B. Montreal protocol
C. Environment Act
D. Earth summit.

Answer

To solve the question regarding the appropriate measures to reduce overall greenhouse gas emissions, we will analyze the given options one by one.

### Step-by-Step Solution:

1. **Identify the Question**: The question asks about commitments to reduce overall greenhouse gas emissions.

2. **Evaluate the First Option - Kyoto Protocol**:
- The Kyoto Protocol was adopted in December 1997 during an international conference in Kyoto, Japan.
- It set binding obligations on industrialized countries to reduce greenhouse gas emissions to an average of 5% below 1990 levels during the commitment period of 2008 to 2012.
- **Conclusion**: This option is relevant to the question as it directly addresses greenhouse gas emissions.

3. **Evaluate the Second Option - Montreal Protocol**:
- The Montreal Protocol focuses on substances that deplete the ozone layer, not on greenhouse gases.
- It aims to phase out the production of ozone-depleting substances.
- **Conclusion**: This option is incorrect as it does not pertain to greenhouse gas emissions.

4. **Evaluate the Third Option - Environment Act**:
- The Environment Protection Act was enacted in India in 1986, primarily in response to the Bhopal Gas Tragedy.
- Its main focus is on environmental protection and regulation, rather than specifically targeting greenhouse gas emissions.
- **Conclusion**: This option is also incorrect.

5. **Evaluate the Fourth Option - Earth Summits**:
- Earth Summits are meetings organized by the United Nations to discuss sustainable development.
- While they address various environmental issues, they do not specifically commit to reducing greenhouse gas emissions.
- **Conclusion**: This option is incorrect as well.

6. **Final Conclusion**:
- After evaluating all the options, the correct answer is the **Kyoto Protocol**, as it specifically commits to reducing greenhouse gas emissions.

### Final Answer:
The appropriate measures to reduce overall greenhouse gas emissions are the commitments of the **Kyoto Protocol**.
