Hon Jo Luxton to the Minister of Agriculture: What evidence, if any, exists to show that nitrification inhibitors can reduce N2O emissions from urine and dung deposited on pastures by up to 30%, as stated by New Zealand’s second emissions reduction plan 2026–30, and how is this being considered in New Zealand's overall methane reduction approach?

Hon Todd McClay: Potential rates of emissions reductions from the use of nitrification inhibitors stated in the Second Emissions Reduction Plan 2026-30 were based on estimates by researchers and subject matter experts in 2024.
