China has recently put forth an ambitious plan to achieve carbon peak around 2030 and carbon neutrality around 2060. However, there are quite a few differences regarding the public views about China's carbon policy between the Chinese people and the people from other countries, especially concerning the doubt of foreign people about the fidelity of China's carbon policy goals. Based on Twitter data related to China's carbon policy topics from 2008 to 2020, this study shows the inter- and intra-annual trends in the count of tweets about China's carbon policy, conducts sentiment analysis, extracts top frequency words from different attitudes, and analyzes the impact of China's official Twitter accounts on the global view of China's carbon policy. Our results show: (1) the global attention to China's carbon policy gradually rises and occasionally rises suddenly due to important carbon events; (2) the proportion of Twitter users with negative sentiment about China's carbon policy has increased rapidly and has exceeded the proportion of Twitter users with positive sentiment since 2019; (3) people in developing countries hold more positive or neutral attitudes towards China's carbon policy, while developed countries hold more negative attitudes; (4) China's official Twitter accounts serve to improve the global views on China's carbon policy. |
