The Quarterly Carbon Market Report (QCMR) is the leading source of data on Australia’s carbon markets. It provides a regular view of supply and demand across the markets supporting the schemes we administer. This includes:
- Australian carbon credit units (ACCUs) and Safeguard Mechanism credit units (SMCs)
- large-scale generation certificates (LGCs)
- small-scale technology certificates (STCs).
QCMRs outline:
- key factors influencing market performance
- trends and opportunities that may influence market decisions
- topics specific to unit and certificate types in separate chapters.
The Australian environmental markets chapter includes ACCU project registrations, issuance and demand. The large-scale renewable electricity chapter includes investment, approval and generation of large-scale renewable energy. The Small-scale Renewable Energy Scheme chapter includes uptake of rooftop solar, household batteries, and energy efficient technology.
