Brascarbon Methane Recovery Project BCA-BRA-16

Audit Analysis

This is a registered VCS methane recovery project with VVB-confirmed investment-test additionality and no material findings reported in the monitoring record. However, several key items are weakly documented or inconsistent, especially leakage treatment, the absence of a stated usage-monitoring method, and conflicting figures and safeguard statements across documents.

Project Description

The purpose of this project is to mitigate and recover animal effluent related greenhouse Gas (GHG) by improving the Animal Waste Management System practices in the confined animal feed operations in the different cities located at the Mato Grosso do Sul state, central Brazil. In Brazil the agricultural operations related to the animals procedures are very wide and grow progressively and intensive to attend the worldwide food demand. Prior to the implementation of the project activity the animal wastewater, which consists of fresh water mixed with manure and urine accumulated in pits under or beside the barns, and was transported to one open lagoon for evaporation, fed by gravity pipeline systems. The organic material degraded in the primary treatment lagoon produced significant amounts of methane. These systems emit methane (CH4) resulting from anaerobic decomposition process. The swine livestock operations create profound environmental consequences, such as greenhouse gas emissions, odour and water/land contamination that result of storing animal waste, where this operation is not sustainable due to its severe environmental pollution. This project involved the construction of a new covered in-ground anaerobic reactors (digesters) that will utilize the organic material currently treated in the wastewater opened lagoon, of the confined animal operations to produce biogas. All manure will be sent daily directly to a digester not exceeding 24 hours in the barns. The methane is captured and flared to form CO2 which has a much lower climate impact compared with Methane. The plan is to use the flaring to also generate electricity in the future. No electricity will be consumed from the grid. The electrical parts that will be powered by energy will be supplied by solar cells and using rechargeable batteries.

Red Flags

• ⚠ Leakage is inconsistently described: the monitoring report says it was not addressed, while the validation report later says it was deemed negligible.
• ⚠ The verified emission reduction total differs across validation documents, and the project’s public claim-safety signals are incomplete because CORSIA eligibility and CCP status are not stated.

Credit Vintages

Cosa migliorerebbe questo punteggio

• Publish a reconciled emissions and leakage table that explains the difference between the earlier and later validation figures and clearly documents the final credited amount.
• Provide explicit usage-monitoring methodology, buffer pool treatment, and a clear statement on CORSIA eligibility and CCP status.
