From our friends at Classic-Sailing

In the UK we create 12 tonnes of carbon dioxide per person per year. (12000 kilos)
On average UK people weigh 72 kilos.
That’s 230 kilos per person per week, equal to 3.2 adults per week!.

When you are sailing you are creating about 53% less carbon than ashore.

You create carbon dioxide per person per week as follows –

* Infrastructure, this is shared amongst the whole ship’s compliment.
Home energy –there will be some small energy use even when you are not there.
Travel includes getting to and from your voyage. The more sailing you do and the less engine time you need – the better for the planet.

So!  Not only is sailing good for you, its a good way to enjoy the planet!
