Hugging Face's model hub has started tracking carbon emissions for its users. This is done by estimating emissions from computations on their models, using data provided by the European Commission's JRC. The goal is to raise awareness about the environmental impact of AI development and usage. --- Why it matters: This matters because it highlights the often-overlooked environmental cost of training and running large language models like those used in Hugging Face's hub.
