Abstract

The Troc Carbone Avion (TCA) (Airplane Carbon Exchange) mechanism is a sort of Personal Carbon Trading (PCT) system for allocating emissions allowances to French air travelers, combined with an exchange mechanism at the carbon price of €100 in the first year, which then follows the price growth trajectory defined in the Quinet II report for subsequent years. It can also be described as a hybrid carbon tax/subsidy mechanism with a threshold. Based on the latest available data, each French citizen would have an emission allowance of 0.4 tons of carbon in the first year. The operating procedure is an app similar to the TousAntiCovid app, with a QR code required at check-in by airlines to obtain a boarding pass. The personal carbon account is reserved to French nationals or residents of France. We estimate that the TCA could lead to a 6 percent reduction in total emissions in the first year, for a market exchange value of around €1.5 billion. The TCA is also a transfer mechanism that redistributes purchasing power essentially from the top decile to the bottom decile of the income distribution, which could see its purchasing power increase by 0.5%. We also propose a variant of the TCA mechanism to make it consistent with the EU's Emissions Trading System (ETS).
