Does democracy help reduce environmental degradation?

Area of Science:

• Environmental Science
• Political Science
• Economics

Background:

• The relationship between political systems and environmental quality is complex.
• Economic development and energy consumption patterns significantly influence environmental degradation.
• Organization for Economic Cooperation and Development (OECD) countries offer a relevant case study due to their developed economies and environmental policies.

Purpose of the Study:

• To investigate the nexus between democracy and environmental degradation in 26 OECD countries.
• To analyze the impact of energy consumption (renewable and non-renewable), income, and urbanization on environmental quality.
• To assess the implications for Sustainable Development Goals (SDGs) within OECD nations.

Main Methods:

• Panel data estimation methods were employed to account for cross-sectional dependence.
• The Augmented Mean Group (AMG) estimator was utilized for robust long-term coefficient estimation.
• Data spanned from 1990 to 2015 for 26 OECD member countries.

Main Results:

• Cross-sectional dependence and heterogeneous slope coefficients were confirmed among the panel data.
• Democracy, non-renewable energy consumption, and real income per capita were found to negatively affect environmental quality.
• Renewable energy consumption showed a positive impact on environmental quality; urbanization had no significant effect.

Conclusions:

• The study indicates that democratic governance in OECD countries may not effectively address environmental degradation.
• Achieving environmental quality targets may conflict with institutional strength and economic growth objectives outlined in the SDGs.
• Promoting renewable energy consumption is a viable strategy to mitigate environmental degradation and align with SDG environmental goals.
