Volume of GHG and tailpipe gas emissions from the ethanol blend (assessed by the Bolivian government from 2022 to 2028) at the fuel consumption stage using the GREET ® model (Greenhouse Gases, Regulated Emissions and Energy Use in Transport), emissions will be expressed in grams of gas emission per kilometer of distance traveled, taking into account the following percentages of blend and gasoline (% v/v): Blend of 12% (2022), 16% (2023), 21% (2024), 25% (2025), 25% (2026), 25% (2027) and 25% (2028). Three main categories of vehicles were considered (Passenger cars, Light-Duty trucks SUVs and Light-Duty trucks) and three main subcategories based on the type of engine: Flexible fuel vehicles (FFV), Spark ignition direct injection vehicles (SIDI) and Hybrid vehicles (HEV).
