the craft completed the round-the-world trip using 100 per cent renewable biodiesel fuel, with a net zero carbon footprint

So, riddle me this Batman.... How can you drive a carbon-fuel-based vehicle around the world, and wind up with zero emissions?

"Net Zero" to me, sounds like fudged accounting.

The theory is that the carbon-based fuel acquired its carbon from the atmosphere recently during creation of said fuel, was burned, and returned the same carbon back to the atmosphere. Free CO2 is absorbed into a plant, plant is converted to biodiesel, biodiesel is burned, emissions consists of same carbon atoms absorbed not long before. Net atmospheric carbon change: zero.

By paying Pope Al Goreacle 1 $10K in "Carbon Indulgences" to forgive them of their carbon sins.
