Daily Mail: How 16 ships create as much pollution as all the cars in the world

from Fred Pearce of the Daily Mail:

Award-winning science writer Fred Pearce – environmental consultant to New Scientist and author of Confessions Of An Eco Sinner – reveals that the super-ships that keep the West in everything from Christmas gifts to computers pump out killer chemicals linked to thousands of deaths because of the filthy fuel they use.

We’ve all noticed it. The filthy black smoke kicked out by funnels on cross-Channel ferries, cruise liners, container ships, oil tankers and even tugboats.

It looks foul, and leaves a brown haze across ports and shipping lanes. But what hasn’t been clear until now is that it is also a major killer, probably causing thousands of deaths in Britain alone.

As ships get bigger, the pollution is getting worse. The most staggering statistic of all is that just 16 of the world’s largest ships can produce as much lung-clogging sulphur pollution as all the world’s cars.

Because of their colossal engines, each as heavy as a small ship, these super-vessels use as much fuel as small power stations.

But, unlike power stations or cars, they can burn the cheapest, filthiest, high-sulphur fuel: the thick residues left behind in refineries after the lighter liquids have been taken. The stuff nobody on land is allowed to use.

Thanks to decisions taken in London by the body that polices world shipping, this pollution could kill as many as a million more people in the coming decade – even though a simple change in the rules could stop it.

There are now an estimated 100,000 ships on the seas, and the fleet is growing fast as goods are ferried in vast quantities from Asian industrial powerhouses to consumers in Europe and North America.

The recession has barely dented the trade. This Christmas, most of our presents will have come by super-ship from the Far East; ships such as the Emma Maersk and her seven sisters Evelyn, Eugen, Estelle, Ebba, Eleonora, Elly and Edith Maersk.

Each is a quarter of a mile long and can carry up to 14,000 full-size containers on their regular routes from China to Europe.

Emma – dubbed SS Santa by the media – brought Christmas presents to Europe in October and is now en route from Algeciras in Spain to Yantian in southern China, carrying containers full of our waste paper, plastic and electronics for recycling.

But it burns marine heavy fuel, or ‘bunker fuel’, which leaves behind a trail of potentially lethal chemicals: sulphur and smoke that have been linked to breathing problems, inflammation, cancer and heart disease.

James Corbett, of the University of Delaware, is an authority on ship emissions. He calculates a worldwide death toll of about 64,000 a year, of which 27,000 are in Europe. Britain is one of the worst-hit countries, with about 2,000 deaths from funnel fumes. Corbett predicts the global figure will rise to 87,000 deaths a year by 2012.

Part of the blame for this international scandal lies close to home.

In London, on the south bank of the Thames looking across at the Houses of Parliament, is the International Maritime Organisation, the UN body that polices the world’s shipping.

For decades, the IMO has rebuffed calls to clean up ship pollution. As a result, while it has long since been illegal to belch black, sulphur-laden smoke from power-station chimneys or lorry exhausts, shipping has kept its licence to pollute.

For 31 years, the IMO has operated a policy agreed by the 169 governments that make up the organisation which allows most ships to burn bunker fuel.

Christian Eyde Moller, boss of the DK shipping company in Rotterdam, recently described this as ‘just waste oil, basically what is left over after all the cleaner fuels have been extracted from crude oil. It’s tar, the same as asphalt. It’s the cheapest and dirtiest fuel in the world’.

Bunker fuel is also thick with sulphur. IMO rules allow ships to burn fuel containing up to 4.5 per cent sulphur. That is 4,500 times more than is allowed in car fuel in
the European Union. The sulphur comes out of ship funnels as tiny particles, and it is these that get deep into lungs.

Thanks to the IMO’s rules, the largest ships can each emit as much as 5,000 tons of sulphur in a year – the same as 50million typical cars, each emitting an average of 100 grams of sulphur a year.

With an estimated 800million cars driving around the planet, that means 16 super-ships can emit as much sulphur as the world fleet of cars.

CNN: Ship emissions blamed for worsening pollution in Hong Kong

by Grigory Kravtsov, reporting for CNN:

Smog is a common sight in Hong Kong, with the amount of polluted days increasing by 28 percent to 303 so far this year.

Hong Kongers would be quick to point the finger at Chinese factories across the border. Yet, research is increasingly indicating that the problem is much more localized, coming from emissions produced by shipping.

