Abstract: Through the preliminary accounting of greenhouse gases generated by cement, lime, aluminum,calcium carbide and other industries involved in the industrial production process of Wenshan Prefecture in recent years, the greenhouse gas emissions generated in the industrial production process of Wenshan Prefecture were estimated. Its change trend was analyzed in combination with the industrial capacity planning. It was aimed to calculate the peak carbon in the industry of Wenshan Prefecture, which would provide scientific reference for the local government to formulate countermeasures of lowering the carbon emission and achieve the goal of decreasing the carbon-intensive.
