Corporate greenhouse gas inventories, guarantees of origin and combined heat and power production - Analysis of impacts on total carbon dioxide emissions

Using a consequential CO2 assessment method for comparison, the study shows that purchasing decisions supported by the Corporate Standard or the GO scheme can increase total CO2 emissions. It also shows that the Corporate Standard and EU frameworks can counteract CHP production and its contribution to CO2 emissions reduction. We recommend that consequential GHG assessment methods be used for emissions reduction decisions, including when designing policy instruments aimed at emissions reduction.
