Analysis

The Rio Grande Valley Landfill is a long-running CAR methane project with VVB-confirmed additionality and a conservative delivery rate (87.5% of pro-rata ex-ante expectation), but it is held back by a project-specific modeled baseline, unaddressed leakage, and a history of significant instrument calibration and data-quality issues that required corrective actions. The most recent verification (August 2026) confirms all prior findings were resolved, yet the absence of quantified leakage treatment and several unstated monitoring parameters limit confidence in the credit's robustness.
