A cruise ship's emissions are the same as 1 million cars: report

A luxury cruise vacation may sound like a perfect dream holiday, but a German environmental organization says that in terms of environmental impact, the industry is an absolute nightmare.

​Nabu has just released its annual report on cruise ship pollution. It looked at dozens of vessels travelling in Europe, and decided not to recommend any of them.

Dietmar Oeliger is one of the authors and head of transport policy at Nabu. He spoke with As it Happens host Carol Off from Berlin. Here is part of their conversation.

Dietmar Oeliger is head of transport at Nabu, a German environmental association. He co-authored a study that gives a failing grade to the cruise ship industry's environmental management. (Twitter)

Were there really no cruise ships that you looked at that you could recommend?

Unfortunately not. We found out that pollution from the cruise ship industry is still massive, even despite that they claim newer vessels are clean and green. We made measurements at quite a few cruise lines, and it proves that nearly all of them, their attitude to the environment is still poor.

Why are they so bad for the environment?

All of them run on the dirtiest fuel you can imagine. It's heavy fuel oil, it's quite toxic. It's a residual of the petrol industry, and it contains a lot of dirty stuff.
'The cruise companies know what they are doing, and they know about the problems. But still, they order new ships and don't install emission abatement systems.'
- Dietmar Oeliger

And on top of that, nearly all of the cruise ships don't have a catalyst or a particulate filter, [like] trucks and cars. That, altogether, sums up to really poor environmental situations.

The report says that a mid-sized cruise ship can use as much as 150 tonnes of fuel each day, which emits as much particulate as one million cars. Is that right?

That's correct. And the reason for this is that their engines run 24/7. Even if they're in the ports, they have to keep running their engines, because it's not only a transport mode, it's a hotel facility. They have a spa on board, restaurants ... and that needs a lot of energy — more or less the same energy a mid-sized city needs.

What does it mean for those who are actually cruising around on the boats themselves?

Unfortunately, we were not allowed as an organization to have measurements on board. Therefore, we helped two major TV stations from Germany and one from France to go undercover on board and take measurements with our help. It showed that the amount of emissions that passengers breathe on board is more than twenty times higher than on a main road with a lot of pollution.

You write in the report that the cruise ship companies "show contempt for their customers." What do you mean by that?

The cruise companies know what they are doing. And they know about the problems that result from their emissions.

But, still, they order new ships and don't install emission abatement systems on their ships. Most of the newest ships, that cost about a billion dollars, they don't even have an emission abatement system that would cost about a million. I would say this is really irresponsible.

This is a competitive industry, they're all cutting costs where they can. So is it really the companies themselves that should be making these changes, or should this be legislated?

Of course, legislation would be the most effective way. But legislation is made by the International Maritime Organization (IMO), which is located in London. It's an organization where countries like Liberia, Panama or Greece have a strong position.

And that is because most of the ships are flagged in these states. These countries are very often not interested in environmental regulation and strong enforcement. And that's why we say we can't wait for IMO. We have to be much faster.

Would you recommend to people not to take cruises?

Well, I wouldn't go on a cruise ship for many reasons. I would not say that people shouldn't go. If it's a once-in-a-lifetime dream for them, if they saved a lot of money to do it, that's fine for me. But if you have the choice to take this or that ship, then take one that is doing quite well in terms of environmental regulation.

Ovde je poenta što se truju putnici na kruzerima. :D A i što vlasnici neće da instaliraju katalizatore i filtere koji koštaju milion dolara, iako to ne bi ni osetili jer brod košta milijardu.

New diesel cars no better for environment than gasoline counterparts, German officials say
http://www.autonews.com/article/2017092 ... unterparts

BERLIN -- New diesel cars do not produce less of the environmentally damaging carbon dioxide than gasoline vehicles, a group of newspapers cited the German Transport Ministry as saying on Wednesday, in a potential further headache for the auto sector.

The automotive industry is Germany's biggest exporter and employs more than 800,000 people. It was plunged into crisis two years ago when Volkswagen admitted to cheating U.S. diesel emissions tests.

The Funke group of newspapers cited an answer from the Transport Ministry to an inquiry from the opposition Greens as saying diesel cars registered in 2016 emitted 128 grams of carbon dioxide per kilometer on average compared with 129 grams from new petrol cars.

The emissions difference has been similar for ten years but the amount of CO2 has fallen, it said, adding that one reason the carbon dioxide values were almost identical was because diesel cars were heavier and had higher power.

The Transport Ministry did not immediately respond when contacted by Reuters.

"It's a myth that diesel helps protect the climate," Stephan Kuehn, transport expert for the Greens in Germany's lower house of parliament, told the Funke newspapers.

"Diesel motors squander the theoretical advantages they could bring for the environment by often being built into heavy, high-powered cars," he added.

