In the Energy White Paper of 2003 the UK Government set itself the goal of working towards reducing carbon emissions by 60% by 2050. This report explores the scope for achieving such reductions within the housing
stock through energy efficiency measures and the uptake of low carbon technologies, such as renewable
energy. It examines the current potential for such improvements, including assessments of their
cost-effectiveness. It also assesses the effects that past energy efficiency policies (such as grants, energy
labelling and Building Regulations) have had. Extensive tabulations of hard-to-find data on cost-abatement
analyses and past energy efficiency policies are included. Finally, using a detailed bottom-up modelling
approach, it considers what could happen in the future, exploring a series of five scenarios that progressively
introduce increasing levels of energy efficiency improvements and low carbon technologies. It shows that,
although very challenging, a 60% reduction by 2050 is feasible and might actually be achieved cost-effectively. 80 pages.
