Details

Valuing energy use and greenhouse gases is vital to ensure government takes full account of climate change and energy impacts when appraising and evaluating public policies and projects.

This guidance provides government analysts with a set of rules for valuing energy usage and greenhouse gas emissions, and is drafted in consultation with analysts across government.

It contains practical information about:

  • the implementation of the carbon valuation methodology for UK policy appraisal
  • the reporting requirements for compliance with carbon budgets
  • how to calculate the cost effectiveness of climate change policies (see chapter 5 of ‘Valuation of energy use’ for full details on cost effectiveness)

The guidance supplements the HM Treasury: Green Book, which is general guidance on how to conduct appraisal and evaluation.
