Abstract: The scientific community has reached a high consensus on the issue of global climate change, and human activities are the “culprit”. As a responsible major country, China has made a solemn commitment to the world to achieve carbon peak by 2030 and carbon neutrality by 2060, demonstrating its determination and confidence to lead high-quality development with green and low-carbon policies. Heat treatment is the fundamental process in the mechanical industry and a key energy consuming process in mechanical manufacturing. It is facing unprecedented pressure for energy conservation and emission reduction and has also ushered in the best window of innovation and transformation. On the basis of carbon emission accounting in the heat treatment industry, the green development process of the heat treatment industry from five aspects: green policy guidance, green standard system, green technology system, green management system and green manufacturing system were analyzed. Finally, it looks forward to the green and low-carbon development path of China's heat treatment industry under the dual carbon strategy goal.

Key words: heat treatment, dual carbon, green development, path
