The present invention refers to a glass composition and a method for the commercial production of a solar control thin green glass mainly for use in the automotive industry such as symmetric-hybrid windshields or asymmetric-hybrid windshields, sidelights and rear windows, which includes a basic composition of soda-lime-silica glass, and consists essentially, in weight percentage: from 1.30 to 2.50% of total iron expressed as FeO; from 15 to 40% of Fe(Ferrous) and from 0.15 to 0.65% of FeO, expressed as FeO; from about 0.05 to about 0.30% of SO; from about 0.02 to about 1.0% of TiO; from about 0.0002 to about 0.03% of CrO; and from about 0.0002 to about 0.015% of CuO. The solar control thin green glass having an illuminant 'A' light transmission (T) greater than 70%, a direct solar transmittance (T) of less than 51%, a total UV light transmittance (T) of less than 40% and a total solar transmittance (T) of less than 63%; a dominant wavelength (λ) from 490 nm to 600; and excitation purity less than 7, for thickness from about 0.7 to 3.0 mm.
