""Environmental measures don't have to cost money," Winkler said.
This is a concept with some truth to it.
The Prague Statement and the Porter Hypothesis both support this view.
It declares: "Good environmental regulation helps reduce costs
for industry and business"
There is also the "Porter Hypothesis" (In a 1995 debate on the Porter Hypothesis—the idea that tougher
environmental standards can make companies more innovative and,
ultimately, more profitable—Porter and van der Linde [13] argue
that economists are locked into a “static mindset that environmentalism
is inevitably costly.”)
It is noticeable that at this time there are many approaches to lowering emissions that include the simple concept of better fuel efficiency.
For example, new hull coatings (Jotun?) route planning and reduced speed. The last is of perticular interest since tthe Port Of Los ANgeles has imposed a "voluntary" but arbitary speed limit. Now simply halving the speed could simply mean the vessel is in the area for twice as long and takes twice as long to produce the same amount of pollution and of course, since all vessels are there for longer, they collectively emit the same amount of pollution as before only now the shipping is more dense. However, there have been some impressive savings posted in the press in recent months, one of which suggests that by running at 12 knots, oil tankers could save as much as 50% of the fuel used.
Earlier studies by a Canadian Ferry company simply using accurate fuel flow measurements, showed as much as 10% fuel reductions but by simply throttling back a little bit and using the fuel efficicency information to learn how to take best advantage of the prevailing conditions. These systems are now commercially available providing whellhouse displays of real time fuel efficiency such that even a 1/4knot speed reduction can produce significant savings without significantly affecting operations (the data is logged automatically helping meet ISO 14000 objectives). In fact this idea has more recently been discussed by Tee Kay Shipping and others.
A brief search of the internet will reveal a number of such solutions including "FUSION" from Flow Technology Inc. which was originally aimed at offshore vessels but which is also suited to deep sea vessels.
But the sense of the article, and generally, is that the industry, save a few exceptions, seems reluctant to pursue these solutions. This was also, I believe, the sense from SEAaT, that the industry enthusiasm for any of the Market based mechanisms, especially as they could assist with scrubber technology, seems soemwhat absent. Market based mechanisms is not just emissions trading. It can include a whole range of financial incentives to encourage more efficient shipping and lowered emissions. Both the IMO and the EU (see the NERA report to the EU) are prepatred to consider market based mechanisms but where is the industry response? So by being more fuel efficienct, for example, not only would the vessel incur lower fuel costs but could also generate emissions credits to traade with less efficient vessels or gain lower port dues for example.
