According to the 2023 UNESCO's "Chat GPT and Artificial Intelligence in Higher Education Quick Start Guide", the main challenges and implications of ChatGPT in higher education are:

As the use of generative AI has increased, the effects of this technology on the environment have grown. The full extent of generative AI's energy consumption is not completely known yet. Obtaining clear data is a challenge as the AI industry isn’t transparent, and energy use varies wildly by model size, location, and what stage it’s in (training an AI model uses much more energy than prompting a query).
The conversation is further complicated because what data is available can sometimes be manipulated by people who are hoping to prove a certain viewpoint. Another complication is that AI is used to create energy efficiencies and in the future might significantly contribute to energy and climate innovations. How might that be factored into environmental impact?

What Uses More? > A calculator to compare the environmental footprint of digital tasks. The purpose of this app is not to pretend we know definitive measures of AI energy and water use, but to challenge our students to learn how dramatically various factors—like where you live or the type of prompt—can influence the footprint of both AI and non-AI tasks.
