ESG Compliance: Prove Without Revealing

intermediate6 min

The ESG Reporting Problem

Companies face increasing pressure to report Environmental, Social, and Governance (ESG) metrics. But disclosing raw data creates competitive risk — exact emission figures, diversity numbers, and governance scores are sensitive.

Zero-knowledge proofs let you prove compliance without disclosure.

Example: Carbon Emission Threshold

Scenario: You need to prove to a regulatory body that your annual CO2 emissions are below 10,000 tonnes.

Circuit:

{
  "name": "Carbon Compliance",
  "inputs": {
    "public": ["threshold"],
    "private": ["actual_emissions"]
  },
  "gates": [
    { "type": "gt", "inputs": ["threshold", "actual_emissions"], "output": "compliant" }
  ],
  "outputs": ["compliant"]
}

Public input: threshold = 10000

Private input: actual_emissions = 7,342 (never revealed)

The proof confirms compliance. The regulator sees "compliant = true" and a valid STARK proof. They never see 7,342.

Example: Diversity Target Range

Scenario: Prove your board diversity percentage falls within a target range (30-50%) without revealing the exact number.

Circuit:

{
  "name": "Diversity Range",
  "inputs": {
    "public": ["min_pct", "max_pct"],
    "private": ["actual_pct"]
  },
  "gates": [
    { "type": "range", "inputs": ["actual_pct", "min_pct", "max_pct"], "output": "in_range" }
  ],
  "outputs": ["in_range"]
}

Why This Matters

1.**Regulatory compliance** — Prove you meet standards without disclosing competitive data

2.**Audit efficiency** — Auditors verify proofs mathematically, reducing time and cost

3.**Trust without transparency** — Stakeholders get assurance without access to raw numbers

4.**Tamper-proof** — Proofs are cryptographically bound to the claim. You can't forge compliance.

Try It

1.Go to [Templates](/templates) and select an ESG-related template

2.Enter your threshold as a public input

3.Enter your actual data as a private input

4.Generate and verify the proof

The entire process takes under 30 seconds.
