To provide context to the future trajectories that are the Calculator's focus, historical time series data has been incorporated into the Excel version of the Calculator (see the intermediate output worksheet).
Adding this information was also useful for:
- mapping the source data behind the model (an explanation is provided in a column to the right of the data)
- making an assessment of whether the model should be rebased with a more recent base year
A selection of charts showing the historical data against the future trajectories as put forward in DECC's four Carbon Plan example pathways are available in the following file: historical_data_charts
