Research on Forecast of Carbon Emissions in China Based on WTD-PPAR Model
Carbon emission forecasting can play an effective role in promoting carbon emission planning and policy promulgation in our coun-try.The wavelet threshold denoising model can remove the noise in carbon emission data,and obtain the effective growth trend of the data.On this basis,the Projection Pursuit Autoregressive(PPAR)model is established by using the time series characteristics of carbon emission da-ta,so as to predict and analyze carbon emission.Compared with the PPAR model without denoising,BP,LSSVM,SVR and LSTM models,the WTD-PPAR model has higher prediction accuracy and more accurate prediction results.The results show that China's carbon emission will reach the peak in 2029,about 1 081.89mt,which can achieve the goal of carbon peak.
