In recent years, with the increase in global carbon dioxide content, the negative impact of the greenhouse effect has become increasingly significant. Moreover, countries have gradually recognized the importance and urgency of carbon emission (CE) reduction. Under the dual-carbon background, CE transfer has received increasing attention. The study of its characteristics can help carry out CE reduction. Therefore, the study analyzes the characteristics of CE transfer, hoping to reduce carbon dioxide emissions. In addition, environmental policies and regulations have a significant impact on CE transfer. CE transfer under different environmental policies and regulations varies greatly. The relationship between environmental policies and regulations and CE transfer needs to be specifically analyzed. Therefore, a theoretical model is built based on environmental policies and regulations and CE transfer. This model is used to analyze the impact of different environmental policies and regulations on CE transfer. The measurement is tested via numerical simulation. The results show that good environmental policies and regulations can effectively reduce global CE. This study also compares and analyzes the relationship between differences in environmental policies and regulations and carbon leakage (CL). The results show that positive environmental policies and regulations can reduce CL, thus achieving the goal of carbon emission reduction. The above results show that in the context of dual carbon, appropriate environmental policies and regulations can reasonably regulate CE transfer and CL level. This can reduce the global emissions of carbon dioxide and the negative impact of the greenhouse effect on the world.
