ESG & Sustainability Credentials
Prove Your Sustainability Commitments With Tamper-Proof Credentials
Blockchain-verified certificates for ESG training, carbon programmes, and sustainability credentials. Immutable proof that stands up to audit rather than another PDF that stands up to Photoshop.
TL;DR
A sustainability certificate is only evidence if someone outside your company can confirm it. TRUE issues ESG and sustainability training certificates as verifiable documents: a cryptographic fingerprint of each one is written to blockchain at issuance, the certificate is hosted on your own domain, and an auditor scans the QR code to see who completed which training on which date. Issuing runs automatically from your LMS, and revocation updates the verification status immediately when a requirement changes. The point is documentation an auditor can check without taking your spreadsheet on trust.
- Auditors verify by scanning, with no login and no request to your ESG team.
- Records cannot be edited after issuing, which is what a PDF cannot promise.
- Issuing and revocation run through the API, so the evidence stays current.
What does sustainability reporting require you to prove?
That the training happened, to named people, on a date, in a form a third party can check. Saying a programme ran is not evidence, and a PDF certificate is not evidence either, because it can be edited after the fact. The four gaps below are the ones auditors open first.
The EU's Corporate Sustainability Reporting Directive (CSRD) has changed the rules. It's no longer enough to say your team completed ESG training. You need to prove it, with documentation that auditors can trust.
- PDFs can be fabricated. A PDF certificate proving ESG training completion can be edited in minutes. When auditors can't distinguish genuine training records from altered ones, your documentation is worthless.
- No audit trail. Who completed what training, when, verified by whom? Most organisations track this in spreadsheets or email folders. Auditors aren't impressed.
- Greenwashing risk is real. If your sustainability credentials can't be independently verified, they look like exactly what sceptics accuse you of: marketing, not commitment.
- Regulatory scrutiny is increasing. CSRD, EU Taxonomy, and related directives require documented, verifiable proof of sustainability efforts. The bar is rising every reporting cycle.
The gap between "we trained our people" and "here's immutable proof our people were trained" is the gap between passing and failing an ESG audit.
How much sustainability documentation holds up when it is checked?
Less than companies expect. When the European Commission examined environmental claims, most were vague or unsupported, which is the reason scrutiny moved from statements to evidence. Reporting duties themselves narrowed in 2026, but the companies still in scope, and everyone in their supply chains, now face a higher standard of proof rather than a lower one.
- 53% of green claims give vague, misleading or unfounded information, and 40% have no supporting evidence at all. Source: European Commission, Green claims, drawing on its 2020 study of environmental claims in the EU.
- Since 24 February 2026, CSRD reporting applies to undertakings with more than 1,000 employees and net turnover above 450 million euro. Directive (EU) 2026/470 narrowed the scope and was published in the Official Journal on 26 February 2026. Source: EUR-Lex.
- More than 500,000 documents have been issued through TRUE for over 200 organisations in more than 15 countries. Source: TRUE platform data.
Fewer companies file a report. The ones that do, and the suppliers they ask for data, still have to show that a named person completed a named course on a named date.
How do verifiable certificates close the evidence gap?
By moving the proof onto the document. Each certificate carries a cryptographic fingerprint anchored on blockchain and a QR code that opens a verification page on your domain, so the auditor confirms it directly rather than asking you to confirm it.
Immutable Blockchain Proof
Every training certificate is written to four blockchains: Ethereum, AVAX, Fantom and Polygon. A cryptographic hash of the document is permanently recorded. Change a single detail after issuance and the hash won't match. This isn't a database entry that can be edited. It's an immutable timestamp and fingerprint on decentralised infrastructure maintained by thousands of independent nodes.
Instant QR Verification
Every certificate includes a QR code. An auditor, regulator, or stakeholder scans it with their phone and sees the verified original, with issuer identity, training details and completion date confirmed against the blockchain record. No phone calls. No spreadsheets. Verification in seconds.
eIDAS Compliant
TRUE meets the EU's eIDAS regulation for electronic identification and trust services. Your ESG training certificates carry legal weight in the regulatory context that matters most: European compliance reporting.
Automated Issuance via API
TRUE's REST API connects to your LMS, HR system, or training platform. When an employee completes ESG training, the certificate issues automatically, blockchain-secured, branded and delivered without manual intervention. Scale from 50 certificates to 5,000 without adding headcount.
