BS EN 16214-4:2013EN 16214-4:2013 (E) 4 Introduction Directive 2009/28/EC 1 of the European Commission on the promotion of the use

19、 of energy from renewable sources, referred to as the Renewable Energy Directive (RED), incorporates an advanced binding sustainability scheme for biofuels and bioliquids for the European market. The RED contains binding sustainability criteria to greenhouse gas savings, land with high biodiversity

20、value, land with high carbon stock and agro-environmental practices. Several articles in the RED present requirements to European Member States and to economic operators in Europe. Non-EU countries may have different requirements and criteria on, for instance, the GHG emission reduction set-off. The

21、 sustainability criteria for biofuels are also mandated in Directive 98/70/EC 2 relating to the quality of petrol and diesel fuels, via the amending Directive 2009/30/EC 3 (as regards the specification of petrol, diesel and gasoil and introducing a mechanism to monitor and reduce greenhouse gas emis

22、sions). Directive 98/70/EC is referred to as the Fuels Quality Directive (FQD). In May 2009, the European Commission requested CEN to initiate work on standards on: the implementation, by economic operators, of the mass balance method of custody chain management; the provision, by economic operators

23、, of evidence that the production of raw material has not interfered with nature protection purposes, that the harvesting of raw material is necessary to preserve grasslands grassland status, and that the cultivation and harvesting of raw material does not involve drainage of previously undrained so

24、il; the auditing, by Member States and by voluntary schemes of information submitted by economic operators; Both the EC and CEN agreed that these may play a role in the implementation of the EU biofuel and bioliquid sustainability scheme. In the Communication from the Commission on the practical imp

25、lementation of the EU biofuels and bioliquids sustainability scheme and on counting rules for biofuels (2010/C 160/02, 4), awareness of the CEN work is indicated. It is widely accepted that sustainability at large encompasses environmental, social and economic aspects. The European Directives make m

26、andatory the compliance of several sustainability criteria for biofuels and bioliquids. This European Standard has been developed with the aim to assist EU Member States and economic operators with the implementation of EU biofuel and bioliquids sustainability requirements mandated by the European D

27、irectives. This European Standard is limited to certain aspects relevant for a sustainability assessment of biomass produced for energy applications. Therefore compliance with this standard or parts thereof alone does not substantiate claims of the biomass being produced sustainably. Where applicabl

28、e, the parts of this standard contain at the end an annex that informs the user of the link between the requirements in the European Directive and the requirements in the CEN Standard. BS EN 16214-4:2013EN 16214-4:2013 (E) 5 1 Scope This European Standard specifies a detailed methodology that will a

29、llow any economic operator in a biofuel or bioliquid chain to calculate the actual GHG emissions associated with its operations in a standardised and transparent manner, taking all materially relevant aspects into account. It includes all steps of the chain from biomass production to the end transpo

30、rt and distribution operations. The methodology strictly follows the principles and rules stipulated in the RED and particularly its Annex V, the EC decision dated 10 June 2010 “Guideline for calculation of land carbon stocks“ for the purpose of Annex V to Directive 2009/28/EC (2010/335/EU) 5 as wel

31、l as any additional interpretation of the legislative text published by the EU Commission. Where appropriate these rules are clarified, explained and further elaborated. In the context of accounting for heat and electricity consumption and surpluses reference is also made to Directive 2004/8/EC 6 on

32、 “the promotion of cogeneration based on a useful heat demand in the internal energy market” and the associated EU Commission decision of 21/12/2006 “establishing harmonised efficiency reference values for separate production of electricity and heat” 7. The main purpose of this standard is to specif

33、y a methodology to estimate GHG emissions at each step of the biofuel/bioliquid production and transport chain. The specific way in which these emissions have to be combined to establish the overall GHG balance of a biofuel or bioliquid depends on the chain of custody system in use and is not per se

34、 within the scope of this part 4 of the EN 16214 standard. Part 2 of the standard, addresses these issues in detail also in accordance with the stipulations of the RED. Nevertheless, Clause 6 of this part of the standard includes general indications and guidelines on how to integrate the different p

35、arts of the chain. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (

36、including any amendments) applies.

37、 and verifiers for biofuels and bioliquids Part 2: Conformity assessment including chain of custody and mass balance 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 16214-1:2012 apply. 4 Common elements 4.1 General A number of elements are relevant to

38、 several steps of the biofuel/bioliquid production and transport chain. They are described in this clause to which reference is made in subsequent clauses as appropriate. BS EN 16214-4:2013EN 16214-4:2013 (E) 6 4.2 Greenhouse gases and CO2equivalence The general definition of a greenhouse gas is giv

39、en in Part 1 of this standard. Total GHG emissions are expressed in CO2equivalent (CO2eq) calculated as: Mass(CO2eq) = mass(CO2) + GWPCH4x mass(CH4) + GWPN2Ox mass(N2O) (1) where GWPCH4and GWPN2Oare the Global Warming Potentials of CH4and N2O respectively, as defined in the RED. Current values to be

40、 used are given in Annex A. 4.3 Data quality and sources Estimating the GHG emissions associated with an activity requires numerical data, often from a variety of sources. This typically involves data generated by an economic operator (such as quantities of material or energy used or produced) and d

41、ata acquired from external sources (such as the GHG balance of material or energy used or produced). Data generated by the economic operator shall be supported by appropriate records so that they can be audited and verified. Data associated with imported material and energy streams will often be obt

42、ained from the supplier. Care shall be taken that such data is fit for purpose, well documented and transparent. Literature data shall be fit-for-purpose and obtained from well documented, transparent and publicly available sources. In particular it should be as recent as possible and, where relevan

43、t, be applicable to the geographical area where the activity takes place. Generally, data is used for calculations covering a certain period of time as stipulated by the chain of custody scheme (see Clause 6). This may correspond to the production of a product consignment or, for continuous operatio

44、ns, to a given period of time. For data such as physical properties (e.g. heating value, carbon content etc.) the value used shall be close to the weighted average during the period i.e. the variability of such data within the time period shall be taken into account. 4.4 Units and symbols This stand

45、ard does not specify the units to be used by economic operators to perform calculations and express results. Different trades associated with different steps of biofuel/bioliquid production and transport chain commonly use specific units which are widely accepted and understood within that community

46、 and such units may be used. The only mandated unit is for the overall GHG balance of the biofuel/bioliquid that shall be expressed in g CO2eq/ MJ of the biofuel/bioliquid. However, units used within a calculation algorithm shall in all cases be clearly stated and be mutually consistent. Table 1 giv

47、es the recommended units and symbols.