What we know in Hong Kong is that up to 50% of pollution [locally produced] sources come from marine vessels,” said Gina McCarthy, administrator at the U.S. Environmental Protection Agency.

Smog levels within the city of over 7 million reached hazardous levels earlier this week, with particles in one urban area, Sham Shui Po hitting a PM2.5, hitting 91.7 micrograms per cubic meter of air. Anything above 71 is classified as “very dangerous” according to the World Health Organization guidelines.

Maritime pollution in Hong Kong is blamed for the most sulfur dioxide-related deaths within the region. According to a recent report jointly compiled by the Civic Exchange and The University of Science and Technology, Hong Kong saw 385 deaths caused by the hazardous chemical, for which shipping is to blame.

The city lacks regulations in tackling maritime pollution, as there is no legislation or requirements for shipping companies to switch to cleaner fuel when entering Hong Kong waters.

Lack of Emissions Control Area in HK waters will continue to leave Hong Kong blanketed in smog

Less than a week after favourable weather cleared the skies of Hong Kong, the city is covered again in particles. It has become a common refrain for city officials to sing of their achievements in switching out diesel engines from the roads, and after that for Legco members to debate to no end as to how (un)successful their measures have been in improving the city’s air quality.

It is also commonly known, albeit with less attention paid, that cargo ships – especially ocean-going vessels – are a major contributor to pollutants as they move through the waters of Hong Kong. In addition to Hong Kong’s own Kwai Chung terminal, ships docking at Shenzhen’s Yantian and Shekou terminals pass through channels east and west of Hong Kong respectively, meaning Hong Kong bears the brunt of the emissions whichever way the prevailing winds blow.

Thus far, Hong Kong’s policymakers have only implemented a weak policy – incentivising ships docking at Kwai Chung to switch to cleaner fuels when moving in Hong Kong, transitioning into a compulsory requirement by Sep 2014. Meanwhile, there are already complaints that this would ‘hurt competitiveness’ of the Kwai Chung terminal in comparison with Shenzhen’s terminals (of which Hong Kong’s Hutchison Whampoa, and the Wharf, are shareholders).

The situation can be greatly improved if Hong Kong officials can push for the implementation of an Emissions Control Area, which will effectively make the same clean fuel requirements for Shenzhen’s terminals. This may call for cross-border co-operation between policymakers in order for the policy to be strictly enforced, but if Hong Kong officials wish to display some real work done, there can be no better opportunity.

Clear The Air has prepared a brief document on this issue.

SCMP: Shipping lines say proposed EU emissions rules will hamper their operations

from Anita Lam of the SCMP:

Shipping lines are fighting a new environmental regulation that they said will not only lead to stringent control over their operations but will also pave the way for a carbon trading policy resembling the one that sparked controversy in the aviation sector.

The EU needs a better examination of proposals to impose emissions limits on shipping, a major contributor to greenhouse gas emissions. (Guardian)

To curb greenhouse gas emissions produced by the maritime trade – expected to more than double by 2050 from 1 billion tonnes per year at present – the European Commission is seeking to legislate a draft rule it made in late June requiring mandatory provision of data from carriers on their vessels’ fuel type, fuel efficiency and payload (the total weight of fuel and cargo).

Kamar Zaman, a veteran analyst at Drewry Shipping Consultants, said it is infeasible if not impossible to ask a carrier to weigh all its containers.

“How will you weigh those boxes, which come in millions? What kind of disruption will it cause to daily operations, and who is going to pay for the cost?” Zaman said.

There are many firms and government bodies that calculate vessel emissions with readily available data provided by ship manufacturers and carriers.

But the European Union wants a closer look, in the hope of imposing operational guidelines for the trade and ultimately an emissions trading scheme like the one it imposed on the aviation sector, which requires airlines that produce more carbon dioxide to buy credits from those that produce less.

The shipping industry worldwide has been raising the alarm about the possible changes.

Christopher Koch, president and chief executive of the Washington-based World Shipping Council, said it is quite impossible for carriers to comply with standards that regulate how much fuel they use, how fast they sail a ship and how they maintain it, which is like “teaching drivers how to drive”.

There are many factors that govern fuel use and vessel speed, he said, including the weather, the need to meet schedules and outrunning pirates.

