BRT Bogotá, Colombia: TransMilenio Phase II to IV

Audit Analysis

The TransMilenio BRT project in Bogotá is a well-structured transport credit under CDM methodology AM0031, with a combined additionality test and a quantified (zero) leakage deduction. However, the available record is limited to a 2012 validation report and PDD, with no monitoring or verification data, no confirmed VVB additionality sign-off, and a project-specific baseline, leaving significant evidence gaps that constrain confidence in the claimed 4.05 million tonnes of CO₂ avoided.

Project Description

Red Flags

• ⚠No verification or monitoring report found in the extracted record; total verified ERR is absent, making it impossible to confirm actual delivery against the 4,052,426 tCO₂e lifetime claim
• ⚠Additionality test type is recorded as 'combined' but explicit VVB confirmation of the additionality assessment is not found in the available documents
• ⚠Minimum extraction confidence is rated low, indicating at least one key document was poorly readable, which undermines reliability of all extracted facts
• ⚠No buffer pool or permanence mechanism is documented for a project whose credits depend on continued BRT operation over seven years
