[Facility Environmental Module (FEM)](https://support.worldly.io/assessments?hsLang=en#facility-environmental-module-fem) # FEM 4.0: Resources [Click here](https://howtohigg.org/resources-library-fem4-resources/#) to find all supporting documentation, guides and additional downloadable resources, including: - **FEM 2024 How to Higg Guide** - **Higg FEM Reference Guide (PDF)** – This is a reference guide for navigating Higg FEM data. It provides a technical, slightly narrative description of the Higg FEM data as well as reference documentation for all FEM questions (including tooltips, conditionalities, answer options, and points). - **Appendix A. FEM Foundations** – Download Appendix A to understand FEM Foundations and the question set associated. - **FEM4.0 Technical Paper** published by Cascale. - **Guidance FEM 2023 Data Exports** – Download PDF guide on the different csv. files that you can download for individual FEMs or for accessing bulk data. - **REFID Comparison** – Review REFID changes from 2022 to 2023. - **Normal Data Dictionary** – Look up characteristics such as description, inclusion in verification, question-type and applicability, of all FEM2023 questions (identifiable by their REFID). Use this file to guide you in using the Quantitative Impacts CSV and the Raw Response CSVs. - **FEM Performance CSV Data Dictionary** – Look up characteristics such as description and question-type of all calculated fields in the FEM Performance CSV file, identifiable by readable column names. Use this file to guide you in using the Performance CSV. - **FEM Calculations and Methodology**   [Click here](https://howtohigg.org/higg-fem/higg-fem4-scoring-methodology/.) to learn more about Higg FEM scoring methodology, including: - **Higg FEM Scoring System** - The Higg FEM is constantly being updated and improved, which can affect the scoring. Any changes will be posted here and in the appropriate sections. - **Higg FEM Level Advancing Methodology** - Higg FEM questions are structured in three levels (Level 1, Level 2 and Level 3). - **Higg FEM 4.0 Scoring Methodology** - Levels are not equally weighted. Higg FEM weighs Level 2 higher than the other levels because the questions in this level are driving key performance improvement measures such as setting targets and tracking reductions.  - **Applicabilities **- The Higg FEM will include qualifier questions to ensure facilities only answer questions applicable to them.
