The Scottish Government Input-Output model has an environmental extension that makes it possible to estimate Greenhouse Gas Emission effects. These were last updated for the High Level Carbon Assessment of the Scottish Draft Budget 2017/18, published on 16th December 2016. The Environmental Input-Output model and methodology underpinning the Carbon Assessment of the Draft Budget remains the same as the Carbon Assessment of the 2016/17 Draft Budget but uses the latest available Greenhouse Gas emissions ratios and HM Treasury deflators. For more information about the methodology used please see the GHG estimation methodology page.
The GHG effects published here detail the estimated direct and indirect greenhouse gas emissions (expressed in tonnes of carbon dioxide equivalent) as a result of £1m final demand from each of the 98 Input-Output industry categories. These are derived from the Scottish Government Environmental Input-Output Model 2010 v3.00. This model is based on the Scottish Government Input-Output tables 2010 (published in August 2014), ONS Input-Output Analytical Tables 2010 (Blue Book 2013 consistent), ONS Environmental Accounts GHG emissions by industrial sector for 2010 (published in July 2016) and HM Treasury deflators (published on 30 November 2016).
Since the Model is applied to 2017/18 Draft Budget spending plans, the GHG effects are in 2017/18 prices.
