Rethinking personal carbon trading (PCT) mechanism: A comprehensive review

Area of Science:

• Environmental Science
• Climate Change Policy
• Behavioral Economics

Background:

• Personal Carbon Trading (PCT) is a proposed mechanism to reduce emissions by influencing individual consumption patterns.
• Existing research often focuses on theoretical aspects and public opinion, with limited practical application and large-scale case studies.
• Understanding the link between individual behavior, consumption, and carbon emissions is crucial for effective climate change mitigation.

Purpose of the Study:

• To systematically review and analyze the existing literature on Personal Carbon Trading (PCT).
• To identify key themes, research gaps, and practical challenges in PCT implementation.
• To propose a framework for stimulating individual emission reductions through PCT.

Main Methods:

• Bibliometric analysis of 1423 research papers related to PCT.
• Identification and synthesis of key themes including carbon emissions, energy consumption, climate change, and public opinion.
• Development of a conceptual framework for PCT implementation.

Main Results:

• Key themes identified include energy consumption, climate change, and public opinion on PCT policies.
• Significant gaps exist in the quantification of carbon emissions, PCT simulation, and practical implementation.
• The concept of 'Tan Pu Hui' and large-scale case studies are underrepresented in current PCT research.

Conclusions:

• PCT has the potential to drive significant emissions reductions through consumption-based approaches and lifestyle changes.
• Further research is needed to strengthen the theoretical foundations, enhance carbon accounting, and integrate technology in PCT.
• Future efforts should focus on developing practical, large-scale PCT schemes and reinforcing integrated policy practices for effective climate action.
