To operate an industry in India, manufacturers are required to obtain an NOC from the Pollution Control Board before beginning their operations. The Central Pollution Control Board (CPCB) and respective State Pollution Control Boards (SPCBs) classify industries based on the amount and type of pollution they emit. This classification system is defined under the Water (Prevention & Control of Pollution) Act, 1974 and the Air (Prevention & Control of Pollution) Act, 1981, ensuring that industries follow environmental regulations to minimise adverse impacts.

According to the Pollution Control Board, industries are categorised into four main types: Red, Orange, Green, and White. Those falling under the Red, Orange, and Green categories must obtain a Consent to Establish (CTE) and a Consent to Operate (CTO) from the relevant authorities. These consents act as mandatory approvals to ensure that businesses function within prescribed pollution control norms. On the other hand, industries listed under the White category are exempt from securing such approvals, as they are considered non-polluting and environmentally safe.

At GRC India, our compliance experts assist organisations in obtaining their NOC from the Pollution Control Board across Delhi NCR and other regions of India.
