- Environmental Management System
- Energy / Greenhouse Gas Emissions
- Air Emissions
- Chemicals Management
Each Impact Area is Comprised of Three Levels
Questions are built in a three-level structure (Levels 1, 2 and 3) which signifies general thresholds of good, better, best environmental practices:
- Level 1 - Awareness and understanding of sources and systems
- Level 2 - Setting targets and tracking progress
- Level 3 - Leading practices
Sections are Weighted Equally
All sections are worth an equal portion (14.3%) of the total points assigned to the FEM Higg Index score. This is because there is no scientific consensus around how to compare the value of water consumption vs. say energy use.
Levels are Weighted Differently
Unlike sections, levels are not weighted equally. Higg weights Level 2 higher than the other levels because this is the level where actions, targets, and reductions are measured. The purpose of Higg is to drive action and impact. Therefore, we have weighted Level 2 with the most points to incentivize the behavior of taking action by setting targets and making actual reductions. Also, most factories are scoring at Level 1, so we would like to focus points on Level 2 to encourage advancements.
- Level 1 is worth 25% of the total possible points. (Unless the applicability questions stop you at Level 1, then Level 1 is worth 100% of total possible points.)
- Level 2 is worth 50% of the total possible points.
- Level 3 is worth 25% of the total possible points.
Calculating points for each question
The number of points possible varies from question-to-question depending on how many questions are in the level. For example, if water use has five questions in Level 1, then each question will be worth 20% of the possible points for Level 1. If air emissions has one question in Level 1, then that question will be worth 100% of the possible points for Level 1.
You earn points based on your answer to each question:
- For each “yes” answer, you receive full points.
- For each “partial yes” answer you receive half points.
- For each “no or unknown” answer, you receive zero points.
At the end of the module, your total points out of points possible are calculated and your resulting Higg Index score is the percentage of points possible that you achieved.
The new Higg FEM will include qualifier questions to ensure that you only answer questions applicable to your factory type. These questions are called “applicability tests”. You will be asked applicability questions at the start of four sections of the Higg FEM:
- Water Use: are you a heavy or light user?
- Air Emissions: do you have sources of outdoor or indoor air emissions?
- Wastewater treatment: What type of wastewater do you produce and how do you treat it?
- Chemicals: do you use chemicals in production processes or not?
Water Use Applicability
- If you are a heavy user of water, you will answer all questions. If you are a light user of water, you only answer questions in Level 1. No matter which applicability category you fit into, your total water score will be 14.3% of your total FEM score.
Air Emissions Applicability
- If you do not have any sources of emissions to air, you skip this entire section. Air will then be 0% of your total points and all other section weights will adjust accordingly.
- Similar to chemicals management, you will not be able to skip the wastewater section. Instead, you will be asked different questions depending on how you treat your wastewater.
- If you use chemicals in production, you will be asked all questions in all three levels. If you do not use chemicals in production, you will be asked a subset of questions in all three levels. Your questions will differ, but the scoring approach does not change. This is because chemicals management must happen at all facilities, there is no use case where it’s possible to opt out of chemicals management.
Scores will be presented as percentages of points possible. This is because the applicability tests mean that facilities will not all answer the same number of questions. By showing points in terms of percentage, we enable more comparability between results.
