The table below shows the mass of various pollutants emitted by a car using conventional diesel compared to one using biodiesel.
| Pollutant | Mass of pollutant emitted in g per km driven | |
|---|---|---|
| Conventional Diesel | Biodiesel | |
| Carbon dioxide (net) | 165 | 42 |
| Carbon monoxide | 0.14 | 0.09 |
| Nitrogen oxides | 1.1 | 1.4 |
| Particulates | 0.022 | 0.028 |
| Sulfur dioxide | 0.0048 | 0.0008 |
Explain, using information from the table, one way in which the biodiesel engine is less damaging to the environment than the conventional diesel engine.
