EF 3.1 single score: 2.16 µPt
About 2 minutes of an average person's yearly footprint in these categories. 9 of 16 categories, 72% of the EF weight. Fossil resource use counts the fuel burnt for dutch electricity, not its supply chain; water scarcity uses the aware factor for the netherlands (0.957).

| Water use | 0.0008916 m3 world eq deprived | 0.01 µPt | 8.51% |

| Claude Code, claude-opus-5-5 anthropic/claude-opus-5.5 · NVIDIA H100 SXM5 80GB · 200 req · 432603 in / 139984 out · batch 32 · bf16 · size inferred 63.6 B · grade F? at 0.8900 Wh per request Measured from the session transcript: 200 requests on claude-opus-5-5. Prompt tokens are those actually computed (fresh input plus cache writes); 37,527,265 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 | 177.9936 | 47.7023 | 931.440 |
