avec cet ambitieux projet d'économie circulaire, quatre industriels de la métropole Aix-Marseille-Provence espèrent endiguer en partie la pollution atmosphérique du trafic portuaire régulièrement dénoncée par les associations écologistes. Le circuit profitera d'infrastructures préexistantes : les unités de méthanisation du centre de traitement des ordures ménagères de l'agglomération produiront du BioGNL avec la partie biodégradable des déchets. Il sera stocké sous forme liquide chez Elengy (filiale d'Engie)...

Shipping Urged to Review LNG Use as Methane’s Role in Climate Change is Revealed

By Nick Savvides (The Loadstar) Members of the Intergovernmental Panel on Climate Change (IPCC), a body of scientists and others from 195 countries, will launch the first of four reports on Monday, which is expected to highlight the growing influence of methane in the warming of the atmosphere. Methane is a key component of liquefied natural gas (LNG), the supposedly cleaner and more efficient transition fuel many in the shipping industry believe will provide a stepping-stone to zero-emission transport. It is also being used increasingly as a replacement for land-based power generation as well as for powering large ships. CMA CGM has ordered 14 LNG-powered vessels, some of which have already been delivered, and Matson, the US Jones Act operator, has also ordered similar ships. While...

Etude d'AtmoSud

Évaluation de l’évolution des émissions des navires dans le port de Marseille en lien avec la crise sanitaire Contexte et objectifs de la note L ’activité maritime et portuaire constitue un des principaux émetteurs de polluants atmosphériques de l’agglomération marseillaise. La crise associée au COVID entraîne la présence d’un plus grand nombre de navires dans le port et surtout un temps de résidence plus élevé. Depuis un an, AtmoSud est régulièrement interrogé par les riverains, les acteurspublics, les médias sur l’impact de ce surcroît de navires dans le port. L ’objectif de cette note est d’ estimer et objectiver l’évolution des rejets des navires par rapport à la période 2018-2019.Les rejets des navires sont liés aux combustions des moteurs, dont les quantités et la qualité dépendent...

Compressed natural gas vehicles are not a clean solution for transport

Review of the latest evidence shows high levels of particle emissions Some claim that compressed natural gas (CNG) vehicles are a clean, low-emission technology and a solution for Europe’s air pollution crisis. A review of the latest data on particle pollution from CNG cars, vans, buses and trucks dispels these claims and shows the technology emits high levels of toxic pollutants. Download pdf

Maersk Seeks $150-a-Ton Carbon Tax on Shipping Fuel

The world’s largest container shipping line has called for a $150-a-ton carbon tax on shipping fuel that would drive up the costs for an industry that delivers 80% of world trade. A.P. Moller-Maersk A/S says such a levy would help bridge the price gap between fossil fuels that vessels consume today and greener alternatives that are currently much more expensive. Fuel costs would effectively almost double if the measure were imposed today because of how carbon dioxide emissions are counted. While such a shift would be challenging for shipowners at large, Maersk’s scale would enable the company to weather such a hike in what constitutes the industry’s single largest expense. Others, notably commodities trading giant Trafigura Group, have already called for such a tax. The issue is set to...

Mieux connaître la pollution des bateaux pour tenter de la réduire

https://www.franceinter.fr/mieux-connaitre-la-pollution-des-bateaux-pour-tenter-de-la-reduireC'est un enjeu majeur : les polluants émis par les navires sont responsables de plus de 50 000 décès par an en Europe. Or cette pollution aux particules fines est mal connue. Des chercheurs de l'école d'ingénieurs Estaca sont allés mesurer ces particules à bord d'un bateau qui relie Brest, Molène et Ouessant.

Comparison of the impact of ships to size-segregated particle concentrations in two harbour cities of northern Adriatic Sea

Highlights • High temporal resolution aerosol data were collected in two Adriatic port cities. • Shipping contribution to particle concentration of different sizes was investigated. • Contributions to nanoparticles were significantly larger compared to other sizes. • Relative contributions to nanoparticles were 7.4% in Venice and 1.8% in Rijeka. • Contributions to PM1, PM2.5 and PM10 were about 2% in Venice and <0.2% in Rijeka.
