Energy, Emissions & Environmental Accounting Battery Lifecycle EV Carbon Accounting Manufacturing Emissions Grid Carbon Intensity Electric Vehicle Policy Design Trade-Offs & Optimization Limits Externalities & Lifecycle Displacement Power, Policy & Dependency Structures Systemic Fragility, Risk & Path Dependence
Shows how capacity fade over charge cycles increases the effective EV operational carbon per km, progressively extending BBM beyond its point-of-sale calculation — a dynamic effect no certification standard accounts for.

A four-part forensic series applying the Non-Exhaust Particulate Fraction (NEPF) metric to expose the tire, brake, and road abrasion emissions that dominate automotive PM₂.₅ output in both combustion and electric vehicles — entirely outside the regulatory frameworks that defined the transition to clean vehicles.

Introduces the Non-Exhaust Particulate Fraction (NEPF) and reveals why tire wear particles — including the salmon-lethal 6PPD-quinone compound — represent the dominant and unregulated PM₂.₅ output of all modern vehicles including battery-electric.
