Shipping's CO2 Record Not So Shipshape, After All

Denmark may not be a huge player in the green global village, but it is a place that prides itself quite a bit on being...well, a little more eco than its Scandinavian neighbors. Traveling the tidy Danish countryside, the towering wind turbines spinning out clean electricity are your first clue to this pride. The Danes, especially in Copenhagen, seem years ahead in bike culture, organic food and clothing, and just in general in bringing their spare and friendly design aesthetic to much that they do.

So it was a major ego blow when the news hit that a single Danish company, the Moller-Maersk shipping conglomerate, creates as much carbon dioxide emissions from its operations (40 - 50 million tons) as the entire country of Denmark! Global shipping isn't yet counted as part of a nation's carbon footprint. As the International Maritime Organization tries to get a handle on shipping's actual emissions numbers, it is realizing they may be nearly 3 times larger than previous estimates, with big companies like Maersk playing a huge role in the 1.12 billion tons of CO2 emitted annually by shipping. Under EU pressure to work faster to clean up shipping's pollution, the IMO is meeting in Denmark this week and will work in part to figure out how to attribute CO2 emissions to individual nations.

P.S. That's Maersk's Emma container ship in the photo above - we wrongly reported she uses 200,000 liters of fuel a day. Thanks MacHaddock for the alert.

This will make the U.S. feel good about itself when Panama beats it for CO2 emissions. Their one of the main registries. My cars are registered in Canada but I have drove to the U.S and Mexico. Let the Panamanians buy off set like me.

This is what it sais on the page that is linked to in this article: "The company’s container ships used approximately 200,000 liters of oil or the equivalent of a small Danish city." That means all of them. Not just the one on the picture here. Shape this article up please.

the answer to this is easy (although not free)....new yachts and sailboats have been most recently built with the option to have their props powered not directly by a diesel engine, but via electric motors and batteries kept topped up by a dual purpose gen-set (generator operating at constant speed and peak efficiency that powers both the boat's systems and the batteries). this option allows the props to be independent of the diesel engine, which dramatically improves maneuverability. but the real benefit is that the emissions are cut to less than half since the engine never fluctuates in rpm. of course large container ships are designed for decades of use, so it's a slow process to get this technology into the fleets, and retrofits are not easy (i don't even know of a company that can do so on large ships - perhaps it's a business opportunity?). oh, and the newest cruise ships are using this technology as well, so it is viable for large vessels. and when we solve battery storage or fuel cell challenges, out goes the gen-set, and you've a zero-emission boat!

My chosen proffesion for the last 12 years is packaging design, reworking and re engineering.

And our biggest opportunities lie in shipping as a more efficient package usually costs more but the big cost out of South Africa is sea freight. This is where the big benefit is for all concerned. Looking at it from my newly found tree hugging perspective, We can continue to push the fact fact that they save on the amount of sea trips required per annum and the savings linked to that but also the massive carbon reduction per part per annum.
I recently read an article that enlightend me onthe fact that a ship has 40 times more power than a big truck but spits out in excess of 1200 trucks worth of emissions. I just wonder the amount of emmisions it would take to haul the 2 to 3000 plus containers along the roads of the coasts of our nations. If we can therefore push the kind of "electric" opportunities as mentioned in a previous comment then we will have hit 2 birds with one stone by packaging more efficiently. I have recently assisted with a presentation to the CD industry, where we have ways of changing to 100% reusable alternatives. And to the plastics these are 60% more efficient by makeing very small changes. The same with the Tobacco industry and also the Automotive and OEm industries around the world. If we take advantage of promoting the monetary savings by using less containers to move goods, we have the benefit as trea huggers of reducing carbon and its ugly friends.
Our opportunity is not that we may exist for generations to come but to allow the natural evolution to continue…for if man taken in his own desire for supremacy should remove himself from this existence, …Then we need to know that we have done all that we could to leave the planet in such a condition……that there is a ray of hope that she would find her way back to her former glory.

The article does not mention fuel consumption per day. I just looked at some stats for a large container ship that uses 40T/day of bunker oil. That is about 46,000 litres of fuel per day. I have no idea what the 200,000 litres figure in the article refers to.

It surely cannot be the total for 1000 ships daily fuel consumption or that would be about 200 litres per day each. Not likely, unless they are powered by an engine pulled from a VW Golf!