Dizelaši za istu snagu emituju malo manje CO2, jer manje i troše. Ali CO2 nije otrovan već samo (navodno) utiče na efekat staklene bašte. Sve je to potpuno beznačajno u odnosu na druge užase koje dizel motori ispuštaju više nego benzinski - sumporne i azotne okside, kao i čvrste čestice ugljenika u obliku čađi. Ima i jedna stvar koju niko ne pominje, a to je povećana buka u odnosu na benzince. Nekada je u gradovima "čekićanje" poticalo samo od autobusa i kamiona, a sada je 70-80 % automobila u Evropi na dizel pogon. To je posebno problem u zemljama kao što je naša, gde ima mnogo starijih vozila.

Buka je mozda veca, ali nije toliko znacajna. Svaki stariji GSP autobus ce, svojim brundanjem, zujanjem, 'prdenjem', zaseniti i roj njaglasnijih dizel auta.

He, he, autobusi.
Pre neki dan, Brankovom se penje Ikarbus, iza njega dimna zavesa, crna, a iznad ozonska rupa, velika.

Rekao bi čovek: ništa neuobičajeno?!

Međutim, natpis na busu je: EKO1

Ubacili ga umesto elektrobusa. Baš su našli zamenu...

Sales of gasoline-powered cars overtake diesels in Europe
http://europe.autonews.com/article/2017 ... -in-europe

LONDON -- Sales of gasoline-powered cars have overtaken diesel in the first half for the first time since 2009, industry association ACEA said.

The shift saw gasoline car sales rise by nearly 10 percent from the first half of 2016, compared with an approximate 4 percent drop in diesel car sales, the group said in a statement on Friday.

Diesel's market share fell to 46.3 percent of new-car registrations from 50.2 percent in the first half of last year. In absolute numbers, 152,323 fewer diesel cars were sold, ACEA said.

The drop was offset by an increase in gasoline car sales which accounted for 48.5 percent of sales, up from 45.8 percent. This translates into 328,615 extra gasoline cars sold year-on-year.

Sales of "alternative" vehicles - hybrid, electric, LPG (liquefied petroleum gas) and natural gas-powered ones - also rose by more than 35 percent to account for 5.2 percent of total car sales.

The mayors of Paris and Athens have said they plan to ban diesel-engine cars in city centers by 2025 because of their high NOx emissions, while France is also making plans to reverse favorable tax treatments for diesel. Some expect other European governments to follow suit.

Even car manufacturing centers Stuttgart and Munich have mulled diesel engine bans.

ACEA cautioned the shift to gasoline engines could make it tougher for Europe to meet CO2 reduction targets. "Policy makers need to be aware that a sudden shift from diesel technology to petrol will lead to an increase in CO2 emissions," ACEA Secretary General Erik Jonnaert said.

Jonnaert also called on governments to do more to promote "alternative" cars. Sales of hybrid electric vehicles rose 58 percent in the first half, and electric-car sales rose by 37 percent, but the groups still account for just 2.6 percent and 1.3 percent, respectively, of total car sales.

"More needs to be done to encourage consumers to buy alternatively-powered vehicles, for instance by putting in place the right incentives and deploying recharging infrastructure across the EU," Jonnaert said.

Dizel je izgleda mnogo jeftiniji kroz deo Evrope kroz koji sam prošao. Ima uvek dve vrste dizela minimum na pumpi, dok benzin bude 95 i ne baš tako često 98. 100tku sam video u Sloveniji i navodno poneki Agip ga ima.

Moj utisak je da tamo benzinaca ima minimalno.

Ovde u DE ima uglavnom samo jedna vrsta dizela, a Supera dve ili tri.

Porsche seeks 200 million euro damages from Audi over dieselgate: Bild
http://www.reuters.com/article/us-audi- ... CB1XI?il=0

BERLIN (Reuters) - Volkswagen’s (VOWG_p.DE) Porsche brand is seeking 200 million euros ($234 million) in damages from its luxury stablemate Audi over costs related to manipulated diesel engines, Bild newspaper reported on Friday.

Porsche’s management delivered the claim in written form to counterparts at Audi, the newspaper said without citing its source.

Audi (NSUG.DE) admitted in November 2015 that its 3.0 liter V6 diesel engines used in about 80,000 VW, Audi and Porsche models were fitted with an auxiliary device deemed illegal in the United States.

The German government earlier this year ordered a recall of Porsche’s Cayenne sport-utility vehicle (SUV) and prohibited registrations of the model’s diesel version.

Porsche wants compensation from Audi for the costs of the retrofits, legal counseling and customer measures, Bild said.

A spokesman for Porsche said VW group-internal issues were not meant for public discussion, without elaborating. Audi declined comment and referred inquiries to Porsche.
