Study predicts AI productivity gains may lead to net increase in CO₂ emissions

A study published in npj Climate Action suggests that AI-driven productivity gains are likely to increase, rather than decrease, global carbon dioxide emissions.
- Mechanism: AI acts as a "bidirectional productivity amplifier." While it improves efficiency in renewables (avoiding emissions), it also reduces the cost and increases the accessibility of fossil fuels (enabling emissions).
- Findings: Under parallel adoption scenarios, AI could cause a net annual increase in global CO₂ emissions of 0.47 to 1.8 gigatonnes (representing 1.2–4.8% of 2024 global energy-related CO₂ emissions).
- Perspective: Commentator @AndyMasley argues that if AI's main environmental impact is enabling easier fossil fuel access due to its general utility, it underscores the high economic value of spending emissions on data centers versus other sectors.
