The Green Book has supplementary guidance on the valuation of energy use and greenhouse gas emissions. This is found here: https://assets.publishing.service.gov.uk/media/65aadd020ff90c000f955f17/valuation-of-energy-use-and-greenhouse-gas-emissions-for-appraisal.pdf
That supplementary guidance notes that appraisals should consider the greenhouse gas emissions content of all of the materials that are used to implement a proposal. This applies both to materials produced in the UK, as well as those imported from abroad.
