Towards a unified carbon accounting landscape

Area of Science:

• Environmental Science
• Climate Change Studies
• Chemical Industry Sustainability

Background:

• Current carbon accounting methods are diverse, leading to difficulties in comparing products and systems.
• A mix of regional and life cycle-based systems results in a lack of global emissions oversight.
• Regional approaches can incentivize territorial emission reductions, potentially leading to suboptimal global solutions and inequitable climate impact distribution.

Purpose of the Study:

• To analyze the challenges and limitations of current carbon accounting systems.
• To advocate for a more unified framework for carbon accounting.
• To promote transparent and comparable accounting methodologies for industries and regions.

Main Methods:

• Analysis of existing carbon accounting methodologies.
• Identification of inconsistencies and limitations in current approaches.
• Exploration of the implications of regional versus life cycle-based accounting.

Main Results:

• The diversity of carbon accounting methods impedes comparability and global oversight.
• Regional accounting incentives can lead to the displacement of emissions rather than global reduction.
• Current systems risk exacerbating climate injustice by disproportionately affecting vulnerable regions.

Conclusions:

• A unified carbon accounting framework is essential for effective climate change mitigation.
• Transparent and comparable methodologies are crucial for achieving climate justice.
• Standardized approaches will enable better global emissions management and support a just transition.
