The Chinese city of Changzhou announced plans to build what it calls the country's first city-level 'green token factory' — a large-scale facility that will produce tokens for artificial intelligence computing using only clean energy. The project was revealed at the World Artificial Intelligence Conference in Shanghai on Sunday. Once completed, the factory is expected to generate up to 60 trillion tokens per year. Tokens are basic units of data that AI models process, and the growing demand for AI services requires enormous computing power, which often leads to high energy consumption. By powering the facility entirely with green energy, Changzhou aims to support China's national push to meet AI computing needs while reducing carbon emissions. The announcement comes as local governments across China race to build infrastructure for AI development, following Beijing's call for a balance between technological growth and environmental goals. Changzhou, in eastern China, already has a strong manufacturing base and is positioning itself as a hub for green technology. While the project is still in the planning stage, it highlights the increasing focus on sustainable AI infrastructure. The factory is expected to boost the local economy and set a model for other cities to follow. No specific timeline for completion has been provided yet.
