What is the proposed carbon debt system for climate accountability?

The carbon debt system assesses each nation's consumption of its fair share of the global carbon budget, designating countries that have emitted beyond their allocation as 'carbon debtors.'

Why is exceeding 1.5°C warming significant?

Exceeding 1.5°C warming signifies a failure to prevent dangerous human interference with the climate system, a primary target under the Paris Agreement.

What remedial measures are proposed for climate overshoot?

Remedial measures include deploying CO2 removal technologies, achieving net-negative emissions, and providing support for adaptation needs and loss and damage to affected communities.

Carbon Debt: Nations Face New Climate Accountability

Summary

Scientists propose a carbon debt system for nations exceeding fair share.
Exceeding 1.5°C warming signifies dangerous human interference with climate.
Remedial measures include CO2 removal and adaptation support for harmed communities.

Carbon Debt: Nations Face New Climate Accountability

As global temperatures approach the critical 1.5°C threshold, scientists are advocating for a new accountability framework based on a 'carbon debt' system. This approach evaluates each country's consumption of its fair share of the global carbon budget, established to remain below this limit.

Nations that have emitted more than their allocated budget will be classified as carbon debtors. Subsequent emissions will accrue further debt, with future projections identifying potential future debt accumulation. This system aims to quantify responsibility for exceeding the 1.5°C limit before it is irrevocably breached.

This mechanism aligns with calls for developed nations to reduce emissions faster and invest in negative emission technologies. Remedial measures proposed include deploying CO2 removal technologies and providing support for adaptation needs and loss and damage to vulnerable communities.
