# LEO debris cannot self-stabilize under any realistic deorbit compliance scenario because even 95 percent compliance only achieves stasis at 40000-50000 objects while business-as-usual doubles debris by 2050 and negative debris growth requires active removal of 60 large objects per year

Three independent modeling frameworks (Frontiers in Space Technologies 2026, OrbVeil 2026, ESA 2025) converge on the finding that LEO debris populations cannot self-stabilize through deorbit compliance alone. The stabilization scenarios show: (1) Business-as-usual with 80-90 percent compliance results in debris doubling by 2050; (2) High compliance at 95 percent or above achieves stasis at 40,000-50,000 objects but does not reduce the population; (3) Active debris removal (ADR) at 60+ large objects per year is required to achieve negative debris growth. The 60 objects/year threshold is scenario-dependent and described as illustrative rather than universal—more complex fragmentation cascades would increase the required removal rate. Current compliance rates are estimated at 80-95 percent, below the 95 percent threshold needed even for stasis. ESA's 2025 finding explicitly states that 'not adding new debris is no longer enough—active debris removal is required.' This directly falsifies the hypothesis that LEO can self-stabilize through improved operational practices alone. The finding has significant governance implications: compliance improvements buy time but do not solve the underlying accumulation problem, making ADR a structural requirement rather than an optional enhancement.


## Extending Evidence

**Source:** Frontiers in Space Technologies 2026

The paper explicitly states that even with 95%+ compliance with passive mitigation measures, debris population only achieves stasis at 40,000-50,000 objects, not reduction. The population of objects >10 cm is projected to more than double in less than 50 years even with current mitigation. This demonstrates that passive measures alone are structurally insufficient, and the 60-object/year active removal threshold is required for population reduction, not just stabilization.
