The Indian Green Building Council along with Ministry of Commerce & Industry has prepared the Green SEZ guidelines. The feedback and suggestions of several stakeholders were sought during interactions held at various major cities - New Delhi, Cochin, Mumbai, Hyderabad and Noida. The IGBC Green SEZ Rating System is an extension of the Green SEZ guidelines. The rating system encourages the projects to surpass the requirements of many codes and standards. The rating programme is a tool which enables the designer to apply green concepts and criteria, so as to reduce the environmental impacts, which are measurable. The programme covers methodologies to cover diverse climatic zones and changing lifestyles.
