What is Higg FEM?
Higg Facility Environmental Module (Higg FEM) is a facility-level environmental assessment tool developed and maintained by Cascale for apparel, textile, footwear and other manufacturing facilities. Facilities complete and share their assessments on Worldly.
Facilities first complete Site Info & Permits and then assess annual performance across seven environmental areas: environmental management systems, energy and greenhouse gases, water, wastewater, air emissions, waste and chemicals management. FEM includes quantitative consumption and emissions data as well as qualitative information about management systems, targets, procedures and implementation.
Higg FEM verification (vFEM) involves a Cascale-approved verifier checking the accuracy of a facility's self-assessment and supporting evidence. It is not ESG certification or a pass/fail decision, and there is no universal minimum passing score for all facilities.
Under Higg FEM Verification Protocol v1.6, checked on 27 August 2026, FEM2025 verification covers applicable Level 1 questions across all FEM areas. Level 2 and 3 responses can remain self-assessed, so an overall result may be shown as a Partially Verified Score.
The official FEM verification methods include onsite and offsite verification. The method used must be checked against the customer's intended use, the current protocol and the service provider's actual scope. Public disclosure of Higg Index scores requires onsite verification and compliance with the current Higg Index Communication Guidelines.

ELIGIBILITY
Eligibility and preparation
- 01Facilities that want to measure annual environmental performance systematically and identify improvement priorities
- 02Facilities asked by customers, brands or supply chain partners to provide a FEM self-assessment or verified results
- 03Facilities seeking independent checks of environmental data before sharing results with partners
- 04Facilities with a Worldly account and a valid subscription that provides access to Higg FEM
- 05Facilities able to answer all applicable self-assessment questions in English, reach 100% completion and post the assessment on Worldly
- 06Facilities able to define the legal and physical scope covered by one FEM using registration and operating-permit information
- 07Cascale does not require every facility to undergo FEM verification. Facilities should determine whether verification is needed, the deadline and the required method by considering customer requirements and the intended use of results.
BENEFITS
Potential benefits
- 01Improve the accuracy and reliability of self-assessment responses and environmental data
- 02Identify environmental performance and improvement needs using overall and area-level results
- 03Share more reliable FEM data with supply chain partners
- 04Improve consistency and comparability across facilities using the same FEM framework
- 05Track changes in environmental performance over reporting years
- 06Build an evidence base for environmental reporting and supply chain data requests
PROCESS
Assessment and verification process
- 01
[Facility] Confirm requirements and reporting year
Confirm the FEM reporting year, submission deadline, need for verification and intended use required by the customer or brand.
- 02
[Facility] Prepare a Worldly account and subscription
Check the Worldly account and arrange a service plan that provides access to FEM for the reporting year. FEM is subscription-based; check available assessment years on Worldly.
- 03
[Facility] Complete the FEM self-assessment
Complete Site Info & Permits first, then answer the applicable questions across the seven environmental areas. Complete the assessment in English and prepare evidence supporting numerical data and management-system information.
- 04
[Facility] Complete and post the self-assessment
Answer all applicable questions, reach 100% completion and post the assessment on Worldly. The self-assessment must be posted before verification can begin.
- 05
[Facility / RST] Confirm scope, method, schedule and fees
Contact RST about availability and service conditions. Confirm the scope, method, anticipated person-days, evidence and schedule. Worldly subscription fees, the Cascale Verification Access Fee and verification-service fees are separate cost components; check the quotation and payment terms.
- 06
[Facility] Select the verifying body on Worldly
Confirm the contract and verification conditions and check the contracted verifying body's official registered name. Then choose that organization using Select Verifying Body on Worldly.
- 07
[Verifying body] Assign verifiers and communicate the plan
Higg FEM Verification Protocol v1.6 requires verifier assignment and communication of the verification plan at least 10 working days before verification starts. Applicable conflict-of-interest requirements must be checked, including restrictions on assigning personnel who trained or consulted for the same facility.
- 08
[Facility / RST] Conduct verification
Onsite verification includes an opening meeting, document and data review, staff interviews, facility and equipment checks, evidence collection and a closing meeting. Offsite verification uses documents, photographs, digital records, video meetings and remote interviews. Verifiers check responses and record corrections and comments where needed.
- 09
[Verifying body] Enter results and complete internal quality review
Higg FEM Verification Protocol v1.6 requires results, corrected responses and verifier comments to be entered in vFEM. Before submission for facility review, an independent Report Reviewer who did not take part in the verification must complete internal quality review. The verifying body must enter results on Worldly and reach VRC within 14 business days after verification activities are completed.
- 10
[Facility / RST] Review results and address edits or disputes
Review the VRC results. Use Request Edit / VRE for factual or data-entry errors, or the formal dispute process where appropriate. If there are no issues, finalize the results. The verifier decides whether changes are justified by evidence and the protocol; results are not changed solely by negotiation between the facility and verifier.
- 11
[Facility] Finalize, post and share results
Finalize the reviewed results and post them on Worldly. FEM2025 vFEM includes Level 1 verification results. If unverified Level 2 and 3 responses contribute to the overall score, it may be shown as a Partially Verified Score. Distinguish self-assessed information from the actual verified scope when sharing results.
RST EXPERTISE
What to confirm with RST
When contacting RST, provide the facility location and production processes, reporting year, customer requirements, preferred schedule and evidence readiness. Confirm the verifying body’s current approval, available methods and service scope, schedule and fees before contracting. Verification does not guarantee a particular score, brand approval or a commercial outcome.