Shipping lines have already been adapting to methods such as slow steaming, forming alliances to share resources and using new, fuel-efficient vessels to save fuel and cut costs in the wake of the downturn in the industry last year.

The Hong Kong Shipowners Association said there is a limit to how much fuel you can save.

“You might be able to drive your car more efficiently,” said Arthur Bowring, the group’s managing director.

“But how can you drive it to increase efficiency by a set amount every year?”

Until now, shipping has been the only form of transport excluded from the EU’s strategy to cut emissions, but Zaman said that was only because it would be very difficult to identify the party that should bear the extra costs.

“Unlike aviation, where the airline is clearly responsible, there could be up to 20 consignees for one vessel,” Zaman said, referring to the fact that a shipowner may charter the vessel to a carrier, which then commissions a third party to operate the ship, the space in which is usually shared by several carriers.

The EU draft is expected to enter into force in July 2015, although the first reporting period for carriers would begin in January 2018.

Shipping lines complain about expensive clean fuel requirements

Ocean-going vessels, burning bunker fuels with 2.75-4% sulphur content, is a major contributor of air pollutants to Hong Kong. Prevailing winds bring sulphur particles into the ‘urban canyons’ of Hong Kong, where the concentration of particles are increased, posing a huge health hazard to Hong Kong residents.

Shipping lines are now complaining that the requirements imposed by the Hong Kong government to use cleaner fuels will increase their cost of business, and demands that the government extends a subsidy scheme that incentivises the use of cleaner fuels (the scheme does not end until Sep 2015). Alarmist warnings about ‘competitiveness’ with Shenzhen are being sent out, aiming to panick and pressurize the authorities to provide more incentives for doing what is right, even though they can share the extra costs with their clients as per usual business practices.

Of note is that Hong Kong is ‘the only Asian city to impose such a requirement’. Hong Kong should not step backwards from the rare occasion of being the lead in an environmentally-friendly policy, with developing economies increasingly adopting environmental technologies and policies ahead of Hong Kong.

from Anita Lam of the SCMP:

Ships calling at Hong Kong will face higher costs when legislation requiring vessels to switch to cleaner marine fuel upon berthing is passed next year.

Some carriers may, as a result, switch to neighbouring ports in Shenzhen.

To prevent this, shipowners said, the government should consider extending a scheme that subsidises shipping lines – many of which are expected to suffer losses this year – for the extra cost of the clean fuel.

However, a government official said, an extension is unlikely.

AirClim: Shipping air pollution costs €60 billion per year

From Christer Ågren of Air Pollution & Climate Secretariat:

Total health-related costs in Europe caused by air pollutant emissions from international shipping are expected to increase from €58 billion to €64 billion between 2000 and 2020.

The total health-related costs of air pollution in Europe are calculated to have been more than €800 billion per year at the pollution levels of year 2000. This figure is estimated to decrease to €537 billion in 2020, provided that EU countries reduce their emissions from land-based sources in line with what is needed to achieve the environmental targets of the EU’s 2005 Thematic Strategy on Air Pollution, and provided that the sulphur emission standards for international shipping are complied with.

Air pollution is estimated to have been responsible for around 680,000 premature deaths in the whole of Europe in the year 2000, a figure that is expected to come down to approximately 450,000 in 2020.

Comparing the health impacts from shipping with those from land-based sources shows that in the year 2000 emissions from international shipping were responsible for an estimated seven per cent of the total health damage from air pollution in Europe, and that its share will increase to twelve per cent by 2020.

The number of annual premature deaths in Europe linked to air pollution from international shipping is estimated to increase from 49,500 to 53,400 between 2000 and 2020.

These figures come from a Danish study1 using the EVA (Economic Value of Air pollution) computer model. The research project aims to map the true costs of damage caused by air pollutant emissions from various sectors. Different scenarios assessing the human health impacts and associated external costs from different emission sectors have been investigated for the years 2000, 2007, 2011 and 2020 (see Table).

Table: Estimated total number of annual premature deaths in Europe caused by different emission sources

2000 2007 2011 2020
All sources 681,100 575,500 572,600 450,000
International shipping 49,500 48,300 46,000 53,400
Int. shipping in the North Sea and Baltic Sea 20,400 16,200 14,100 13,200

Air pollutant emissions from ships operating in the North Sea and the Baltic Sea were responsible for annual health damage in Europe valued at €22 billion at the emission levels of year 2000. By 2020, this figure is expected to come down to €14.1 billion, as a result of implementation of the stricter ship fuel sulphur standards agreed by the International Maritime Organization (IMO) in 2008 (see Box).

