Carbon offsets for private jet travel have become a fairly common occurrence but there is also a carbon offset program for another energy-intensive luxury, yachting. Yacht Carbon Offset
specializes in balancing greenhouse gas emissions from yacht charters and private yachts. Projects include renewable energy in Brazil, wind power in China's Shanghai Province and a wind farm in Maharastra, India. They stress that their carbon offset projects offer traceability of individual project actions and for the independent verification and certification of the carbon credits generated. They have an interesting stance on forestry projects. Their website says they do not purchase credits from forestry projects because pure tree-planting schemes seek to create an offset by increasing the amount of stored carbon dioxide. This only matters if the trees will never be cut down, otherwise the CO2 will be released again. They instead focus on alternative energy projects.
Their program calculates carbon offsets based on the types of marine fuel types used for the main engines, gensets, tenders and watertoys and even helicopter fuel if required. The motor yacht Lionheart was recently signed up for carbon offsetting through this program. Certainly the easy answer is to say that people shouldn't be cruising these huge yachts in the first place but I think any reasoned effort to be green has merit.
