How Much can e-LRTs Reduce Greenhouse Gas Emissions?


The Role of Rail Transit Systems in Reducing Energy and Carbon Dioxide Emissions: The Case of The City of Rio de Janeiro (16 page pdf, Carlos Eduardo Sanches de Andrade  and Márcio de Almeida D’Agosto, Sustainability, Feb. 5, 2016)

Today we review a paper that uses a model to estimate the GHG emissions avoided by shifting urban transportation mode from passenger car to electric rail transit as a test case for Rio de Janeiro, Brazil, a city of 6.5M, projected over the period from 2016 to 2040. The amount of GHG emissions avoided were 55,449 tonnes per year for the city or 44.53 grams per passenger kilometer. Although cars in Brazil use more ethanol in their fuel than elsewhere and this is accounted for here, many of the assumptions made to model the shift could be applied to other cities.
