> Environmental institutions for UPSC: the National Green Tribunal (2010, benches, composition), the CPCB (1974), the Central Ground Water Authority, the EIA Notifications of 1994 and 2006 and the draft 2020, PARIVESH 2.0, CRZ and Eco-Sensitive Zones (353 notifications covering 496 Protected Areas). Includes practice questions, the real PYQs and exact Mains questions.

## How UPSC Tests Institutions and Clearances

🎯 **Exam priority: Tier-2. UPSC asks who sets up what, under which Act, and how a project gets clearance.** *UPSC asked how the National Green Tribunal differs from the Central Pollution Control Board (2018: the NGT was set up by an Act in 2010 and the CPCB is a statutory body constituted in 1974, so "executive order" is wrong), and which body was constituted under the Environment (Protection) Act (2022: the Central Ground Water Authority). Mains asked how the draft EIA Notification, 2020 differs from 2006 (2020), the role of environmental NGOs in EIA outcomes (2024) and the rehabilitation of human settlements as an environmental impact of major projects (2016).*

Keep two boxes: **the bodies** (who regulates and adjudicates) and **the clearance pipeline** (EIA, CRZ, ESZ).

## NGT, CPCB, CGWA and Other Bodies

## The institutions

| **Body**

 | **Origin and role**

 |
| Ministry of Environment, Forest and Climate Change (MoEFCC)

 | Administers the Water, Air, Environment (Protection), Wild Life, Forest Conservation, Public Liability Insurance and NGT Acts, among others

 |
| Central Pollution Control Board (CPCB)

 | Statutory body constituted on 23 September 1974 as the Central Board for the Prevention and Control of Water Pollution; renamed CPCB by the 1988 amendment (Act 53 of 1988) and given air pollution powers; funded by grant-in-aid from the Ministry

 |
| State Pollution Control Boards

 | Grant consents and enforce standards in States

 |
| National Green Tribunal (NGT)

 | Set up on 18 October 2010 under the NGT Act, 2010 for speedy disposal of environment and forest cases; Principal Bench at New Delhi and zonal benches at Pune, Kolkata, Bhopal and Chennai; a Chairperson with 10 to 20 judicial and 10 to 20 expert members; not bound by the Evidence Act, 1872, and applies sustainable development, precaution and polluter pays

 |
| Central Ground Water Authority (CGWA)

 | Constituted under Section 3(3) of the Environment (Protection) Act, 1986 to regulate groundwater development (2022 PYQ)

 |

 |

In August 2025 two judicial and four expert members were appointed to fill vacancies in the NGT.

## EIA, PARIVESH, CRZ and Eco-Sensitive Zones

## The clearance pipeline

- **EIA history:** first applied in 1978 to river valley projects, then to major public sector projects; the **EIA Notification of 27 January 1994** required clearance for 29 categories (later 32); the **2006 Notification** moved to impact-based assessment, more public participation and decentralisation, making clearance mandatory for **39 categories**.

- **Who clears:** Category A projects by MoEFCC on the recommendation of EACs; Category B by SEIAAs (State authorities); minor B2 projects are exempt from detailed EIA and public hearings. In 2025 airport expansions with valid clearances and no extra land were treated as B2.

- **In numbers:** **502** projects received environmental clearance in 2025; the average Central time was **64 days** against the 105 day limit.

- **PARIVESH** (launched 2018 as a single window for environment, forest, wildlife and CRZ clearances) became **PARIVESH 2.0**, with GIS tools, a Know Your Approval module and fully online appraisal and compliance monitoring.

- **Draft EIA Notification, 2020 (secondary sources):** proposed post-facto clearance for projects running without approval, a shorter public-hearing notice (30 to 20 days), exemptions from public consultation for some projects such as linear border projects and one annual compliance report instead of six-monthly reports. It drew heavy criticism; the 2006 Notification, as amended, is still the framework the Ministry's Annual Report 2025-26 describes.

- **Coastal Regulation Zone (secondary sources):** the CRZ Notification, 2019 divides CRZ-III by population density: densely populated areas (above 2,161 persons per sq km) get a 50 m no-development zone from the high tide line, others 200 m; the Centre clears CRZ-I and IV, States clear CRZ-II and III.

- **Eco-Sensitive Zones (ESZs):** regulate development around Protected Areas. **353 final ESZ notifications covering 496 Protected Areas** have been issued, compared with 23 covering 25 until 2014.

## How UPSC Could Ask This Next

- **Origin:** which body is statutory, constitutional or executive and under which Act.

- **NGT facts:** benches, composition and principles.

- **EIA:** categories A and B, the 1994 and 2006 notifications, the draft 2020.

- **CRZ and ESZ:** which authority clears what and what is prohibited.
