ReCiPe2016v1.1 for FEDEFLv1.2 (No flows)

ReCiPe2016 (Huijbregts 2017) is a life cycle impact assessment (LCIA) method. LCIA methods are collections of characterization factors, which are measures of relative potency or potential impact, for a given flow (e.g., NH3 to air) for a set of impact categories (e.g., acidification), provided in units of potency or impact equivalents per unit mass of the flowable associated with a given context (e.g., 1.88 kg SO2 eq/kg NH3 emitted to air). LCIA methods are typically used along with life cycle inventory data to estimate potential impacts in life cycle assessment (LCA). ReCiPe2016 produces 18 midpoint indicators and 3 endpoint indicators, and both midpoint and endpoint are provided using Individualist (I), Hierarchist (H), and Egalitarian (E) cultural perspectives.The FEDEFL or Federal LCA Commons Elementary Flow List (EPA 2019) is the standardized elementary flow list for use with data meeting the US Federal LCA Commons data guidelines.In this dataset, ReCiPe2016 is applied to FEDEFL v1.2.3 flows. This dataset was created by the LCIA Formatter v1.1.3 (https://github.com/USEPA/LCIAformatter). The LCIA Formatter is a tool for providing standardized life cycle impact assessment methods with characterization factors transparently applied to flows from an authoritative flow list, like the FEDEFL. The LCIA Formatter draws from the original ReCiPe2016 source file and the ReCiPe2016 to FEDEFL flow mapping. The LCIA formatter accesses this mapping file through the fedelemflowlist tool (https://github.com/USEPA/fedelemflowlist). Where a flow context is less specific in the FEDEFL (e.g., air) relative to the ReCiPe2016 flow contexts (e.g., air/rural), the LCIA Formatter applies the average of the relevant characterization factors from ReCiPe2016 to the FEDEFL flow.The zip files are a compressed archive of JSON files following the openLCA schema (https://greendelta.github.io/olca-schema). A separate .zip file is provided for each combination of indicator type (midpoint or endpoint) and perspective. Usage Notes for zip file: These files were tested to correctly import into an openLCA v2.1 database already containing flows from the FEDEFL v1.2. They will provide matching characterization factors for any FEDEFL elementary flow already present in the database. These files do not contain the elementary flows. Use of this "No Flows" method is described on https://www.lcacommons.gov/lcia-methods-without-flows. The complete FEDEFL v1.2 flow list may be retrieved from the Federal LCA Commons elementary flow list repository at https://www.lcacommons.gov.An associated .parquet file is available with the method in tabular format (https://dmap-data-commons-ord.s3.amazonaws.com/lciafmt/recipe/ReCiPe_2016_v1.1.1_27ba917.parquet). The .parquet file is in the LCIA Formatter's LCIAmethod format. https://github.com/USEPA/LCIAformatter/blob/v1.1.3/format specs/LCIAmethod.md. Usage notes for parquet file: The .parquet file can be read by any Apache parquet reader.ReferencesHuijbregts, M. A. J., et al. (2017).

ReCiPe2016（Huijbregts等，2017）是一种生命周期影响评价（life cycle impact assessment, LCIA）方法。LCIA方法是特征化因子的集合，特征化因子是针对给定流（例如排放至大气的氨（NH3））在一组影响类别（例如酸化）下的相对效力或潜在影响的度量，单位为与特定情境相关的流质单位质量的效力或影响当量（例如，1.88 kg 二氧化硫（SO2）当量/kg 排放至大气的氨）。LCIA方法通常与生命周期清单数据结合使用，以估算生命周期评价（life cycle assessment, LCA）中的潜在影响。ReCiPe2016可生成18项中点指标与3项终点指标，且中点与终点指标均基于个人主义（Individualist, I）、等级主义（Hierarchist, H）和平等主义（Egalitarian, E）三种文化视角构建。

联邦生命周期评价共同体基础流清单（Federal LCA Commons Elementary Flow List, FEDEFL）（EPA，2019）是符合美国联邦LCA共同体数据指南的标准化基础流清单。本数据集将ReCiPe2016方法应用于FEDEFL v1.2.3的流。本数据集由LCIA格式化工具（LCIA Formatter）v1.1.3（https://github.com/USEPA/LCIAformatter）生成。LCIA格式化工具是一款可提供标准化生命周期影响评价方法的工具，可将特征化因子透明地应用于权威流清单（如FEDEFL）中的流。LCIA格式化工具的数据源为原始ReCiPe2016源文件以及ReCiPe2016到FEDEFL的流映射表。该工具通过fedelemflowlist工具（https://github.com/USEPA/fedelemflowlist）调取该映射文件。当FEDEFL中的流情境（例如“大气”）比ReCiPe2016的流情境（例如“大气/农村”）更宽泛时，LCIA格式化工具将取ReCiPe2016中相关特征化因子的平均值应用于FEDEFL流。

本数据集的zip文件为遵循openLCA架构（https://greendelta.github.io/olca-schema）的JSON文件压缩归档。针对指标类型（中点或终点）与视角的每一种组合，均提供了单独的.zip文件。zip文件使用说明：经测试，本文件可正确导入已包含FEDEFL v1.2流的openLCA v2.1数据库，可为数据库中已有的任意FEDEFL基础流匹配对应的特征化因子。本文件不包含基础流。这种“无流”方法的使用说明详见https://www.lcacommons.gov/lcia-methods-without-flows。完整的FEDEFL v1.2流清单可从联邦LCA共同体基础流清单仓库获取，地址为https://www.lcacommons.gov。
