Tamil Nadu government announced a new initiative, 'Direct CTO', to enable companies operating under 'green category industries' receive faster clearances from government to commence operations. The move would largely benefit micro, small and medium enterprises planning to set up operations in the state, to mark 125 years of trade body Confederation of Indian Industry (CII). The pollution index of any industrial sector is a number from 0 to 100 and the increasing value of PI refers to the degree of pollution load from the industries. 'Red' category industries are those which have a pollution index score of 60 and above, 'orange' category are with 41 to 59, 'green' category industrial sectors are of 21 to 40 and 'white' category industries are from 0 to 20.
