Impact analysis of the implementation of cleaner production for achieving the low-carbon transition for SMEs in the Inner Mongolian coal industry

• This research aimed to find effective options for reducing carbon emissions from SMEs of coal mining.
• The directions of development of enterprises for achieving low-carbon transition were investigated.
• By integrating TRIZ with the strategies of cleaner production, cleaner production measures were proposed.
• Carbon emissions from the coal mine were reduced by approximately 4% through implementing the options.

At present, carbon emissions produced by coal consumption have raised concerns around the world, but the carbon emissions associated with coal production should also be considered. As China's second-largest province for coal production, it is of extreme importance around the whole country for small and medium-sized coal enterprises in Inner Mongolia to achieve low-carbon transition.In this paper, we apply the IPAT equation to analyze the relationships among environmental impact, population, affluence and technology. The results of the analysis show that technological innovation can make an environmental impact or can cause pollutant emissions of a unit GDP to decline. Technological innovation is viewed as an avenue for environmental improvement, and corporate entities are key players in the environmental improvement. This equation can also be used indirectly on the micro-scale, for example, to determine the directions of development of enterprises and encourage the enterprises to achieve low-carbon transition as soon as possible. Selecting the example of a surface coal mine in Inner Mongolia (China) under the framework of cleaner production and the theory of inventive problem solving (TRIZ), cleaner production options helping to reduce carbon emissions were proposed and implemented. Through the implementation of the options, carbon emissions of the coal mine were reduced by approximately 4%. Contributing cleaner production options for reducing carbon emissions mainly include increasing the efficiency of energy usage, substitution of environmentally friendly materials, optimization of process controls and changing process technologies. The results obtained in this paper can not only provide a decision-making foundation for the local governments when they invest in carbon reduction projects but also play an exemplary role for other similar enterprises to reduce carbon emissions.
