EF 3.1 single score: 2.19 µPt
About 3 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 | 0.03433 kg CO2 eq | 0.96 µPt | 21.06% |
| Water use | 0.0006703 m3 world eq deprived | 0.00 µPt | 8.51% |
| Resource use, fossils | 0.9583 MJ | 1.23 µPt | 8.32% |

| Claude Code, claude-opus-5-5 anthropic/claude-opus-5 · NVIDIA H100 SXM5 80GB · 276 req · 571645 in / 230363 out · batch 32 · bf16 · size inferred 78.0 B · grade E? at 0.4641 Wh per request Measured from the session transcript: 276 requests on claude-opus-5-5. Prompt tokens are those actually computed (fresh input plus cache writes); 68,903,463 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 | 128.0896 | 34.3280 | 670.293 |
Outcome. A Claude Code session, reported automatically when it ended. What it was for is deliberately not recorded here.
