Summary
Top1000funds.com published an analysis by Viktoras Kulionas, investment manager and senior environmental economist at Pictet Asset Management, on the environmental impact of AI. The article's framing, "Chicken, beef or vegetables," compares the footprint of AI with that of common food choices, and its visible excerpt cites the emissions and resource intensity associated with producing 50 grams of protein from beef as a reference point.

The piece is tagged to data centres, energy, big data and climate, reflecting the energy demand of computing infrastructure as a central element of the discussion. The full text is available only to subscribers of Top1000funds.com, so the specific quantitative findings on AI's energy use and emissions are not available in the material reviewed here. The article was produced as part of the FIS Stanford 2025 series.
