Economic and Time-Sensitive Issues Surrounding CCS: A Policy Analysis.

Area of Science:

• Climate Science
• Environmental Policy
• Engineering

Background:

• Global warming necessitates urgent climate change mitigation strategies.
• Carbon capture and storage (CCS) is a proposed technological solution.
• Existing policies' effectiveness in limiting temperature rise is questioned.

Purpose of the Study:

• To evaluate the feasibility and timeliness of carbon capture and storage (CCS) in global warming mitigation.
• To assess the impact of emission growth rates on CCS viability.
• To determine if current CCS technology can meet climate targets.

Main Methods:

• Analysis of current CCS technology status, including technical, financial, and regulatory challenges.
• Simulation modeling to assess CCS relevance under different annual emission growth rate scenarios (2015-2040).
• Projection of required emission reduction rates (2040-2100) based on simulated growth.

Main Results:

• CCS technology is immature, facing significant technical, infrastructural, financial, and regulatory obstacles.
• CCS relevance is negated if annual emission growth exceeds 2% between 2015-2040.
• An average annual emission growth rate of 2.5% over the last decade makes limiting growth to 2% improbable.
• Required annual emission reductions of 5.5% by 2100 are unlikely under projected growth.

Conclusions:

• Reliance on CCS for timely global warming mitigation is currently unfeasible.
• The economic and temporal constraints of CCS are incompatible with significant climate mitigation roles.
• Urgent rethinking of climate policies and strategies beyond CCS is necessary.