International ship emission regulations

The International Maritime Organization (IMO), under ANNEX VI of MARPOL 73/78 (the International Convention for the Prevention of Pollution from Ships), has adopted controls on sulphur in marine fuels.

The global fuel sulphur limit is currently 3.50% and will be lowered to 0.50% by 2020 (or possibly 2025, subject to a review in 2018). In specially designated sulphur emission control areas (SECAs), the current limit is set at 1.00% sulphur. It will be tightened to 0.10% by 2015.

Through the revision of the EU’s sulphur-in-fuels directive (2012/33/EU), which was finalised last year, these sulphur standards are part of binding EU legislation.

In Europe there are currently only two existing SECAs: the Baltic Sea and the North Sea (including the English Channel). Most of the coastal waters – within 200 nautical miles of the coast – of the USA and Canada have been designated as “combined” ECAs for both SO2 and NOx.

It should be noted that exhaust gas cleaning systems (e.g. scrubbers) that achieve equivalent sulphur emission reductions may be used as an alternative to low-sulphur fuels to fulfil the sulphur requirements.

However, since these stricter fuel standards apply only in designated Sulphur Emission Control Areas (SECA), and the Baltic Sea and the North Sea so far are the only such areas in Europe, and ship traffic overall is expected to continue to increase, the total health-related costs in Europe of international ship traffic are expected to increase from €58.4 billion in the year 2000 to €64.1 billion in 2020.

In the intermediate years (2007 and 2011), smaller decreases in the health damage from ship pollution occurred as a result of stricter sulphur standards in the SECA area. The subsequent increase up to 2020 results from an overall projected increase in ship traffic worldwide.

It is noted by the authors that a similar study performed by the US Environmental Protection Agency estimated that by 2020 air pollution from shipping would still cause 21,000 annual premature deaths within the USA, with related health costs amounting to USD47–110 billion.

Specifically for Denmark, it is estimated that the total annual health-related air pollution damage amounted to €4.5 billion in year 2000. By 2020, this figure is expected to come down to €2.5 billion.

Air pollutant emissions from international shipping in the Baltic Sea and the North Sea are responsible for health damage in Denmark valued at more than €620 million per year (year 2000), decreasing to €360 million in 2020. The authors conclude that the SECA regulation that limits the sulphur content in ship fuel to a maximum of 0.1 per cent as from 2015, is expected to significantly reduce the external costs, and that “a similar regulation of international ship traffic in the whole world would have a significant positive effect on human health.”

It is however noted that the health impacts from ship emissions in the SECAs will remain significant after 2015. The reason being that the emissions of nitrogen oxides (NOx) from ship traffic are not regulated by the SECA standard, and in the scenario used, NOx emissions from international shipping are therefore expected to continue to increase more or less in line with the projected increase in shipping activities.

Policy change driven by an AIS-assisted marine emission inventory in Hong Kong and the Pearl River Delta

http://adsabs.harvard.edu/abs/2013AtmEn..76..102N

Abstract

A new exhaust emission inventory of ocean-going vessels (OGVs) was compiled for Hong Kong by using Automatic Identification System (AIS) data for the first time to determine typical main engine load factors, through vessel speed and operation mode characterization. It was found that in 2007, container vessel was the top emitting vessel type, contributing 9,886, 11,480, 1,173, 521 and 1166 tonnes of SO2, NOx, PM10, VOC and CO, respectively, or about 80%-82% of the emissions. The top five, which also included ocean cruise, oil tanker, conventional cargo vessel and dry bulk carrier, accounted for about 98% of emissions. Emission maps, which add a new spatial dimension to the inventory, show the key emission hot spots in Hong Kong and suggest that a significant portion of emissions were emitted at berth. Scientific evidence about the scale and distribution of ship emissions has contributed in raising public awareness and facilitating stakeholder engagement about the issue. Fair Winds Charter, the world’s first industry-led voluntary emissions reduction initiative, is a perfect example of how careful scientific research can be used in public engagement and policy deliberation to help drive voluntary industry actions and then government proposals to control and regulate marine emissions in Hong Kong and the Pearl River Delta region.
