Risk Domain

The development and operation of AI systems causing environmental harm, such as through energy consumption of data centers, or material and carbon footprints associated with AI hardware.

"LMs (and AI more broadly) can have an environmental impact at different levels, including: (1) direct impacts from the energy used to train or operate the LM, (2) secondary impacts due to emissions from LM-based applications, (3) system-level impacts as LM-based applications influence human behaviour (e.g. increasing environmental awareness or consumption), and (4) resource impacts on precious metals and other materials required to build hardware on which the computations are run e.g. data centres, chips, or devices. Some evidence exists on (1), but (2) and (3) will likely be more significant for overall CO2 emissions, and harder to measure [96]. (4) may become more significant if LM-based applications lead to more computations being run on mobile devices, increasing overall demand, and is modulated by life-cycles of hardware."(p. 220)

"The wider environmental impact of operating LMs may be sig- nificant, however specific forecasts are missing and emissions will depend on some factors which are currently unknown [96], includ- ing (perhaps most importantly) what types of applications LMs will be integrated into, the anticipated scale and frequency of LM use, and energy cost per prompt. Ultimately, the energy require- ments and associated environmental impact of operating large-scale LMs may be anticipated to also exceed the cost of training them, especially when LMs are used more widely"
