| PARAMETERS | SPECIFICATIONS | ||||
India 20001 | Mukhapadhyay committee 20052 | Europe 20003 | Europe 20053 | USA RFG-34 | |
| Sulphur (per cent by weight) | 0.05 (parts of New Delhi) | 0.05 | 0.035 | 0.005 | 0.0054 |
| Aromatics (per cent by weight) | No limit | No limit | No limit | 15 | 19 |
| Polycyclic aromatic hydrocarbons (per cent by weight) | No limit | 10 | 11 | 4-1 | 2.2 |
A Note on the standards
1 The India 2000 specifications are presently in force. Similarly Europe 2000 specifications are in force across Europe.
2 The Mukhopadhyay Committee recommends the standards to be enforced from year 2005 which fall far short of the Europe 2005 specifications will come into play in 2005.
3 The RFG-3 standards are already in force in some regions of the US.The specifications are better than others proposed for future.
A Note on the parameters
1 Sulphur: An increase of even less than 1 per cent of sulphur in the fuel can increase particulate emissions drastically.
2 Aromatics and Polycyclic aromatic hydrocarbons (PAHs): PAHs are human carcinogens. Most other aromatics are toxic and can react during combustion in the engine to form Benzene, also a human carcinogen.
