Human Impact Unit (Hu) Standards
Version 2024-1, Last Updated September 30, 2024
1. Purpose and Scope
This standard defines the requirements for conducting a Human Impact Unit (Hu) analysis, a metric used to evaluate and compare the societal impacts of sustainability, responsibility, and resilience projects. The Hu methodology enables a standardized, fair comparison between projects of different types by assessing the proportion of a specific problem addressed within a defined community. The standards outlined here provide a framework for defining catchment areas, measuring impact, calculating the size of the problem, and estimating Hu values for comparative purposes.
​
2. Definitions
Human Impact Unit (Hu): A standardized unit measuring the proportion of a specific problem addressed by a project within a community, allowing comparison across different project types.
Catchment: The geographic or demographic area in which a project’s impact is measured.
Units of Impact: The specific metric(s) used to quantify the project’s societal benefit (e.g., pounds of food rescued, acres of habitat restored).
Size of Problem (SOP): The total magnitude of the issue being addressed within the project’s catchment area, quantified in the same units as the project’s impact.
Return on Investment (ROI): The value of Hu per monetary unit spent on the project, enabling financial comparison of societal impact across projects.
​
3. Requirements for Conducting a Hu Analysis
​
3.1 Project Overview
The project must clearly define the scope, objectives, and intended societal impact. This includes:
-
A description of the project’s primary goals (e.g., reducing food insecurity, restoring ecosystems, creating jobs).
-
A clear statement of the community or demographic that the project aims to serve (the catchment area).
-
Specification of the project’s intended units of impact (e.g., pounds of food recovered, acres restored, jobs created).
3.2 Catchment Area Definition
The catchment area must be explicitly defined and justified. This includes:
- The geographic boundary or target demographic for the project.
- The rationale for why this specific catchment area has been selected for analysis.- The affected population will be contained within the catchment area.
3.3 Units of Impact
Each project must define how it measures its impact. The units of impact must:
- Be consistent with the nature of the problem being addressed (e.g., food insecurity should be measured in pounds of food, habitat restoration in acres, job creation in the number of jobs).
- Be clearly defined and applicable to the specific community and problem being addressed.
3.4 Size of Problem (SOP) Estimation
The SOP is critical to determining the scale of the issue within the catchment area. The SOP must be:
- Quantified in the same units as the project’s intended impact.
- Supported by verifiable data or reasonable estimates (e.g., food insecurity data, habitat degradation data, job market statistics).
- Accompanied by a rationale for the estimation method, including any assumptions made (e.g., the average number of meals required per person to eliminate food insecurity).
3.5 Hu Calculation
The Hu value is derived from dividing the project’s annual impact by the SOP within the catchment area. The calculation must:
- Use the following formula for Hu Rate:
Hu Rate = Responsible Community / Size of Problem
- Use the following formula for Hu:
Hu = Impact * Hu Rate
- Be performed annually or over the project’s operational timeframe.
- Be accompanied by a breakdown of each impact component if the project addresses multiple issues (e.g., environmental and social impacts).
- Provide a clear explanation of how the Hu value was derived and what it represents in terms of societal benefit.
3.6 Comparative Analysis of Hu
Hu must enable direct comparison across different project types and scales. The analysis should:
- Use Hu as a common unit to compare the societal impact of various sustainability, responsibility, and resilience efforts.
- Ensure the Hu value is applied equitably, regardless of the nature or location of the project.
- Be adaptable to different scales of problems and projects, ensuring the analysis is fair to both small and large-scale initiatives.
3.7 Estimation of ROI
Projects must include a financial analysis that calculates the ROI based on Hu. This involves:
- Calculating the cost per Hu for each project by dividing the total project cost by the Hu value.
- Comparing ROI between different projects to identify which offers the greatest societal impact per dollar invested.
- Reporting the ROI in a clear and standardized format for ease of decision-making.
​
3.8 Accounting for Uncertainties and Assumptions
Any uncertainties or assumptions made during the Hu analysis must be clearly documented. This includes:
- Describing any assumptions made during the SOP estimation (e.g., average food needs per person, habitat degradation rates).
- Identifying any data limitations or uncertainties in the impact measurement (e.g., incomplete data, modeling assumptions).
- Acknowledging potential nonlinearities or interdependencies between different components of the project that may affect the Hu calculation.
