本欧洲标准规定了一种详细的方法，允许生物燃料或生物液体链中的任何经济运营商以标准化和透明的方式计算与其运营相关的实际温室气体排放量，同时考虑到所有重大相关方面。它包括从生物质能生产到最终运输和分配操作的所有环节。该方法严格遵循RED中规定的原则和规则，特别是其附件五、欧盟委员会2010年6月10日关于“计算土地碳储量指南”的决定（针对指令2009\/28\/EC（2010\/335\/EU）[5]附件五）以及欧盟公布的立法文本的任何附加解释佣金。在适当情况下，对这些规则进行澄清、解释和进一步阐述。在计算热耗、电耗和盈余的情况下，还参考了2004\/8\/EC[6]号指令“根据内部能源市场的有效热需求促进热电联产”和相关的欧盟委员会2006年12月21日的决定“为单独的电和热的生产“[7]。本标准的主要目的是规定在生物燃料\/生物液体生产和运输链的每一步估算温室气体排放量的方法。为了建立生物燃料或生物液体的整体温室气体平衡，必须将这些排放量结合起来的具体方式取决于正在使用的监管链系统，并且本身不在EN 16214标准第4部分的范围内。本标准第2部分也按照红色部分的规定详细说明了这些问题。然而，本标准本部分第6条包含了如何整合链条不同部分的一般指示和指南。

This European Standard specifies a detailed methodology that will allow 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 transport 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 well 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 "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 specify 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 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 parts of the chain.
