Built structures influence patterns of energy demand and CO₂ emissions across countries

Area of Science:

• Environmental Science
• Urban Planning
• Energy Policy

Background:

• Built structures influence energy demand and CO2 emissions at urban scales.
• National-level analysis of built structures' impact is limited by data availability.
• GDP is a primary factor in national energy and emissions assessments.

Purpose of the Study:

• To develop national-level indicators for built structure patterns.
• To assess the influence of built structures on energy use and CO2 emissions across 113 countries.
• To compare the predictive power of built structure indicators with conventional factors like GDP.

Main Methods:

• Quantification of national-level built structure indicators for 113 countries.
• Statistical analysis correlating built structure indicators with final energy use and territorial CO2 emissions.
• Inclusion of conventional determinants (e.g., GDP) in the analysis.

Main Results:

• National built structure indicators are significant predictors of energy demand and CO2 emissions.
• These indicators demonstrate comparable importance to GDP and other conventional factors.
• Area of built-up land per capita emerged as the most influential predictor, second only to GDP.

Conclusions:

• Built structure patterns are critical determinants of national energy consumption and CO2 emissions.
• Incorporating built environment indicators enhances the understanding of energy-economy-environment interactions.
• Policy implications for sustainable urban development and national emissions reduction strategies.
