A method of reducing NOx emissions of gas turbines in which supplementary compressed air streams are introduced into compressors of the gas turbine. The supplementary compressed air streams have a pressure higher than that of compressor air being used to support combustion within the combustor to enhance mixing of the compressed air streams with gaseous fuel and the compressor air. The compressed air stream and the supplementary compressed air streams are introduced into the combustors at a rate greater than that required to support combustion of the gaseous fuel to thereby lower flame temperature of the combustion and therefore the NOx emissions that would be otherwise produced by the combustion. A hydrogen containing stream can be introduced into the combustors along with the fuel to enhance flame stability of the combustion.
