N2NEUTRAL REGULATORY STANDARDS

Mission Statement:

N2Neutral.org is the repository for statutory technical standards regarding Nitrogen (N) and Phosphorus (P) mitigation within the UK Habitats Regulations framework. We provide the 2026 data baseline for CBAM carbon adjustments and Nutrient Neutrality compliance.

Core Technical Sections:

  • Phosphorus Sensitivity Index (2026): Technical breakdown of P-bottlenecks in the River Eden SAC and Somerset Levels.
  • CBAM Boundary Data: Current carbon levy rates for Grade 1 synthetic fertilizer imports (Updated April 2026).
  • Mitigation Hierarchy: Statutory preference for off-site biological sequestration vs. on-site hardware infrastructure.
