Which of the following best describes/describe the aim of ‘Green India Mission’ of the Government of India?
1. Incorporating environmental benefits and costs into the Union and State Budgets thereby implementing the ‘green accounting’.
2. Launching the second green revolution to enhance agricultural output so as to ensure food security to one and all in the future.
3. Restoring and enhancing forest cover and responding to climate change by a combination of adaptation and mitigation measures.
Select the correct answer using the code given below:

The correct answer is 3 only.

To understand why, let us carefully examine the Green India Mission (GIM) — one of the eight missions under India's National Action Plan on Climate Change (NAPCC), launched in 2014 — and evaluate each statement one by one.

What is the Green India Mission?
The Green India Mission aims primarily at protecting, restoring, and enhancing India's forest and tree cover, while simultaneously addressing climate change through both adaptation and mitigation strategies. It recognizes forests as a critical carbon sink and a vital ecosystem service provider.

Statement 1: "Incorporating environmental benefits and costs into Union and State Budgets (green accounting)."
This statement does NOT describe the Green India Mission. Green accounting or the incorporation of environmental costs into national budgets is associated with a different NAPCC mission — the National Mission for a Green India does not cover fiscal/budgetary accounting. Green accounting concepts are related to broader economic policy frameworks and the National Statistical Commission's initiatives. Therefore, Statement 1 is incorrect in the context of GIM.

Statement 2: "Launching the second green revolution to enhance agricultural output for food security."
This statement is also incorrect for the Green India Mission. The goal of enhancing agricultural output and food security is specifically the objective of a different NAPCC mission — the National Mission for Sustainable Agriculture (NMSA). The Green India Mission has nothing to do with launching a "second green revolution." Therefore, Statement 2 does not apply to GIM.

Statement 3: "Restoring and enhancing forest cover and responding to climate change by a combination of adaptation and mitigation measures."
This statement is precisely and completely correct. The Green India Mission has the following core objectives:

- Increasing forest and tree cover on 5 million hectares of forest/non-forest lands.
- Improving the quality of existing forest cover on another 5 million hectares.
- Enhancing ecosystem services including carbon sequestration, biodiversity, water, and livelihood support.
- Addressing climate change through a dual approach — mitigation (reducing greenhouse gas emissions by increasing carbon sinks via forests) and adaptation (helping communities adapt to climate impacts through resilient ecosystems).

This dual strategy of adaptation + mitigation combined with forest restoration is the very essence of the Green India Mission, making Statement 3 the only accurate description.

Conclusion:
Since only Statement 3 correctly describes the aims of the Green India Mission, the answer is "3 only". Statements 1 and 2 describe objectives belonging to entirely different government missions under NAPCC and are not part of GIM's mandate.
