EF 3.1 single score: 0.25 µPt
About 17 seconds 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.

| Climate change | 0.003871 kg CO2 eq | 0.11 µPt | 21.06% |
| Water use | 7.559e-05 m3 world eq deprived | 0.00 µPt | 8.51% |
| Resource use, fossils | 0.1081 MJ | 0.14 µPt | 8.32% |

| Claude Code, claude-opus-5 anthropic/claude-opus-5 · NVIDIA H100 SXM5 80GB · 17 req · 99129 in / 19418 out · batch 32 · bf16 · size inferred 78.0 B · grade F? at 0.8497 Wh per request Measured from the session transcript: 17 requests on claude-opus-5. Prompt tokens are those actually computed (fresh input plus cache writes); 1,053,451 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 | 14.4451 | 3.8713 | 75.591 |
Outcome. A Claude Code session, reported automatically when it ended. What it was for is deliberately not recorded here.
