Winds of change: the sailing ships cleaning up sea transport

Fairtransport ship Tres Hombres, which transports coffee for Shipped by Sail

Ethically minded entrepreneurs are turning back the clock to sweep the scourge of bunker fuel from the oceans

They fan out across the seas like a giant maritime dance, a ballet of tens of thousands of vessels delivering the physical stuff that has become indispensable to our way of life: commodities and cars, white goods and gas and grains, timber and technology.

But shipping – a vast industry that moves trillions of pounds-worth of goods each year – is facing an environmental reckoning.
Ships burn the dirtiest oil, known as bunker fuel; a waste product from the refinery process, literally scraping the bottom of the barrel, the crud in crude.
It’s so thick that you could walk on it at room temperature.

As a result, shipping is a major polluter – responsible for about 2.5% of global carbon emissions.
Not surprisingly, innovators are starting to wonder if there is another way.

“Around 90% of everything we consume [in Britain] spends some time at sea, so we urgently need to make the transportation of goods more sustainable,” says Will Templeman, an environmental scientist-turned-entrepreneur.

Templeman’s eureka moment came during a visit to the supermarket when he was agonising over the food miles in his trolley.
He wondered if it would be possible to transport things such as coffee and chocolate with zero emissions.
Then he remembered that this was how goods used to travel.
By sailing ship.

A quick online search revealed that a Dutch company was doing exactly that.
The owners of Fairtransport were inspired to revive sail cargo after witnessing at first hand the yellow smog caused by commercial vessels.
They restored two ships, a 70-year-old minesweeper renamed the Tres Hombres and a wooden ketch called Nordlys that dates back to 1873.
Templeman arranged to board the Tres Hombres, sailing from the Azores to the Netherlands.
“I was watching the ocean and it came like a ghost ship through the dawn mist. It looked like a pirate vessel. I was so excited.”

He dreamed of launching his own ship but realised that the first step was to make full use of the sailing vessels already in service.
He set up as a broker and together with his business partner, Will Adeney, went in pursuit of products to sell.
They found their perfect olive oil in Portugal and arranged to have it shipped to Devon on board the Nordlys.
They later sourced coffee beans in Colombia, and shipped them to Europe on the Tres Hombres.
Their business, Shipped by Sail, was born.

It joined a growing network of brokers and sailors passionate about transporting goods by wind power.
The next step: to boost demand for this kind of transportation.
“Consumers already understand organic produce and fair trade, and the next step is clean transport,” says Cornelius Bockermann, who founded Timbercoast, a German sail cargo company that has restored a schooner from 1920, and is now refitting a second.

Clean transport is the missing link, as many so-called sustainable or ethical goods are currently carried on ships that pollute the air and sea.
The perfect example of this is plant-based meat, shipped around the world from California.

British couple Marcus and Freya Pomeroy-Rowden built their ship, the Grayhound, as a replica of an 18th-century lugger, and carry cargo between the UK and France, bringing West Country ale to Brittany and French wine to Cornwall.
They supply small businesses along the way, for example providing wines to Dibble & Grub on the Isles of Scilly.
The couple enjoy the lifestyle of spending months at sea, making a living, while making a difference.
Marcus says they’re bringing trade back to a human scale.
“We’re taking quality products and transporting them direct to a distributor.
We can understand and explain the whole chain for our products, from manufacture to the table.”

In France, TransOceanic Wind Transport has developed a labelling system with a voyage number, allowing the customer to see how products reached them.

Broker Alex Geldenhuys launched New Dawn Traders in the UK about six years ago and is still developing her “voyage co-op” model, bringing together farmers, ships and buyers.

 

Geldenhuys has been inspired by local food communities and vegetable box schemes and wants to extend that movement overseas, building relationships with distant farmers to bring ethically produced, high-quality produce to the UK with a carbon footprint that is close to zero.
She is seeking “port allies” to promote the idea in coastal communities, encouraging customers to pre-order products from the ships and turning collection events at the docks into celebrations of the whole process.

A few weeks ago a French schooner, De Gallant, sailed into Bristol laden with produce from Portugal; the first time a tall ship had brought cargo to the city for decades.
It was an emotional moment for Geldenhuys and the climax of years of work.
“It was beautiful to watch her sailing in under the suspension bridge,” she says.
Local people milled around the ship, sampling olive oil, almonds and wines.

Geldenhuys acknowledges that currently she can only deliver to her customers twice a year.
Templeman says: “Restaurants and other businesses need a regular supply to be reliable.
So we’re warehousing goods.”
Olive oil on De Gallant was transported by electric van to a restaurant in Bristol.

The biggest challenge for sail cargo is scale.
There are currently only a few small ships operating.
Most companies feel that the time is ripe for expansion and have plans to build larger vessels.
One of the founders of Fairtransport, Jorne Langelaan, has set up a new venture called EcoClipper to facilitate emission-free shipping worldwide.
He is planning for more sailing ships running more routes more frequently.


In Costa Rica, Canadian Danielle Doggett is building a sailing ship called Ceiba, which looks set to become the largest in the world.
The project uses tropical trees that have fallen in storms, and more trees are planted as the building proceeds.
Ceiba will be able to carry 250 tonnes of cargo (Tres Hombres and De Gallant take 35 tonnes), which is equivalent to around 10 containers.
Yet this is still much smaller than the historic tea clippers, such as the Cutty Sark, and dwarfed by the largest modern container ships, which can carry more than 20,000.

