Don't throw out California's ILUC factors yet

Soy biodiesel is generally understood to have high indirect land use change (ILUC) emissions.  For example, California assigns an ILUC factor of 29 gCO2e/MJ to biodiesel in its Low Carbon Fuel...Newer is not always better. California’s ILUC analysis relies on stronger evidence on palm oil expansion than a new study from Argonne National Laboratory.
