Abstract
Greenhouse gas
emissions currently endanger the ecosystem by causing climate change and global
warming, as a result of the burning of coal, fossil fuels, industrial processes,
and deforestation. Therefore, tracking past, current, and future greenhouse gas
emission levels is indispensable for mitigating their adverse effects on the
global environment. The present study evaluated the 2011–2023 U.S.
Environmental Protection Agency Greenhouse Gas Reporting Program data using a
multilayered Gated Recurrent Units model, providing a deep learning approach to
forecasting non-linear, multi-year industrial emission time series. By
automatically identifying complex data patterns, the model outperformed deep
learning approaches to forecasting greenhouse gas emissions. The model showed a
high predictive accuracy (R2 of 0.940, MAE = 0.023, RMSE = 0.048),
considerably robustified by the integration of the sensitivity and uncertainty
analyses. The results indicated that the optimal model for 2028 consists of a
five-year projection plus the 2023 actual CO2e levels. The model
also confirmed that CO2e levels were on a downward trajectory,
showing a decline in projected emissions for 2028 when compared to the 2023
actual emissions of 3,757,462,133 metric tons. Implications for future study
were forwarded.
