Correction to post:
Jcwinnie, Jonas from Biopact here. Thanks for this informative post.
We wrote the article about which biofuels might hit the mark, a bit as a shocker.
The actual directive says nothing about biogas and virtually all other first generation biofuels easily meet the 35% reduction target (see Annex 7 of the directive, here
Our own article was based on a very stringent Swiss study [the Zah study] - the most in-depth of all biofuel lifecycle assessments. This study showed several types of biomass not meeting a 35% reduction. We wrote the piece, to shock some into understanding the consequences of demanding carbon cuts that are higher than any percentage above zero.
In any case, rest assured, biogas will make it.
