So what exactly constitutes a zero emissions circumnavigation of the globe? Below are some rules that my expeditions has to abide by.

- I must start and finish at the exact same location, traveling in one general direction

- The distance traveled has to be a minimum of 40,000km or 21,600NM

- Every line of Longitude must be crossed

- I have to cross the Equator a minimum of two times

- I have to travel through two antipodal points

- Should i have to travel anywhere using motorized transport (for visa collection, medical emergencies) i must return to the exact GPS position

- For the expedition to be completely zero emissions i can only use human and wind power
