Voluntary trading of the environmental value of electricity Principle of the system GO = Guarantee of Origin GO market Cancellation
Guarantee of Origin Defined in the Renewable Energy Directive (2009/28/EC): Shall provide proof to a final customer that a given share or quantity of energy was produced from renewable sources as required by Article 3(6) of Directive 2003/54/EC (repealed by Directive 2009/72/EC, The Electricity Market Directive). Standard size of 1 MWh Specific information requirements Energy source and start and end dates of production Whether and to what extent the installation has benefited from investment support Whether and to what extent the unit of energy has benefited in any other way from a national support scheme, and the type of support scheme Etc.
Electricity Disclosure The Electricity Market Directive 2009/72/EC, Artikkel 3(9)) All suppliers of electricity are required to disclose their electricity portfolio with regards to: energy source environmental impacts, specifying the emissions of CO 2 the production of radioactive waste Attributes = The disclosed indicators, representing the environmental information associated with the electricity generation processes.

Objectives of Electricity Disclosure: To provide consumers with relevant information about power generation and to allow for informed consumer choice - not to be based on electricity prices alone http://www.reliable-disclosure.org/electricity-disclosure/ The Electricity Directive introduces the obligation on suppliers to specify the fuel mix and its related environmental impact of the electricity they sell to final consumers. 1. Increase market transparency by providing open and easy access to relevant information, 2. Comply with the consumers right to information regarding purchased products, 3. Enable consumers to make informed choices about suppliers based on the generation characteristics of the electricity they supply, 4. Educate consumers and stimulate electricity generation that contributes to a secure and sustainable electricity system. European Comission, 2004: Note from DG Transport and Energy (http://ec.europa.eu/energy/electricity/legislation/doc/notes_for_implementation_2004/labelling_en.pdf) and Aasen et al., 2012
GOs til bruk i Disclosure For a proper disclosure of the electricity mix, suppliers can use Guarantees of Origin to account for the share of green electricity they sell (http://www.reliable-disclosure.org/electricity-disclosure/). The connection between the Renewable Energy Directive and the Electricity Market Directive entails that the GOs are the carrier of the information of environmental attributes related to the electricity generation (Raadal et al., 2012). Analogous to RECs in the US Ursprungsgarantierna står för miljövärdet av elen, och kan köpas och säljas på en öppen marknad (Energimyndigheten: Faktablad om ursprungsgarantier http://webbshop.cm.se/system/templateview.aspx?p=energimyndigheten&view=default&cat=/fa ktablad&id=3a1e62e4131c48cd9f2125fe79be8e78)

ISO/DIS 14 067 Carbon footprint of products Januar 2012 høringsfrist 6. juni 2012 Kap. 6.3.9.3 Treatment of electricity When a supplier of electricity can deliver a specific electricity product and guarantee that the electricity sale and the associated GHG emissions are not double counted, the data for that electricity shall be used for the product studied. When the supplier of electricity does not provide specific GHG data for the specific electricity product, the GHG emissions associated with the national grid where the life cycle stage occurs shall be used.
ISO/DIS 14 067 Carbon footprint of products Januar 2012 høringsfrist 6. juni 2012 Kap. 6.3.9.3 Treatment of electricity Notes NOTE 1 Regarding double-counting, generator-specific emission factors for electricity used in a process could be used when: a) the process which used the electricity (or used an equivalent amount of electricity of the same type to that generated), and another process did not claim the generator-specific emission factors for that electricity; and b) the generator-specific electricity production does not influence the emission factors of any other process or organization. NOTE 2 In some countries parts of the electricity from renewable energy sources might already be sold/exported as green electricity, and should thus be excluded from the mix to avoid double counting. NOTE 3 Some "green certificates" are sold without coupling to the electricity, which might lead to double counting.
GHG Protocol standards Product life Cycle Accounting and Reporting Standard (oktober 2011, http://www.ghgprotocol.org/files/ghgp/product%20life%20cycle%20accounting%20and%20repo rting%20standard.pdf ): When an electricity supplier can deliver a supplier-specific emission factor and these emissions are excluded from the regional emission factor, the supplier s electricity data should be used. Otherwise, companies should use a regional average emission factor for electricity to avoid double counting.

I det fall ingen information finns om vilket elhandelsbolag som fjärrvärmebolaget har avtal med så används den nordiska residualmixen som grund för miljövärdering.
Skepsis til systemet i Norge Har GOs/Disclosure effekt på fornybar produksjon? Currently Electricity Disclosure has very low, or no, impact on the total production of electricity from renewable sources (Gillenwater, 2008, Raadal et al., 2012) For tidlig å evaluere systemet (10 års perspektiv med lave priser) Men: Hva er potensialet til systemet - finnes forskning som viser at systemet ikke har potensial til å bidra til økt produksjon?
Interaksjoner med TGC (El-cert) Obligatorisk system påvirker produksjonsmiks Quota System/TGC: Affect the production mix in a country over time (increased renewables) Electricity generation Customers Green customers voluntarily purchasing GOs Ordinary customers, purchasing electricity without any specific requirements Electricity Disclosure: Provide information about the customer s consumption mix Frivillig system påvirker forbruksmiks Disclosure related to the purchased GOs Disclosure related to the Production Electricity Mix, corrected by physical import/export and amount of relevant tracking systems (e.g. GO) = Residual Mix In the long-term, Electricity Disclosure together with a TGC system may implicit impact the total production of electricity from renewable sources when compared to a stand-alone TGC system, by leading to increased TGC targets (Raadal et al., 2012).
Muligheter for å påvirke fornybar produksjon? Akseptert generelt og i klimaregnskap/dokumentasjon Økt etterspørsel fra forbrukere? Økte priser? Økt produksjon? Gi mekanismene en mulighet til å virke?
Tidsperspektiv og felles virkemiddelbruk Viktig med et langsiktig tidsperspektiv GOs/Disclosure = én brikke i en stor virkemiddelpakke The increased use of electricity produced from renewable energy sources constitutes an important part of the package of measures needed to comply with the Kyoto Protocol (Renewable Energy Directive, 2009/28/EC) There are a number of good arguments for using a mix of instruments to address a specific environmental problem (OECD, 2007)
Kort oppsummering GOs/Electricity Disclosure allocates the environmental value of renewable electricity generation to the customers who are willing to pay for it creates a mechanism for a customer driven demand for renewable electricity Can supplement other measures (e.g. TGC) Fits well into the logic of a liberalised market where communication between suppliers and customers becomes a key element (Markard and Truffer, 2006)
