Valuing changes in greenhouse gases, including carbon, is vital to ensure climate change impacts are taken into account when appraising and evaluating public policies and projects. Carbon values used during policy appraisal are published as part of the Green Book supplementary guidance: valuation of energy use and greenhouse gas emissions for appraisal. A summary of the current carbon values for 2030, 2040, 2050 is given in the table below (the full annual series can be found in table 3 of the attached). The Government is not intending to publish equivalent figures for each of the OECD countries.
