INSTITUTIONAL ESG DISCLOSURE
One journey. Multiple carbon identities
The same transportation activity can become Scope 1 for a fleet operator, Scope 2 through purchased mobility energy, Scope 3 for a customer or supplier, a national inventory record for government, and a mitigation outcome within a carbon market. The physical journey does not change. The accounting boundary does. Transportation Decarbonization Infrastructure preserves the underlying transportation evidence so these different carbon identities can be attributed without changing the physical event itself.

ACCOUNTING BOUNDARY
Scope is not a property of the vehicle. It is a reporting relationship
The same vehicle does not carry a permanent Scope classification. Its treatment depends on who owns or controls the operation, who purchases the energy, who contracts the transport service and whose value chain the activity serves. TDI maintains that relationship alongside the underlying transport evidence. Vehicle, fleet, charging, journey, carrier and activity records remain connected to the organizational boundary under which they are reported, preventing physical emissions data from becoming detached from the accounting logic that gives it meaning. A single transportation system therefore supports different reporting identities without changing the underlying environmental event.

Corporate disclosure depends on more than calculating emissions. Each result must remain connected to the activity that produced it, the organization responsible for reporting it and the Scope relationship under which it enters the account. TDI carries those relationships from source activity through calculation and disclosure.
Owned Fleet
Scope 1. Fuel combustion from vehicles owned or controlled by the reporting entity enters its direct emissions inventory.
Accounting Integrity
Recognition. Lifecycle. Markets.
Overlapping inventories
The same physical emission can legitimately appear in more than one company’s Scope 3 inventory. GHG Protocol explicitly warns that Scope 3 totals should therefore not be aggregated across companies to calculate regional emissions.
Boundary reconciliation
Disclosure regimes require emissions to remain connected to reporting boundaries, value-chain categories, financial information and materiality. ESRS, for example, requires Scope 1, 2 and significant Scope 3 categories and links emissions intensity back to net revenue.
Double claiming
International mitigation accounting is different. Under Article 6, corresponding adjustments are specifically used to prevent double counting when mitigation outcomes are transferred between Parties.
Double Counting as an issue
Not all double counting means the same thing.
The overlap in corporate Scope 3 inventories and double counting of sovereign mitigation outcomes are fundamentally different accounting problems. Transportation Decarbonization Infrastructure maintains the provenance connecting transportation activity, accounting recognition and subsequent environmental claims.
