This Working Paper considers the development of a new UK MARKAL & MARKAL-Macro (M-M) energy systems model. The focus of this report is on the extensive range of UK 60 per cent CO2 abatement scenarios and sensitivity analysis run for analytical insights to underpin the 2007 Energy White Paper.

This analysis was commissioned by the DTI to underpin the development of the 2007 UK Energy White Paper, and this technical report is a companion publication to the policy focused discussion of the modelling work (DTI, 2007).
