SQCB reduces the need for user entries to the most relevant and best-known parameters of the biofuel pro-duction chain. Based on this questionnaire, a specific inventory is automatically modelled and linked with background data to a full life cycle inventory. SQCB calculates the environmental impact assessment and checks the results against sustainability criteria.
The simplified modelling approach limits the applicability of the SQCB to value chains similar to the reference chain in the tool. For example, complex biorefineries with multiple co-products and feedstocks cannot be modelled in this framework. Furthermore, in-depth know-how on land transformation, cultivation and fuel processing of the specific biofuel chain is needed for an accurate environmental impact assessment. SQCB is therefore only to be seen as a rapid screening that gives a first estimation on the overall sustainability and potentially critical factors of a biofuel production chain. SQCB can not cover a complete reproduction of the far more complex reality.
The user of SQCB hereby agrees of having notified that the use or outcome of SQCB system and data base does in any case neither stipulate a legal basis for an application at the responsible Federal Office nor do positive outcomes or results guarantee a positive judgement for an application.
SECO as owner and data holder of the SQCB data base as well as Empa, Agroscope Reckenholz-Tänikon ART and HTW Berlin as designers of the SQCB exclude any kind of responsibility for the accuracy and cor-rectness of background data as well as the generation of knowledge, results or benchmarking due to SQCB calculation, the use and commercialization thereof or any kind of damage directly or indirectly derived from the use of SQCB.
