EF 3.1 single score: 40.94 µPt
About 47 minutes of an average person's yearly footprint in these categories. 4 of 16 categories, 45% of the EF weight. Fossil resource use is estimated from all primary energy, which overstates it; water scarcity uses the aware world average (1.0); the dutch factor is not loaded.
| category | amount | score | weight |

| Climate change | 0.6406 kg CO2 eq | 17.86 µPt | 21.06% |
| Water use | 0.01251 m3 world eq deprived | 0.09 µPt | 8.51% |
| Resource use, fossils | 17.88 MJ | 22.89 µPt | 8.32% |

Prompt tokens are those actually computed (fresh input plus cache writes); 390,726,369 more were read from the prompt cache and are not recomputed, and loading that cache is not modelled. The model's size is not published, so it is inferred from its price. | assumed | 1252.6936 | 335.7219 | 6555.346 |
