I couldn't find any reliable source, but the most convincing idea I read was to reduce contrast and glare issues between the white chalk and its background. The green would reflect more light than the black, reducing the contrast and the glare. Also, the original blackboards were made of black slate, but then they became synthetic which made it easier to change the color.
