Ships fitted with ‘cheat devices’ to divert poisonous pollution into sea
Shipping is a pretty dirty industry, because of fuel quality they use and the general lack of oversight in the middle of the ocean.<p>I was on the board of Corvus Energy (<a href="http://corvusenergy.com" rel="nofollow">http://corvusenergy.com</a>) while working in Norway, whose technology reduces CO2, SOx, NOx, and fuel consumption by up to 30%.  One installation was the equivalent of taking 10,000 cars off of the road.  Thankfully, there are developments in this space.<p>Bear in mind that shipping is also the most energy efficient form of bulk transportation (vs land or air).
