What are the difference of RON 95 and RON 97 to environment?

RON 95 and RON 97 refer to different octane ratings of gasoline, with RON 97 having a higher octane rating, which allows for more efficient combustion in high-performance engines. The environmental impact of these fuels can vary; RON 97 typically burns more cleanly and may reduce engine knock, potentially leading to fewer emissions of pollutants. However, the overall environmental effects also depend on factors like fuel composition, vehicle efficiency, and driving conditions. Ultimately, while RON 97 may be slightly better for performance and emissions, the difference is marginal compared to the broader effects of fossil fuel consumption.
