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，这类因子用于衡量特定流（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，单位为与特定场景相关的可排放物质单位质量的效力或影响当量（例如，排放至大气的每千克氨对应1.88千克二氧化硫当量）。LCIA方法通常与生命周期清单数据结合使用，以估算生命周期评估（life cycle assessment, LCA）中的潜在环境影响。

ReCiPe2016可生成18个中点指标与3个终点指标，且中点与终点指标均分别基于个人主义（Individualist, I）、等级主义（Hierarchist, H）与平均主义（Egalitarian, E）三种文化视角进行构建。

联邦LCA Commons基础流列表（Federal LCA Commons Elementary Flow List, 简称FEDEFL，EPA 2019）是符合美国联邦LCA Commons数据指南的标准化基础流列表。本数据集将ReCiPe2016方法应用于FEDEFL v1.2.3版本的基础流。

本数据集由LCIA格式化工具（LCIA Formatter）v1.1.3（https://github.com/USEPA/LCIAformatter）生成。该工具可将标准化的生命周期影响评价方法的特征化因子，透明地应用于来自权威流列表（如FEDEFL）的基础流。LCIA格式化工具的数据源为原始ReCiPe2016源文件，以及ReCiPe2016到FEDEFL的流映射文件，并通过fedelemflowlist工具（https://github.com/USEPA/fedelemflowlist）调取该映射文件。当FEDEFL中的流场景（例如“大气”）相较于ReCiPe2016的流场景（例如“大气/农村”）不够具体时，LCIA格式化工具将采用ReCiPe2016中相关特征化因子的平均值，应用于该FEDEFL基础流。

本数据集提供的zip压缩包为遵循openLCA规范（https://greendelta.github.io/olca-schema）的JSON文件归档。针对指标类型（中点/终点）与文化视角的每一种组合，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导入FEDEFL v1.2基础流的openLCA v2.1数据库中，并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本身。这种“无流”方法的使用说明可参见https://www.lcacommons.gov/lcia-methods-without-flows。完整的FEDEFL v1.2基础流列表可从联邦LCA Commons基础流列表仓库获取，地址为https://www.lcacommons.gov。

本数据集还附带一份表格格式的方法文件（.parquet格式，https://dmap-data-commons-ord.s3.amazonaws.com/lciafmt/recipe/ReCiPe_2016_v1.1.1_27ba917.parquet）。该.parquet文件遵循LCIA格式化工具的LCIAmethod格式规范（https://github.com/USEPA/LCIAformatter/blob/v1.1.3/format specs/LCIAmethod.md）。parquet文件使用说明：任意Apache Parquet读取工具均可读取该文件。
