Euro-II (April 2000) is the emission norm for reducing

Options

A. `O_(3) and CO`
B. `NO_(2) and N_(2)O`
C. Sulfur and aromatic hydrocarbons
D. `CO_(4)` and particulate matter

Answer

**Step-by-Step Solution:**

1. **Understanding Euro-II Emission Norms:**
- Euro-II is an auto fuel policy that was implemented in India in April 2000.
- It aims to regulate and reduce vehicle emissions to improve air quality.

2. **Key Components of Euro-II:**
- The primary focus of Euro-II is to reduce the levels of harmful substances in fuels, specifically:
- Sulphur content in fuels.
- Aromatic hydrocarbons in fuels.

3. **Specific Targets for Reduction:**
- Euro-II sets specific limits for the reduction of these harmful substances:
- Sulphur content is targeted to be reduced to 150 parts per million (ppm) in petrol and diesel.
- Aromatic hydrocarbons are aimed to be reduced to 350 ppm in petrol and diesel.

4. **Long-term Goals:**
- The ultimate goal is to further reduce sulphur content to 50 ppm in the future, following the initial reduction to 150 ppm.

5. **Conclusion:**
- Therefore, the Euro-II emission norm is specifically aimed at reducing sulphur and aromatic hydrocarbons in petrol and diesel fuels.

**Final Answer:**
Euro-II (April 2000) is the emission norm for reducing sulphur and aromatic hydrocarbons in fuels.
