%X With the development of China's economy, more and more energy consumption has led to serious environmental problems. Faced with the enormous pressure of large amounts of carbon dioxide ( CO2) emissions, China is now actively implementing the development strategy of low-carbon and emission reduction. Through the analysis of the influencing factors of CO2 emissions in China, five key influencing factors are selected: urbanization level, gross domestic product (GDP) of secondary industry, thermal power generation, real GDP per capital and energy consumption per unit of GDP. This paper applies the Elman neural network optimized by the Firefly Algorithm (FA) to forecast the CO2 emissions in China. And the results show that the performance of the FA¨CElman is better than the Elman neural network and Back Propagation Neural Network (BPNN), verifying the effectiveness of the FA¨CElman model for the CO2 emissions prediction. Finally, we make some suggestions for low-carbon and emission reduction in China by analysing key influencing factors and forecasting CO2 emissions using the FA¨CElman model from 2017 to 2020
