|Land Availability||Technical developments are assumed to give rise to yield increases, as well as the take-up of SGB technologies.||
This modelling is not incorporated into the core scenarios evaluated in the present study. Thus, while technical developments are considered within the book-length discussion, they have no bearing on the core scenarios.|
Modelling also envisages rapid increases in land take for bioenergy beyond 2030.
|Land use change||Very limited discussion of the impact of land use change, either at a domestic or international level.|
|Socio-Eonomic factors||Attempts are made to model environmentally-sensitive scenarios where the bioenergy uptake is limited by public concerns and objections.||This modelling is not extended to the core scenarios. Consequently, these projections are free of the limitations that may be imposed.|
|No discussion is given on the uncertainty surrounding supplier uptake.|
|Conversion Technologies||Technical developments in conversion processes are taken into account within the book-length discussion.||Developments in accelerated technologies are not incorporated into the core scenarios.|
|Bioenergy Imports||Sustainability concerns are assumed to give rise principally to the domestic production of biofuels.||There is a lack of consideration of the implications of modest imports.|
