Is £13 Billion the actual cost to move from the 80% to 90% decarbonisation target in Scotland? Are we missing something?

The Climate Change Bill, presented by the Scottish Government in May 2018 seeks to raise the ambition of the 2050 target from an 80% reduction in greenhouse gas emissions from the baseline to a 90% reduction. As well as providing the outputs from analysis of the global costs and benefits of climate change action, and the 'administrative costs' for the Scottish Government of moving the target, the accompanying Financial Memorandum presents estimates of the whole system costs for Scotland. We have looked at how these calculations were done, and what is included and excluded from them.
