本欧洲标准规定了一种详细的方法，允许生物燃料或生物流动链条中的任何经济运营商以标准化和透明的方式计算与其业务相关的实际温室气体排放量，并考虑所有重大相关方面。它包括从生物质生产到终端运输和分销业务的链条的所有步骤。 该方法严格遵循“RED”规定的原则和规则，特别是其附件五，2010年6月10日的EC“2009年/ 28/EC指令”附件五（2010/335/EU）[5]以及欧盟委员会公布的立法文本的任何其他解释。在适当的情况下，这些规则得到澄清，解释和进一步阐述。在会计热电消费和盈余的背景下，还参考了2004/8/EC号指令[6]，“关于在内部能源市场中有用的热量需求促进热电联产”以及相关的欧盟委员会决定2006年12月21日“建立分散生产电力和热量的协调效率参考值”[7]。 本标准的主要目的是指定一种估算方法

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.
