There are several reasons why existing biofuel

There are several reasons why existing biofuel certification schemes are not joint by many of the economic operators in the biofuels sector. First, the governance structure of these Cy3 NHS ester certifications is often led by large-scale agro industry and the cost structure of certification is cutting out smallholders [3]. Even if some feedstock roundtables are providing incentives for smallholders to meet the high certification costs, most of these schemes still tend to favor big companies able to meet them. These certification schemes should therefore look for a more balanced governance structure incentivizing active participation of smallholders’ representatives [3].
A second factor is the ambiguity created by the multiple uses of some feedstocks (e.g. food, feed, fibre and fuel), while the EU sustainability requirements apply to only the biofuel use [5]. Therefore, an actor can produce a feedstock used for biofuels production in sustainable conditions, while diabetes mellitus may produce the same crop used for other purposes after the conversion of a forest or grassland. In order to avoid land use change, double-standard policies should be avoided and the certification scheme should address feedstock supply chain in spite of the final use [5].