The shipping industry knows that change is on the horizon.
From next year new regulations will further limit sulphur oxide emissions from ships.
The International Maritime Organization has announced its ambition to halve greenhouse gas emissions by 2050.
The world’s largest shipping company, Maersk, has gone further, pledging to be carbon-neutral by 2050.

Templeman acknowledges that the largest companies want to make their fleets more energy-efficient, but points out: “We’re coming from the opposite direction and offering emission-free shipping right now, while asking what sail shipping could have been with another 100 years of development.”
Marcus Pomeroy-Rowden adds: “We’re waving a flag to say the world can’t carry on as it is.
We’re also showing what can be done in a different way.”

Bockermann stresses that industrial shipping is only cheap because it externalises the environmental costs.
“What you normally pay a shipping company doesn’t account for the damage to the environment, pollution or health.
Our costs are comparatively high but if you had to pay for the damage of conventional shipping then we wouldn’t seem expensive.”

Geldenhuys adds: “We might not be the solution to how everything is shipped in the world but we can make people think about what they’re buying and how it’s getting here.
It’s easy to feel overwhelmed and helpless.
But we can all do something.
We don’t need one solution to everything, we need a thousand solutions that can exist simultaneously.”

Ocean acidification can cause mass extinctions, fossils reveal

From The Guardian

Carbon emissions make sea more acidic, which wiped out 75% of marine species 66m years ago

Ocean acidification can cause the mass extinction of marine life, fossil evidence from 66m years ago has revealed.

A key impact of today’s climate crisis is that seas are again getting more acidic, as they absorb carbon emissions from the burning of coal, oil and gas.
Scientists said the latest research is a warning that humanity is risking potential “ecological collapse” in the oceans, which produce half the oxygen we breathe.

The researchers analysed small seashells in sediment laid down shortly after a giant meteorite hit the Earth, wiping out the dinosaurs and three-quarters of marine species.
Chemical analysis of the shells showed a sharp drop in the pH of the ocean in the century to the millennium after the strike.

This spike demonstrated it was the meteorite impact that made the ocean more acidic, effectively dissolving the chalky shells of many species.
Large-scale volcanic activity was also considered a possible culprit, but this occurred over a much longer period.

The oceans acidified because the meteorite impact vaporised rocks containing sulphates and carbonates, causing sulphuric acid and carbonic acid to rain down.
The mass die-off of plants on land after the strike also increased CO2 in the atmosphere.

“We show ocean acidification can precipitate ecological collapse,” said Michael Henehan at the GFZ German research centre for geosciences in Potsdam, who led the study.
“Before we had the idea, but we did not have the empirical proof.”

The researchers found that the pH dropped by 0.25 pH units in the 100-1,000 years after the strike.
It is possible that there was an even bigger drop in pH in the decade or two after the strike and the scientists are examining other sediments in even finer detail.

Henehan said: “If 0.25 was enough to precipitate a mass extinction, we should be worried.” Researchers estimate that the pH of the ocean will drop by 0.4 pH units by the end of this century if carbon emissions are not stopped, or by 0.15 units if global temperature rise is limited to 2C.
Henehan said: “We may think of [acidification] as something to worry about for our grandchildren.
But if it truly does get to the same acidification as at the [meteorite strike] boundary, then you are talking about effects that will last for the lifetime of our species.
It was hundreds of thousands of years before carbon cycling returned to normal.”

The research, published in the journal Proceedings of the National Academy of Sciences, analysed sediments that Henehan encountered by chance, during a conference field trip in the Netherlands.
The sediments, which straddle the moment of the impact, lie in caves that were used by people hiding from the Nazis during the second world war.
“It was so lucky,” said Henehan.

The rocks contained foraminifera, small-shelled marine organisms.
“In the boundary clay, we managed to capture them just limping on past the asteroid impact.
But you can see their shell walls were much thinner and poorly calcified after the impact,” he said.

It was the knock-on effects of acidification and other stresses, such as the “nuclear winter” that followed the impact, that finally drove these foraminifera to extinction, he said: “You have the complete breakdown of the whole food chain.”
He said oceans also faced additional stresses today, from global heating to widespread pollution, overfishing and invasive alien species.

When the Chicxulub asteroid landed in what is today Mexico, it didn't just extinguish the dinosaurs. It devastated life in the oceans, too.

Phil Williamson, at the University of East Anglia, who was not involved in the research, said: “It is relatively easy to identify mass extinction events in the fossil record, but much harder to know exactly what caused them. Evidence for the role of ocean acidification has generally been weak, until now.”
He said caution was needed in making the comparison between the acidification spike 66m years ago and today: “When the asteroid struck, atmospheric CO2 was naturally already much higher than today, and the pH much lower.
Furthermore, large asteroid impacts cause prolonged darkness.”
Williamson added: “Nevertheless, this study provides further warning that the global changes in ocean chemistry that we are currently driving have the potential to cause highly undesirable and effectively irreversible damage to ocean biology.”

Henehan said the generally lower ocean pH 66m years ago might have made shelled organisms more resilient to acidification.
“Who knows if our current [marine] system is as well set up to cope with sudden acidification?”
