Forecasting carbon dioxide emissions in APEC member countries by a new cumulative grey model

Abstract

The continuous increase of global carbon dioxide emissions has been the focus of human concern. Discrete Grey forecasting Model (DGM) is used to forecast the CO2 mission in Asia-pacific Economic Cooperation (APEC) member countries in 2020–2023 using data from 2014 to 2019 and the accuracy of the model was tested by the MAPE value. The results show that among the 17 predicted member states, carbon dioxide emissions show an upward trend in 13 countries, while only 4 countries show a downward trend. Faced with the current situation, all countries should pay more attention to the issue of carbon dioxide emissions and adjust their climate and energy policies.
