# Environmental Credits & 24/7 Carbon Accounting

OpenVPP supports real-time, granular generation and tracking of:

* Renewable Energy Certificates (RECs)
* Carbon Offsets and Avoided Emission:
* Energy Attribute Certificates (EACs)

Each unit of renewable energy generated is cryptographically signed at the smart meter

and issued as a tokenized certificate, complete with time-stamped metadata. This enables:

**24/7 Carbon Accounting**: Regulators and market participants can match energy consumption with renewable production on an hourly basis, supporting compliance with emerging hourly matching policies.

**Automated Auditing**: Certificates are immutable, verifiable, and tied to physical meter data, simplifying reporting under ESG and regulatory frameworks.

**Cross-Border Compliance**: OpenVPP’s open, standards-based design facilitates alignment with international credit schemes such as GHG Protocol, I-REC, and VERRA.
