EF 3.1 single score: 96.18 µPt

About 70 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).

Measured from the session transcript: 3053 requests on claude-opus-5-5. Prompt tokens are those actually computed (fresh input plus cache writes); 1,560,733,766 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.
