Eco-Efficiency Ranking & Paradox
GPT-4o Annual Environmental Impact

Our framework analyzed over 30 state-of-the-art LLM models, quantifying their energy, water, and carbon footprints across various deployment scenarios. This provides an unprecedented level of granularity for sustainability assessment.

Our novel methodology integrates real-time performance data with infrastructure-level multipliers (PUE, WUE, CIF) and statistical analysis to accurately estimate resource consumption per-prompt. This approach bridges the gap between model performance and real-world environmental impact.

Cross-efficiency DEA reveals that eco-efficiency hinges on both model design and infrastructure. Models like Claude-3.7 Sonnet lead with high scores, while models like DeepSeek-R1, despite their intelligence, rank low due to high resource demands.

Despite per-query efficiency, the sheer scale of AI adoption, exemplified by GPT-4o's estimated annual usage, drives disproportionate resource consumption, illustrating the 'Jevons Paradox' in action.

Scaling the GPT-4o Footprint

A single short GPT-4o query consumes 0.42 Wh. Scaled to 700 million queries/day, GPT-4o's annual impact in 2025 is projected to be:

Electricity: 391,509 MWh annually (min) to 463,269 MWh annually (max), comparable to 35,000 U.S. homes.
Water: 1,334,991 kL (min) to 1,579,680 kL (max) of freshwater evaporated, equivalent to the annual drinking needs of 1.2 million people.
Carbon Emissions: 138,125 tons CO2e (min) to 163,441 tons CO2e (max), requiring a Chicago-sized forest to offset. This highlights the growing paradox of increasing AI usage despite per-query efficiency gains.