Your Domain, Your Brand
Certificates live on your domain, credentials.yourcompany.com. When employees share their ESG credentials on LinkedIn or present them during audits, your organisation's commitment to sustainability is front and centre.
Full Analytics and Audit Trail
Track every certificate: when it was issued, when it was opened, when it was verified, and by whom. A complete audit trail that documents not just training completion, but engagement with the credentials.
Which sustainability credentials can you issue?
Carbon programme completions, ISO 14001 and EU Taxonomy training, DEI and human rights training, governance and board training, sustainability awards, and supplier certification. Anything you may later have to evidence to an auditor, a client or a procurement team.
Carbon credit and offset programmes
Issue verifiable certificates for carbon credit training, verification, and certification. Blockchain immutability ensures carbon programme credentials can't be questioned.
ISO 14001 and EU Taxonomy training
Document completion of environmental management and taxonomy alignment training with tamper-proof certificates that satisfy reporting requirements.
DEI and human rights training
Prove completion of diversity, equity, inclusion, and human rights training programmes. Verifiable certificates show commitment that someone outside the company can check.
Governance and board training
Issue blockchain-secured certificates for governance training and board-level ESG education. Documentation that stands up to shareholder scrutiny.
Sustainability awards and recognition
Certify organisations and individuals for sustainability achievements with credentials that recipients share, which carries your programme further.
ESG supplier certification
Verify that supply chain partners have completed required sustainability training. QR verification lets procurement teams check supplier credentials instantly.
The gap between ESG commitment and ESG proof is a documentation problem. Blockchain-secured certificates close it.
Who benefits from verifiable ESG certificates?
Four groups, for different reasons. ESG managers get evidence that survives an audit, employees get a credential worth keeping, auditors get a record they can check themselves, and leadership gets a defence against the greenwashing charge.
For ESG Managers
Automate certificate issuance from your training platform via API. Maintain an audit-ready record of all ESG training across the organisation. Stop chasing spreadsheets before audit season.
For Employees
Own your ESG credentials. Share them on LinkedIn. Add them to your professional profile. A blockchain-secured sustainability certificate is a career asset as well as a compliance record.
For Auditors
Verify any certificate independently via QR code or the verification portal. Blockchain confirmation provides the integrity assurance that PDFs cannot. eIDAS compliance means the documentation meets EU electronic document standards.
For Leadership
Anti-greenwashing protection, built into your training documentation. When stakeholders or regulators question your sustainability commitments, point to immutable, independently verifiable proof.

What do ESG teams ask before switching?
Whether the certificates count as audit evidence, how an auditor checks one, how issuing automates from an LMS, how personal data is handled, and what happens when requirements change.
Can TRUE certificates be used as evidence in CSRD sustainability reporting?
TRUE certificates provide blockchain-secured, independently verifiable proof of training completion. They serve as strong documentation for ESG training programmes. However, specific CSRD reporting requirements vary by organisation and scope. TRUE provides the verifiable credential layer, not regulatory advice.
How does blockchain verification work for auditors?
Every certificate has a QR code. The auditor scans it with any smartphone. No special software is needed. The verification page confirms the certificate details against the blockchain record: issuer, recipient, training completed, date, and authenticity status.
Can we automate certificate issuance from our LMS?
Yes. TRUE's REST API integrates with Canvas, Moodle, Learnster, Salesforce, and custom systems. When an employee completes ESG training, the certificate issues automatically, blockchain-secured, branded and delivered to the recipient.
Are TRUE certificates GDPR compliant?
TRUE is a Swedish company with GDPR-native architecture. Employee personal data is handled per EU data protection standards. Data stays in Europe.
Can we revoke or update certificates if training requirements change?
Yes. TRUE supports programmatic revocation through the API. If a certification expires or requirements change, you can revoke or update credentials, and the verification status updates immediately for anyone checking.
What do TRUE customers say?
Organisations issuing verifiable documents through TRUE, in their own words.
“Thank you for your support and great cooperation TRUE. Our help contributes to our work for an equal world, free from violence and discrimination against women and girls.”
“For us, it’s only natural to collaborate with the player in secure document management that has the highest quality, and stands for world-class security.”
