ESG isn't just for public companies anymore. Contractors and field-service businesses are being asked to report safety metrics through ISNetworld, Avetta, and client questionnaires. Here's what those metrics mean, how they're calculated, and how your EHS program connects to your ESG score.
ESG — Environmental, Social, and Governance — started as a framework for evaluating publicly traded companies. It has since migrated into supply chain management, and contractors who work for Fortune 500 companies, large general contractors, or operating companies in oil and gas, utilities, or petrochemicals are increasingly being asked to produce ESG data as a condition of doing business. The questionnaires arrive through platforms like ISNetworld, Avetta, and Veriforce, and the answers determine whether a contractor is approved to work on a given job.
Most contractors don't think of their safety program as an ESG program. But the "S" in ESG — the Social pillar — is almost entirely built from EHS metrics. If your safety records are in order, you're most of the way to meeting what your GC clients are asking for.
The three pillars break down differently for field operations than they do for a corporate sustainability report:
Environmental encompasses energy use, fuel consumption, waste generation, spills, and emissions from operations. For most contractors, this means tracking fuel used by equipment fleets, disposing of waste in compliance with applicable regulations, and documenting any environmental incidents — spills, releases, or permit violations. Greenhouse gas (GHG) accounting is increasingly relevant even for smaller operations: Scope 1 emissions (direct from owned equipment), Scope 2 (purchased electricity for offices or facilities), and Scope 3 (supply chain and indirect emissions) form the framework that large clients use to assess their contractor ecosystem's total carbon footprint.
Social is where EHS and ESG fully overlap. Worker safety is the primary social metric for contractors. The data points that matter: TRIR, DART rate, EMR/XMOD, training completion rates, the quality of incident investigation, and the presence of a functioning safety management system. Secondary social metrics include labor practices (wage compliance, anti-discrimination, benefits), community impact, and supply chain labor standards.
Governance covers how an organization manages itself — recordkeeping accuracy, audit readiness, compliance with applicable regulations, anti-corruption policies, and management accountability. For contractors, this translates to: Is your OSHA 300 log accurate and current? Do you have written safety programs for applicable standards? Is your prequalification data up to date? Can you produce documentation on request?
Large owner-operators and general contractors are under ESG reporting obligations from investors, lenders, and regulators. When they report their Scope 3 emissions or their supply chain safety performance, they are aggregating data from their contractor base. A contractor with poor TRIR numbers or outdated prequalification data introduces liability — both regulatory and reputational — into that supply chain.
Contractor prequalification platforms are the mechanism for collecting this data at scale. ISNetworld, Avetta, and Veriforce function as third-party auditors: contractors self-report their safety metrics, insurance certificates, written programs, and regulatory compliance history. The platform verifies and scores the submissions. Owner-operators query the platform rather than managing contractor prequalification in-house. A contractor who fails to maintain their profile or whose safety metrics fall below client thresholds gets removed from the approved contractor list — which means they can't bid the work.
This system means that EHS compliance is no longer just about avoiding OSHA fines. It directly affects which jobs a contractor can pursue and which clients they can serve.
TRIR — Total Recordable Incident Rate. This is the primary safety metric in every contractor prequalification system. The formula: (Number of OSHA recordable incidents × 200,000) ÷ Total hours worked. The 200,000 figure represents 100 employees working 2,000 hours per year — it normalizes the rate so you can compare across companies of different sizes. A TRIR of 2.0 means 2 recordable incidents per 100 employees per year. Industry averages vary significantly — construction runs around 2.5, oil and gas around 1.0. Many clients require a TRIR below a defined threshold (often 1.0 or lower) to qualify for work.
DART Rate — Days Away, Restricted, or Transferred. DART measures the severity of incidents, not just their frequency. The formula is the same structure: (DART cases × 200,000) ÷ Total hours worked. A DART case is any recordable incident that results in days away from work, restricted duty, or job transfer. A company can have a moderate TRIR but a low DART rate, which signals that injuries are occurring but are minor. A high DART rate relative to TRIR indicates more serious injuries.
EMR / Experience Modification Rate. Also called XMOD, this is the insurance industry's safety metric — not OSHA's. Your EMR compares your actual workers' compensation losses over the prior three policy years to the expected losses for a company of your size and industry. An EMR of 1.0 is average. Below 1.0 means your losses are better than average and you pay a discount on workers' comp premiums. Above 1.0 means your losses are worse and you pay a surcharge. Many public agencies and large GCs require an EMR below 1.0 or 0.85 to bid work. Your EMR is published annually by your state's workers' compensation rating bureau.
Training Completion Rate. The percentage of your workforce that is current on required training. This metric is increasingly tracked in prequalification questionnaires and feeds the "functioning safety management system" scoring in ESG frameworks. A company with 60% training compliance is demonstrating that a significant portion of its workforce is operating without required safety knowledge — which is both an OSHA violation and an ESG liability.
An important distinction: most contractors are not legally required to file ESG reports. There is no federal regulation that requires a 50-person mechanical contractor to publish an annual sustainability report. The requirement comes from the market — clients require it as a condition of the commercial relationship.
This means the practical obligation is: maintain the data that your clients will ask for, in a format you can produce on short notice. That means accurate OSHA 300 logs (which generate your TRIR and DART), current EMR documentation from your insurance carrier, up-to-date written safety programs, training completion records with timestamps, and documentation of how you investigate and close out incidents.
The gap most contractors discover when they first get a prequalification questionnaire is not that their safety performance is poor — it's that they don't have documentation to prove that it isn't. A company with a genuinely good safety record but no organized records will score poorly in a prequalification audit. The goal is to run the program in a way that generates documentation as a byproduct, not to create documentation retroactively when an audit request arrives.
EHS, Inc. manages contractor prequalification profiles on ISNetworld, Avetta, and Veriforce as a standalone service. This includes maintaining annual update submissions, uploading certificates of insurance, submitting written programs for platform review, and responding to client-specific questionnaires. Prequalification management is time-consuming and deadline-driven — clients post requirements on different schedules, platforms change their requirements annually, and a missed renewal can remove a contractor from an approved list without warning.
On the metrics side, Gerty — EHS, Inc.'s AI-powered compliance platform — runs the training and inspection programs that generate the completion data clients want to see. Training delivered by email, completion tracked automatically, records available for export. EHS, Inc. handles the OSHA recordkeeping that feeds TRIR and DART calculations, and advises on how to structure safety programs to meet specific client ESG requirements.
For contractors whose business depends on working for large operators or GCs, the ROI on getting this right is straightforward: the jobs you can bid, and the rates you can command, are directly tied to your safety record and your ability to document it.
