Our approach to modelling decarbonisation (including generating emissions projections and estimating the impact of emissions reducing interventions) is a top-down method that is sensible for regional economies. By top-down we mean that the average performance, in terms of annual emissions generating activity, of a single unit of development (dwelling, job etc) is representative, with variations within any given sector or sub-sector category being insignificant at a large enough scale.
Core to our assumptions is that a community will grow or change irrespective of any decarbonisation intervention or policy decisions in the scope of the analysis.
This section explains our method for estimating future emissions, how interventions are encoded within this framework and the specific assumptions made for each intervention area.
