| Pollutant | Coal | Oil | Natural Gas | Nuclear |
|---|---|---|---|---|
| SO₂ (tonnes/yr) | 700 | 700 | ~0 | ~0 |
| NOₓ (tonnes/yr) | 700 | 700 | 200 | ~0 |
| CO₂ (tonnes/yr) | 230,000 | 180,000 | 100,000 | ~0 |
Note: The CO₂ figure for nuclear refers to direct operational emissions only. Full life-cycle analyses (including construction, mining, and decommissioning) give nuclear a small but non-zero carbon footprint, still far lower than any fossil fuel.
