A four-part forensic series introducing the Battery Break-Even Mileage metric and applying it to expose the grid-dependent, chemistry-dependent, and degradation-adjusted arithmetic that point-of-sale EV claims systematically omit.

Examines the institutional, industrial, and political economy reasons why BBM remains absent from every consumer-facing metric, subsidy framework, and legislative instrument — and what would change if it were required.

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.

Introduces the Battery Break-Even Mileage formula and applies it to five national grids and three battery chemistries, producing the matrix that inverts the universal 'EVs are always greener' claim.
