How to Buy I-RECs for RE100 Compliance: A Complete Guide
As more companies commit to 100% renewable energy goals through initiatives like RE100, sourcing credible renewable energy certificates has become essential. One of the most widely used instruments is the International Renewable Energy Certificate (I-REC). For organizations looking to meet their sustainability targets, understanding how to buy RE100-compliant I-RECs is key.
This guide will walk you through the process.
1. What Are I-RECs?
The International Renewable Energy Certificate (I-REC) is a globally recognized attribute tracking system. Each I-REC represents 1 MWh of renewable electricity generated from sources like solar, wind, or hydro.
They provide organizations with proof of renewable energy consumption in regions where local renewable certificate schemes may not exist.
2. Why RE100 Compliance Matters
The RE100 initiative brings together leading companies committed to 100% renewable electricity. To count toward RE100 targets:
The I-RECs must come from approved renewable projects.
Certificates must meet RE100 technical criteria, including additionality, traceability, and proper retirement.
Reporting must align with RE100 disclosure guidelines.
In short, not all I-RECs automatically qualify. Choosing RE100-compliant I-RECs ensures your renewable claims stand up to international scrutiny.
3. Steps to Buying I-RECs for RE100
Step 1: Define Your Renewable Energy Targets
Understand how many megawatt-hours (MWh) you need to offset to reach your RE100 goals. This usually aligns with your total electricity consumption.
Step 2: Choose Eligible Sources
RE100 recognizes renewable sources like wind, solar, geothermal, and eligible hydro. Always verify that the I-RECs you buy come from these sources.
Step 3: Verify Certification
Work only with I-RECs issued under the I-REC Standard Foundation. Ensure they are properly documented, traceable, and retired in the registry to avoid double counting.
Step 4: Ensure RE100 Compliance
Check that the I-RECs meet RE100 reporting rules, including:
Project eligibility
Geographic relevance (close to where your operations consume energy)
Proper issuance and retirement within the same reporting year
Step 5: Buy From a Trusted Marketplace
Select a marketplace that provides transparent access to RE100-compliant I-RECs, with full documentation and impact reporting.
4. Benefits of Buying I-RECs
Global Applicability: Available in over 40 countries where local schemes are absent.
Transparency: Traceable via a central registry.
Credibility: Recognized by RE100, CDP, and GHG Protocol.
Flexibility: Suitable for both multinational corporations and regional companies.
