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.
Current Statutory Catchment Status (Q2 2026)
| Catchment | Statement | Trigger Metric |
| River Eden (Carlisle) | Unlocked | 05 Feb 2026 Boundary Revision |
| The Solent | Critical (P) | Phosphorus Surplus Limit (PSL) |
| Somerset Levels | Stalled | High-Density Nitrate Saturation |
Project Audit Request
Due to the high sensitivity of the River Eden SAC and the Phosphorus (P) Bottleneck identified in April 2026, N2Neutral provides technical offset reviews for stalled developments.
To request an audit of your project’s nutrient requirements or to identify available off-site mitigation credits, please contact the standards office:
