EF 3.1 single score: 50.85 µPt
About 59 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 | 0.7957 kg CO2 eq | 22.19 µPt | 21.06% |
| Water use | 0.01554 m3 world eq deprived | 0.12 µPt | 8.51% |
| Resource use, fossils | 22.21 MJ | 28.43 µPt | 8.32% |

Prompt tokens are those actually computed (fresh input plus cache writes); 1,046,730,316 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 | 2796.9214 | 749.5749 | 14636.290 |
| Claude Code, claude-opus-5-5 anthropic/claude-opus-5 · NVIDIA H100 SXM5 80GB · 352 req · 1220870 in / 223910 out · batch 32 · bf16 · size inferred 78.0 B · grade E? at 0.4890 Wh per request Measured from the session transcript: 352 requests on claude-opus-5-5. Prompt tokens are those actually computed (fresh input plus cache writes); 114,299,081 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. anthropic/claude-opus-5.5 is not in the registry yet, so the size of anthropic/claude-opus-5 is used. | assumed | 172.1407 | 46.1337 | 900.812 |
