The sailing ship is a textbook example of sustainability. For at least 4,000 years, sailing ships have transported passengers and cargo across the world’s seas and oceans without using a single drop of fossil fuels. If we want to keep travelling and trading globally in a low carbon society, sailing ships are the obvious alternative to container ships, bulk carriers, and airplanes.

The EcoClipper500 has a carbon footprint of 2 grammes of CO2 per tonne-kilometre, which is five times less than the carbon footprint of a container ship.

I expected the difference to be so much bigger than this. I knew steel was heavy on emissions, but I didn't think it was that bad. It really demonstrates how important it is to curb steel production and use less damaging materials, but that's going to be a really sharp cliff for us to climb.

Good point. Yeah, there's some useful information here and throughout the website ( which runs on solar power ) . It will definitely take time but that cliff will only get steeper if we don't start climbing it now.
