The Carbon Balance of a High Speed Line Michel LEBOEUF SNCF, Director for Major Projects & Prospective France 1/27
Introduction: Three received wisdoms about trains running faster: - they are more energy consuming, - they are more harmful for the environment - they are more expensive. So... What s the point of increasing the commercial speed? 2/27
Demonstration 1 Carbon balance of a rail high speed line How to assess it? 2 Impact of a speed increase on the carbon balance It takes CO 2 to save CO 2 and... 3 The cost of speed... it takes money to make money. 3/27
