NOx PM and CO₂ Emission Reduction in Fuel Combustion Processes

<p>Nowadays fossil fuels are still the main source of primary energy in power generation transport and industry in general. Therefore issues regarding environmental protection and in particular air protection are of great importance. Hence they have become a key part of the global policies of most developed countries. This<em> </em>Special Issue of <em>Energies</em> entitled NOx PM and CO<sub>2</sub> Emission Reduction in Fuel Combustion Processes deals with various methods and reduction technologies targeting pollutant emissions especially NOx CO<sub>2</sub> and particulate matter associated with different fuel combustion processes. This topic is focused mainly on conventional hydrocarbon fuels; however we consider biofuels as well.</p>
