P Project 2025

Summary

Project results comparing three target scopes (N Only, N+P, P Only) under three model variants:

• Old Retention
• New Retention
• New Retention + Differentiation

The central comparison workbook is TargetEcon_Scenario_Comparison_v4.xlsx.

Cross-run findings

• N+P is the only scope with a material national cost saving from New Retention relative to Old Retention: -3.58 mDKK/yr.
• Adding Differentiation partly offsets that saving in N+P (+1.65 mDKK/yr vs New Retention) but the run still remains cheaper than Old Retention by 1.92 mDKK/yr.
• N Only costs are almost unchanged by the retention/differentiation updates, but total selected area rises sharply from 595.7 kha to roughly 634–635 kha.
• P Only costs stay almost flat around 299.2–299.5 mDKK/yr, while N side-effects increase from 1.325 kt N/yr to about 1.43 kt N/yr.
• Across all scopes, the cost structure is still dominated by FO, LRh, WL, and MW(VP3) rather than by the pure P measures alone.
