They use various aliases — naysayers, pessimists, The Party of No,
doom-and-gloom’ers, realists, skeptics, and so on. For almost every
aspect of a biobased supply chain or technology, there’s someone
available with 15 reasons why it can’t work.
Why feedstocks will never develop at sufficient yield, or why land
will never be available and affordable; why processing technologies are
doomed to fail, from front end processing to final-step fuel finishing;
why policies are bound to fail, or why finance will never appear. In recent months and years, focus has fallen on financing — or the
lack thereof. But, generally, financing is a creature of risk, or
perceived risk, and the cost of capital is a consequence of how solvable
other risks are thought to be.
10. Indirect Land Use Change — ILUC
Briefly stated, indirect land use change is a theory that the very
success of bioenergy causes land owners in distant lands to change their
planting habits in ways that release sequestered carbon. For example,
rising soybean prices would lead to rising soybean acreage in southern
Brazil, which would drive cattle ranchers to convert forest land to
pasture, causing forest owners to move into the Amazon where they would
release carbon by cutting rainforest.
The danger in the theory is that it has proven impossible to
construct real-world data sets, thus far, to track such a phenomenon —
theorists have been generally relied on global equilibrium modeling that
was not constructed with ILUC in mind. Meanwhile, ILUC has been
enshrined as a penalty factor in biofuels in the EU, for the US
Renewable Fuel Standard, and in California’s Low Carbon Fuel Standard.
Why a scary challenge? ILUC’s proponents have been generally able to
steer the debate such that difficult-to-procure hard data us not
required to enshrine ILUC into policy, but is required to remove it.
“Guilty until proven innocent”, as some might term it.
Open to manipulation? Well, consider this. We reported that in Belgium,
a leaked document circulating among the European Commission shows that
proposed sustainability criteria for biomass would be much weaker than
that for biofuels. The draft would not include ILUC accounting or
accounting for loss of carbon resulting from the use of forests. GHG
targets are set at 60 percent in the draft. The policy is expected for
release this fall.
