In 2023, the global consensus on carbon reduction further consolidated, and the influence of the carbon market continued to strengthen. The EU carbon price hit a record high, breaking through 100 euros/ton for the first time. The construction of China's carbon trading system has made positive progress, the national carbon emission rights trading market has generally operated smoothly, and the greenhouse gas voluntary emission reduction trading market has officially started. In the future, the scale of Chinese and foreign carbon markets will continue to expand, their role will be further enhanced, and the oil and gas industry will face both opportunities and challenges.
