The carbon signals installed at every State provide the information to citizens easily as its lamp would turn red to show the increase in the emission if the carbon emission exceeds the monthly targeted emission level, while it would turn yellow if the emission falls within the targeted range, and it changes to green color if the emission is below the targeted level.
