Puzzling what's green about the so-called "green diesel".

It's green because it comes from recently living biomass. It's not biodiesel, because that definition is specific to the transesterification reaction that produces a methyl ester (biodiesel) and not a hydrocarbon. Green diesel is a hydrocarbon - and whether they specifically say "green diesel" in the press release, green diesel is the term that is used to describe diesel produced by hydrocracking lipids, or diesel produced via BTL (as Choren is doing).

Thanks for clarification.

Green fuel from livestock is an oxymoron. The 2005 UN Report "Livestock's Long Shadow" revealed that world transportation caused about 13% of all co2 equivalent anthropogenic emissions, while livestock accounts for a staggering 18%! And this does not even include the incredible amount of damage done to the environment and people in general. This is pure green-washing, Tyson foods and "green fuel" - how incredibly ridiculous - or at least it would seem that way if ordinary people weren't so brainwashed. It appears that corporations will continue raping the earth and issuing bogus press releases until they cannot afford to support their bloated infrastructure - but what can you expect from such sociopathic, myopic institutions?
