Abstract: The widespread use of coal, oil, and natural gas, as well as the massive emissions of greenhouse gases such as carbon dioxide, have caused increasingly serious environmental pollution and ecological damage. This paper focuses on the important global issues of coordinated development of carbon emissions (abbreviated as CE for convenience), energy, and sustainable growth, and improves this field by applying research methods based on fuzzy system theory. This paper adopts a research method based on fuzzy system theory for CE, energy, and sustainable growth, including fuzzy set modelling, fuzzy reasoning and decision-making, system optimisation, and control. In addition, based on fuzzy system theory, this paper analyses the evaluation indicators of CE, energy, and sustainable growth. When the energy consumption is 5000 kilowatt hours, the environmental protection index is 0.3. The success of this research contributes to achieving sustainable and coordinated development of energy and economy in a carbon emitting environment.

Keywords: fuzzy system theory; carbon emissions; sustainable growth; coordinated development; energy consumption.
