Analysis

The El Dorado Nitrogen N2O abatement project is a long-operating technology-based project with VVB-verified additionality and a measured project-specific baseline, but it is undermined by a complete absence of leakage documentation, a contradiction on whether N2O capture is legally mandated, numerous calibration and data-quality findings across multiple reporting periods, and a low extraction confidence rating that limits assurance in the extracted record.

  • Removal or reduction

    Emission reduction or avoidance

    Prevents or reduces emissions — fits contribution claims, not SBTi neutralisation.

  • Paris Agreement (Article 6)

    No Article 6 authorization

    No corresponding adjustment: the host country can also count this reduction towards its own target.
