EF 3.1 single score: 0.17 µPt
About 7 seconds 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).

| Claude Code, claude-opus-5-5 anthropic/claude-opus-5.5 · NVIDIA H100 SXM5 80GB · 36 req · 53673 in / 10647 out · batch 32 · bf16 · size inferred 63.6 B · grade E? at 0.3791 Wh per request Measured from the session transcript: 36 requests on claude-opus-5-5. Prompt tokens are those actually computed (fresh input plus cache writes); 2,474,948 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 | 13.6460 | 3.6571 | 71.409 |
