What effect does higher combustion efficiency have on environment?

Higher combustion efficiency leads to a more complete burning of fuel, resulting in more energy being extracted from the same amount of fuel. This improved efficiency reduces the quantity of unburned hydrocarbons and other pollutants released into the atmosphere, thereby decreasing overall emissions of harmful substances. As a result, there is less energy wasted in the form of exhaust gases and lower greenhouse gas emissions contributing to climate change. Furthermore, with more effective utilization of fuel, the reliance on fossil fuels diminishes, since less fuel is required to produce the same amount of energy. Overall, striving for higher combustion efficiency is a critical step toward reducing a facility's environmental impact.
