Summary
This methodology quantifies the destruction of atmospheric nitrous oxide (N₂O) through the application of photocatalytic technologies on crop surfaces. It is designed for project activities that destroy ambient N₂O concentrations by converting it into inert nitrogen (N₂) and oxygen (O₂) via photocatalysis under natural light conditions.

Photocatalysis is a well-established chemical process, and this methodology supports the use of photocatalysts that can function under visible light. The methodology is technology-agnostic and may be applied to any photocatalytic formulation capable of breaking down N₂O under field conditions.
Photocatalysis is a well-established chemical process, and this methodology supports the use of photocatalysts that can function under visible light. The methodology is technology-agnostic and may be applied to any photocatalytic formulation capable of breaking down N₂O under field conditions.
The primary use case is in agricultural systems, where N₂O emissions are substantial and surface areas (such as crop canopies) are extensive and readily accessible for photocatalyst deployment. The photocatalyst can be applied using standard agricultural spraying equipment, integrated with regular farming operations to avoid additional environmental or operational burdens.

Monitoring of N₂O concentrations is conducted using air sampling techniques and trace gas analysers, such as gas chromatography or laser-based instruments. N₂O fluxes are calculated using standard equations incorporating atmospheric concentration data, wind speed, and crop canopy characteristics. Emission destructions are determined by comparing measured project fluxes against a baseline scenario representing standard agricultural practices without photocatalytic intervention.

Emission destructions are determined by comparing measured project fluxes against a baseline scenario representing standard agricultural practices without photocatalytic intervention.
Permanence of the emission destruction is ensured by the irreversible breakdown of N₂O into stable atmospheric gases. The methodology includes guidance on demonstrating additionality and establishing baselines in line with international best practices.
