 In 2013, CDP introduced new recommendations for accounting and reporting of Scope 2 emissions, preceding the final GHG Protocol Scope 2 Guidance  New recommendations allow for the use of a market-based method of accounting for Scope 2 emissions  Factors that favour the use of the new approach:  Unresolved double counting and quality issues in company reporting  Existence of effective systems to avoid double counting of properties sold separately from physical electricity  Potential role of consumer choice in changing markets by shifting demand Market-based method for Scope 2 accounting

 CDP recommends that responding companies follow a hierarchy of guidelines when selecting emissions factors for Scope 2 accounting, and use:  1. Source specific emissions factors, based on renewable energy tracking systems  2. Supplier specific emission factors, particularly when this is established country practice, and robust methodologies and regulation require supplier disclosure  3. If 1 and 2 are not possible, companies should use, in order of preference:  Corrected grid average factors (residual mix); or  Grid emission factors that reflect import and export of electricity; or  Production based grid emission factors Scope 2 accounting recommendations

 CDP asks companies to:  Clarify whether they plan to achieve their Scope 2 targets through reduction of energy consumption or through the purchase of low carbon energy  Report one Scope 2 figure, with emission factors determined following the hierarchy of guidelines and breakdown by country or region (tCO 2 )  Disclose purchased and consumed electricity used for Scope 2 calculation (activity data), by country or region (MWh); this is optional in the GHG Protocol Guidance  Disclose the amount of purchased and consumed electricity accounted as green power, by country or region (MWh)  Disclose information related with electricity accounted for at zero emissions factor Scope 2 reporting in CDP questionnaire

Scope 2 reporting in CDP questionnaire

 Reporting system is designed to maximise transparency while minimising complexity  Quality of reporting would increase if information was provided for each sub region of the grid, as opposed to countries or regions; our assessment is that this is still too advanced to demand of reporting companies  CDP and GHG Protocol team have worked together for many years in order to reach maximum alignment between the two initiatives, and this effort will continue after the publication of the final version of the Scope 2 Guidance  We expect full compatibility between CDP guidelines and GHG Protocol Guidance, with only minor changes required to accommodate dual Scope 2 reporting Future evolution of CDP’s guidelines
