Renewable Energy Certificates - A Practitioner's Guide to RECs, I-REC Standard, and Corporate Procurement

Description
A Technical Reference on Renewable Energy Certificates from a Practitioner's Perspective 

Most introductory content on Renewable Energy Certificates (RECs) covers the basics: "buy RECs to support renewable energy claims." This guide goes deeper. Written from the perspective of a practitioner who has integrated REDEX (a Southeast Asian REC platform) with Evident (the I-REC Standard registry operator), it walks through the technical mechanics that determine whether a REC purchase actually delivers a defensible Scope 2 emission reduction claim.

WHO THIS GUIDE IS FOR
✅ ESG and sustainability professionals preparing reports under GHG Protocol, RE100, SBTi, or CDP
✅ Energy procurement managers evaluating renewable electricity sourcing
✅ Corporate finance and treasury teams assessing REC cost and risk profiles
✅ Renewable energy project developers issuing RECs as a revenue stream✅ Consultants and advisors supporting clients on Scope 2 emission reductions
✅ Multinational corporates with operations in Southeast Asia

WHAT MAKES THIS DIFFERENT

Most REC content available online is either marketing material from brokers or generic compilations from research. This guide stands out because:

📌 Insider perspective on registry mechanics — Evident, I-REC issuance flow, and how platforms integrate with registries (the layer most guides skip entirely)
📌 Honest treatment of pitfalls — vintage mismatch, double counting, claim location vs generation location, additionality debates
📌 Southeast Asia / Vietnam focus — DPPA mechanism, PDP 8 context, I-REC market dynamics in SEA (rare in English-language content)
📌 Framework-by-framework coverage — exactly how RECs work under GHG Protocol Scope 2, RE100, SBTi, CDP, and emerging EU CSRD/ESRS rules

📌 Forward-looking — 24/7 Carbon-Free Energy, granular certificates, market maturation trends
