In order to implement the work deployment of the CPC Central Committee and the State Council on carbon peak and carbon neutralization, resolutely curb the blind development of "two high" projects, promote the green and low-carbon transformation of key industries such as oil refining, ethylene, synthetic ammonia and calcium carbide, and ensure the realization of the carbon peak goal on schedule, this action plan is formulated in accordance with the opinions on strict energy efficiency constraints and promoting energy conservation and carbon reduction in key fields. 1、 Action goal by 2025, through the implementation of energy conservation and carbon reduction actions, the proportion of production capacity reaching the benchmark level in the oil refining, ethylene, synthetic ammonia and calcium carbide industries will exceed 30%, the overall energy efficiency level of the industry will be significantly improved, the carbon emission intensity will be significantly reduced, and the ability of green and low-carbon development will be significantly enhanced. The specific indicators of benchmark level and benchmark level are as follows.
