Carbon Price Efficiency Lock-in and Path Dependence in Urban Forms and Transport Infrastructure

21 June 2014 - Special issues

By Paolo Avner ,Jun Rentschler, Stéphane Hallegatte

This paper investigates the effect of carbon or gasoline taxes on commuting-related CO2 emissions in an urban context. To assess the impact of public transport on the efficiency of the tax, the paper investigates two exogenous scenarios using a dynamic urban model (NEDUM-2D) calibrated for the urban area of Paris: (i) a scenario with the current dense public transport infrastructure, and (ii) a scenario without. It is shown that the price elasticity of CO2 emissions is twice as high in the short run if public transport options exist.

    Banque de France and I4CE become climate finance partners

    The Banque de France and I4CE are forming a partnership with the objective of enhancing the consideration of climate risks and opportunities by the financial sector. This partnership aims to facilitate the exchange of expertise between the two institutions, and more generally the interactions between researchers, financial sector actors, and public authorities. It will also support the work of the Banque de France within the Central Banks and Supervisors Network for Greening the Financial System (NGFS) that it launched at the One Planet Summit in December 2017.
