I've not seen the published data on the emissions but heard in an interview that it's "nearly as clean as hydrogen while being much more economical."

Here's another one.

BILLINGS, Mont. (AP) - A new study says jet fuel made with the oilseed
crop camelina could cut greenhouse gas emissions by up to 84 percent
compared with jet fuel from petroleum.
The finding is expected to be used by the aviation industry as it weighs a
number of alternative fuels with the potential to reduce costs and curb
emissions.
Camelina is considered well-suited to Montana and other arid Northern
Plains states because it needs little water. Terrance Scott with the
aircraft manufacturer Boeing says camelina is one of a handful of crops
with the potential to provide sufficient "feedstock" to make large
quantities of jet fuel.
However, the industry has struggled to attract growers willing to switch
to the crop. Also, falling oil prices have dampened its economic appeal.
The greenhouse gas emissions study was done by the Sustainable Futures
Institute at Michigan Technological University. It was funded by the
camelina industry and conducted with jet fuel from camelina seeds
developed by a Bozeman company, Sustainable Oils.
For the study, lead author David Shonnard said he conducted a "life cycle"
comparison of camelina with petroleum, meaning he factored in the
greenhouse gas emissions from fertilizing, growing, harvesting and using
the crop.
Conventional camelina, Shonnard said, can cut greenhouse gas emissions by
60 to 70 percent with no loss of performance for the fuel.
The 84 percent reduction in greenhouse gases was based on a strain of
camelina expected to need less fertilizer and yield more pounds per acre
than types of the crop currently in production.
"These next generation biofuels are true hydrocarbons and on a molecular
level indistinguishable from fossil fuels," said Shonnard, a chemical
engineering professor at Michigan Tech.
Sustainable Oils General Manager Scott Johnson said Shonnard's study could
help sell dubious farmers on camelina by showing them its market
advantages.
"It's been a little slow start for camelina," Johnson said. "They don't
want to grow something that doesn't have a fit."
Shonnard said he expected that within a few years a market will develop
for camelina and other biofuels such as jatropha, switchgrass and algae.
With the worldwide population growing -- and worries over global warming
intensifying -- he said the "trends are in place" for the biofuels market
to expand as at least a partial replacement for petroleum.
