Maracá Ceramic Fuel Switching Project

Audit Analysis

The Maracá Ceramic fuel-switching project (VCS-455) is a VCS-registered energy project in Brazil that switches from non-renewable to renewable biomass for ceramic kilns. Additionality is confirmed by the VVB via a barrier test, leakage is quantified at 5%, and the project delivered roughly 92% of its pro-rata ex-ante expectation for the elapsed monitoring period. However, permanence risk is not explicitly addressed, no buffer pool is in place, the baseline is project-specific, and the low extraction confidence in the source documents introduces residual uncertainty.

Project Description

Red Flags

• ⚠Permanence / reversal risk is marked as 'not addressed' in the 2024 verification report and no buffer pool percentage is stated, leaving the reversion-to-non-renewable-fuel risk unquantified.
• ⚠The 2024 verification report lists 17 Corrective Action Requests (CARs) covering data inconsistencies (Qrenbiomass unit errors, PRy parameter sourcing) and the entrepreneur's difficulty proving renewable biomass origin, indicating recurring MRV data-quality issues.
• ⚠Minimum extraction confidence across the 56 source documents is rated 'low', meaning at least one key document was poorly readable and some extracted values may be unreliable.
• ⚠CORSIA eligibility and CCP status are both not stated in any available document, leaving dual-channel / double-claiming risk unassessed.
