  Prominent works in the field of Natural Language Processing have long
attempted to create new innovative models by improving upon previous model
training approaches, altering model architecture, and developing more in-depth
datasets to better their performance. However, with the quickly advancing field
of NLP comes increased greenhouse gas emissions, posing concerns over the
environmental damage caused by training LLMs. Gaining a comprehensive
understanding of the various costs, particularly those pertaining to
environmental aspects, that are associated with artificial intelligence serves
as the foundational basis for ensuring safe AI models. Currently,
investigations into the CO2 emissions of AI models remain an emerging area of
research, and as such, in this paper, we evaluate the CO2 emissions of
well-known large language models, which have an especially high carbon
footprint due to their significant amount of model parameters. We argue for the
training of LLMs in a way that is responsible and sustainable by suggesting
measures for reducing carbon emissions. Furthermore, we discuss how the choice
of hardware affects CO2 emissions by contrasting the CO2 emissions during model
training for two widely used GPUs. Based on our results, we present the
benefits and drawbacks of our proposed solutions and make the argument for the
possibility of training more environmentally safe AI models without sacrificing
their robustness and performance.
