The conundrum of Costa Rica's plan for a gasoline cocktail
A mix of gasoline and ethanol does not convince several sectors of the Costa Rican economy, basically because there are doubts about its impact on the environment.
The government is aiming to reduce its carbon footprint by adding 10 percent of ethanol to regular gasoline. The mix provides more power and torque to the motor, says the state refining company Recope.
However, there are concerns over the cost of the mix, which would cost more to consumers. In addition, there are concerns that ethanol might be much less effective in helping the environment than do other biofuels, La República reports in Spanish.
