The Chennai Port is developing a green belt on 31 acre inside the port to reduce the carbon footprint, besides ensuring ambient air quality parameters to make the port a clean and green one. The authorities have planned to implement the Green Belt scheme in a systematic way.
The Union Ministry of Environment and Forests has released the revised National Ambient Air Quality Standards (NAAQS) 2009. As per these norms, both residential and industrial areas will have the same standards. The new standards include limits for benzene, ozone, benzo(a) pyrene, arsenic, nickel and ammonia, which were not covered in earlier standards notified in 1994.
