What is Grey Prediction Models for CO2 Emissions?

Grey prediction models for CO2 emissions apply grey system theory forecasting techniques, such as GM(1,1) and multivariable grey models, to predict carbon dioxide emissions from sectors like transportation and industry using limited historical data.

These models excel in data-scarce environments common in developing regions for CO2 forecasting. Key works include Ye et al. (2020) with 128 citations on time-delay multivariate grey models for China's transportation CO2 emissions and Qader et al. (2021) with 111 citations forecasting Bahrain's power generation emissions. Over 10 papers since 2017 demonstrate hybrid grey approaches with decomposition or optimization for improved accuracy.

Key Challenges

Why It Matters

Grey prediction models enable reliable CO2 forecasting in data-limited regions, supporting climate policy evaluation and emission reduction strategies. Ye et al. (2020) analyzed transportation sector impacts in China, aiding targeted decarbonization policies. Qader et al. (2021) provided Bahrain-specific forecasts for energy planning, while Rao et al. (2023) extended STIRPAT with grey elements for Hubei Province carbon neutrality scenarios, influencing regional sustainability goals.

Key Research Challenges

Handling Time-Delay Effects

CO2 emissions from transportation exhibit delayed responses to policy changes, complicating standard grey models. Ye et al. (2020) introduced a time-delay multivariate grey model to address this, improving prediction for China's sectors. Accurate capture remains challenging with sparse data.

Multivariable Interaction Modeling

Integrating factors like FDI and energy consumption requires advanced grey models to avoid oversimplification. Jiang et al. (2020) used an improved grey multivariable Verhulst model for bilateral FDI effects on China's CO2. Balancing model complexity with data scarcity persists as a hurdle.

Scenario Analysis Integration

Forecasting under carbon neutrality scenarios demands hybrid grey extensions with regression techniques. Rao et al. (2023) combined STIRPAT with ridge regression for Hubei Province emissions. Ensuring robustness across optimistic and pessimistic paths challenges grey model reliability.
