Climate change governance, cooperation and self-organization.

Area of Science:

• Environmental Science
• Behavioral Economics
• Game Theory

Background:

• Global warming presents a social dilemma, requiring individuals to balance future benefits against potential losses.
• Individual decisions in mitigating climate change are influenced by the perceived risk of failure.

Purpose of the Study:

• To introduce a simplified model for addressing social dilemmas in the context of global warming.
• To explore how risk perception and group dynamics influence collective action towards climate change mitigation.

Main Methods:

• Development of a theoretical model analyzing individual decision-making in social dilemmas.
• Comparison of model predictions with existing experimental findings on collective action.
• Extension of the model to explore practical conditions for global coordination.

Main Results:

• The model captures key features of experimental results concerning risk and collective action.
• Task segmentation into small to medium-sized groups enhances the perception of risk and minimizes uncertainty.
• Decentralized and polycentric sanctioning institutions can improve coordination for climate action.

Conclusions:

• Global coordination for climate change mitigation is more effective when tasks are divided among smaller groups.
• High-risk environments and minimized uncertainty in collective goals are crucial for successful cooperation.
• Decentralized sanctioning systems can bolster efforts to address global warming.
