Análise preliminar do custo-benefício no adiantamento da implantação do diesel B-20 na cidade do Rio de Janeiro

Abstract

The present study seeks to identify the economic impacts associated with the adoption of a 20% biodiesel utilization model in the current fuel used by public urban buses in the city of Rio de Janeiro, as established by Municipal Decree No. 44.210 / 2018. To do so, data related to the sector was raised and the additional cost related to the logistics, production, and depreciation factors inherent to this conversion was identified. In addition, this cost was compared with that related to the acquisition of carbon credits sufficient to neutralize carbon dioxide emissions in the order of magnitude found in a scenario in which the conversion to the concentration studied is implemented in order to identify the inherent economicity whether or not the conversion is being considered. The results show that the benefits of reducing greenhouse gas emissions, measured by current market prices, account for about three-quarters of the additional costs of implementing the program, which also brings other social benefits such as reduction of toxic gas emissions and local pollution, and lower hospital costs due to lower incidence of respiratory, allergic, cardiovascular, neurological, and lung cancer diseases.
