The real cost

Of course an 'eco holiday' that involves flying to the other side of the world is a contradiction in terms. Your flight will emit vast quantities of carbon dioxide, contributing to global warming. One answer is to offset the emissions by paying money to a company which will invest it in energy saving and green technology projects around the world. Purists see this as a cop-out, like dropping litter on a pristine beach then buying a big litter bin to compensate, but the unarguable fact is that it's better than nothing. Go to www.climatecare.org to calculate your emissions, and offset them.
