Buy I-REC Certificates Through Hestiya's Verified Global Marketplace
Hestiya is a trusted I-REC provider network, connecting corporate buyers directly to verified suppliers across 60+ countries. Hestiya is not an issuer itself.
A Transparent Way to Source Renewable Energy
Businesses looking to buy I-REC Certificates need a fast, transparent way to source them without chasing individual generators or brokers market by market. Hestiya solves that by connecting buyers to a global network of verified suppliers on a single marketplace. Every listing is tied to a certificate legitimately issued under the I-REC Standard, so what you buy is ready to retire against RE100, CDP, or GHG Protocol Scope 2 reporting. Pricing is visible upfront, delivery is fast once a transaction clears, and coverage spans solar, wind, hydro, and biomass generation across dozens of countries.
What Are I-REC Certificates and Why Businesses Buy Renewable Energy Certificates
An I-REC (short for the International REC Standard) is an Energy Attribute Certificate (EAC) that represents one megawatt-hour of electricity generated from a renewable source and tracked to a single buyer, preventing that same megawatt-hour from being claimed twice. Businesses buy renewable energy certificates like I-RECs to make a verifiable claim that some or all of the electricity they consume was sourced from renewable generation: a claim that matters directly to regulators, investors, and customers evaluating a company's climate commitments.
Corporate Procurement Goals
Companies typically purchase renewable energy certificates for one of three reasons: to meet a corporate renewable electricity commitment such as RE100, to reduce reported Scope 2 emissions under the GHG Protocol's market-based method, or to support ESG disclosures for frameworks like CDP. Because I-RECs cover markets outside North America and Europe, they are typically the only credible option for claims tied to electricity consumed in Asia-Pacific, Latin America, the Middle East, and Africa.
How I-RECs Support RE100 & Scope 2
Under the GHG Protocol's Scope 2 Guidance, companies report electricity emissions two ways: a location-based figure and a market-based figure. Retiring an I-REC that meets the GHG Protocol's Scope 2 quality criteria (correct vintage, matched market boundary, no double counting) lets a company lower its market-based Scope 2 number. RE100's own Technical Criteria explicitly recognise I-RECs as valid instruments to evidence 100% renewable electricity sourcing. See how I-RECs improve ESG ratings here.
I-REC vs REC vs GO: Key Differences
I-RECs, RECs, and GOs are all Energy Attribute Certificates that serve the same basic purpose, but each applies to a different region, and using the wrong one for a given claim can invalidate it.
| Instrument | Region Covered | Governed / Administered By |
|---|---|---|
| REC (Renewable Energy Certificate) | United States and Canada | Regional registries, including WREGIS, NEPOOL-GIS, PJM-GATS, M-RETS, ERCOT, and NC-RETS; 1 REC = 1 MWh |
| GO (Guarantee of Origin) | European Union / EEA | EU Renewable Energy Directive framework; cross-border transfer via the Association of Issuing Bodies (AIB) and the EECS standard |
| I-REC | 60+ countries outside the US/Canada and EU/EEA: Asia-Pacific, Latin America, Middle East, Africa | I-REC Standard, governed by the I-TRACK Foundation; Evident operates the primary registry as an Accredited Code Manager |
Together, the three families give near-global coverage for market-based renewable electricity claims, which is why a multinational buyer typically ends up sourcing all three, not just one.
Purchase I-REC Certificates from Verified Suppliers on Hestiya
Once you know what to buy, the next question is who to buy it from. You can purchase I-REC Certificates on Hestiya from suppliers that have already been checked against I-REC Standard issuance records, so you're not left validating a certificate's legitimacy on your own after the fact.
How Hestiya Verifies Every Supplier
Every listing on Hestiya is cross-checked against the issuing registry before it goes live, confirming the certificate exists, hasn't already been retired or sold elsewhere, and is tied to an accredited Local Issuer. See our guide: How to Buy Good Quality I-RECs.
Technologies Covered
Listings span the generation technologies most corporate buyers need to match against their own consumption profile, from utility-scale solar and wind through run-of-river hydro and biomass.
Countries and Regions Covered
Supply spans I-REC participating markets across Asia-Pacific, Latin America, the Middle East, and Africa, including high-demand sourcing markets such as India, Brazil, Mexico, Vietnam, Thailand, Malaysia, Chile, Colombia, Nepal, and Turkey.
Supplier Vetting Process
Suppliers are onboarded only after their generation assets and issuance history are checked against registry records, and listings are monitored on an ongoing basis rather than verified once and left unchecked. Read more about how carbon trading works.
I-REC Procurement Process
An I-REC procurement cycle on Hestiya follows three simple steps whether you're buying a single vintage for one facility or running corporate procurement across a multi-country portfolio.
Define Volume, Technology, Region
Start with the MWh volume you need to cover, matched to the country and, where required by your reporting framework, the specific generation technology.
Compare Verified Listings
Filter live listings by country, technology, and vintage, and compare pricing across verified suppliers side by side. Every listing has already been checked against registry records.
Transact, Retire, and Report
Complete the transaction, retire the certificate against your consumption or claim, and keep the transaction documentation for your Scope 2, RE100, or CDP disclosures.
I-REC Pricing and Market Data
I-REC Prices Are Not Fixed
They move with regional supply, demand, technology mix, and vintage availability, which makes real-time data more useful than a static rate card when budgeting a procurement cycle. See structural shifts in markets 2025-2026.
What Drives Prices by Country & Tech
Markets with abundant solar or wind generation tend to price lower than supply-constrained hydro or biomass markets. Hestiya's recent analysis breaks down Vintage 2025 and 2024 I-RECs.
I-REC Solutions for Corporate and Enterprise Buyers
Beyond one-off purchases, Hestiya offers I-REC Solutions built for sustainability teams managing recurring, multi-market renewable electricity claims year over year.
Bulk & Recurring Procurement
Enterprise buyers with large or recurring volume needs can structure purchases across multiple markets and vintages rather than transacting by listing, simplifying budgeting and supplier relationships.
