Electric Utility Sector Supplement EN16 Total direct and indirect greenhouse gas emissions by weight. 1. Relevance Greenhouse gas emissions are the main cause of climate change and are governed by the United Nations Framework Convention on Climate Change (UNFCC) and the subsequent Kyoto Protocol. As a result, different national and international regulations and incentive systems (such as trading climate certificates) aim to control the volume and reward the reduction of greenhouse gas emissions. This Indicator can be used in combination with EN17 to explain targets for regulations or trading systems at international or national levels. The combination of direct and indirect emissions also provides insights into the potential cost implications of taxation or trading systems for reporting organizations. 2. Compilation 2.1 Different conversion methodologies are available to calculate the amount of greenhouse gas emissions per source. Indicate the standard used, and indicate the methodology associated with the data with reference to the following categories: • Direct measurement (e.g., continuous online analyzers, etc.); Indicator Protocols Set: EN • Transportation of materials, products, and waste; • Venting; and • Fugitive emissions. Emissions from combustion processes and sources will correspond to the direct primary energy from non-renewable and renewable sources as reported in EN3. Note that the direct CO 2 emissions from the combustion of biomass shall not be included but reported separately under GHG Protocol Corporate Standard (revised edition). 2.3 Identify indirect emissions of greenhouse gases resulting from the generation of purchased electricity, heat, or steam (this corresponds with energy consumption reported under EN4). Other indirect emissions (e.g., from organizational travel) are not included since they are accounted for in EN17. 2.4 Report total greenhouse gas emissions as the sum of direct and indirect emissions (as identified in 2.2 and 2.3) in tonnes of CO 2 equivalent. 2.5 Report CO 2 e per MWh, broken down by regulatory regime, for: IP & EUSS EU • Calculation based on site specific data (e.g., for fuel composition analysis, etc.); • Calculation based on default data; and • Estimations. If estimations are used due to a lack of default figures, indicate which basis figures were obtained. Further details on the compilation of this Indicator are available in the WRI /WBCSD GHG Protocol and in the IPCC document as listed under references. 2.2 Identify direct emissions of greenhouse gases from all sources owned or controlled by the reporting organization, including: • Generation of electricity, heat, or steam (as reported in EN3); • Other combustion processes such as flaring; • Physical or chemical processing; • Net generation from all generating capacity; • Net generation from all fossil fuel generation; and • Estimated net delivery to end users. This includes emissions from own generation, as well as purchased power. Explanation: The first bullet refers to the emissions intensity for all generating capacity, and the second bullet refers to that of the fossil generation capacity. A breakdown by regulatory regime is necessary because of the different CO 2 e allocation schemes in place. 3. Definitions Direct emissions Emissions from sources that are owned or controlled by the reporting organization. For example, direct emissions related to combustion would arise from burning fuel for energy within the reporting organization’s operational boundaries. EU Version 3.0/EUSS Final Version 23
IP & EUSS Indicator Protocols Set: EN Indirect emissions Emissions that result from the activities of the reporting organization but are generated at sources owned or controlled by another organization. In the context of this Indicator, indirect emissions refer to greenhouse gas emissions from the generation of electricity, heat, or steam that is imported and consumed by the reporting organization. Carbon dioxide equivalent CO 2 (Carbon Dioxide) equivalent is the measure used to compare the emissions from various greenhouse gases based on their global warming potential (GWP). The CO 2 equivalent for a gas is derived by multiplying the tonnes of the gas by the associated GWP. Regulatory regime Electric Utility Sector Supplement Regulatory regime refers to local, sub-national, national or regional area where there is a common regulatory framework. Net EU Net refers to electricity output to the grid from the power plant. 4. Documentation EU Emissions resulting from direct and indirect energy use can be calculated from the data reported in EN3 and EN4. 5.
