Central Idea

• At the COP28 climate talks in Dubai, discussions have centered on carbon capture and storage (CCS) and carbon-dioxide removal (CDR) technologies.
• The interpretation of ‘abatement’ is crucial in understanding the role and limitations of CCS and CDR in climate action.

Understanding CCS and CDR

• CCS: This involves capturing CO₂ emissions at their source, such as in the fossil fuel industry and industrial processes, and storing them to prevent atmospheric release.
• CDR: Encompasses natural methods like afforestation and technological approaches like direct air capture for absorbing and storing atmospheric CO₂.
• COP28 Discussions: The term “unabated fossil fuels” in the draft texts refers to fossil fuel combustion without CCS. The texts advocate phasing out such fuels and enhancing emission removal technologies.

Scale and Efficacy of CCS and CDR

• IPCC’s AR6 Report: Heavily reliant on CDR for meeting the 1.5 degrees C temperature limit, assuming significant CO₂ sequestration by 2040.
• Challenges: Direct mitigation to reduce emissions is daunting, making CDR crucial.
• CCS Limitations: Effective CCS requires high capture rates, permanent storage, and minimal methane leakage from upstream processes.

Concerns and Implications of CCS and CDR

• Land Use for CDR: Large-scale CDR methods, especially technological ones, require significant land, raising equity, biodiversity, and food security concerns.
• Impact on the Global South: CDR projects in the Global South could infringe on indigenous land rights and compete with agricultural land use.
• Financial and Ethical Questions: The cost and responsibility of implementing CDR at scale raise questions about who should bear these burdens.

Pitfalls of CCS and CDR

• Potential for Increased Emissions: CCS and CDR could inadvertently create leeway for continued or increased greenhouse gas emissions.
• IPCC Emission Scenarios: To limit warming to 1.5 degrees C, significant reductions in coal, oil, and gas use are required by 2050, with or without CCS.
• Gas Emissions Pathways: Higher reliance on CCS and CDR could lead to emission pathways with a greater contribution from gas.

Conclusion

• Critical Decade Ahead: The next decade is pivotal in determining the viability and scalability of CDR methods.
• Balancing Act: While CCS and CDR offer potential solutions for emission reduction, their implementation must be carefully managed to avoid unintended consequences and ensure equitable and effective climate action.
• Future of Climate Negotiations: The discussions and decisions at COP28 regarding CCS and CDR will significantly influence the trajectory of global climate action and the pursuit of the 1.5 degrees C target.

Central Idea

• The Dubai Consensus, a significant resolution towards reducing fossil fuel dependency, was adopted in COP 28, Dubai.

Dubai Consensus

• Key Clause: The resolution emphasizes transitioning away from fossil fuels to achieve net-zero emissions by 2050, aligning with scientific recommendations to limit global temperature rise.
• Balance between Countries: The text reflects a compromise between developed and developing nations on climate action and responsibility.
• Dilution of Language: Earlier drafts with terms like ‘phase-out’ were softened due to opposition from oil-dependent countries.
• Coal Usage: The final text moderated its stance on coal, crucial for countries like India, calling for a phase-down rather than a rapid phase-out.
• Methane Emissions: The consensus introduces a focus on reducing methane emissions by 2030, a potent greenhouse gas.
• Natural Gas as a ‘Transition Fuel’: The text’s reference to natural gas as a transitional fuel could favor gas-producing countries and overlook the need for developed countries to close the finance gap in climate adaptation.

New Funding Commitments and Future Goals

• Diverse Opinions: While some nations expressed dissatisfaction with the agreement’s scope, others highlighted the lack of financial support for developing countries.
• Financial Pledges: COP 28 saw commitments to the Loss and Damage Fund and pledges to decarbonize the global economy.
• Focus on Renewable Energy: The resolution signals a move towards phasing out fossil fuels and boosting renewable energy and efficiency.

India’s Historical Position on Climate Change

• Emission Statistics: India, a major developing country, has historically contributed 3% of greenhouse gases (1850-2019), compared to higher percentages from the US and EU.
• Per Capita Emissions: India’s per capita emissions are below the global average, but its development needs and population growth have made it the third-largest emitter.
• Balancing Development and Emissions: India has been navigating the pressure to reduce emissions while addressing its developmental needs, particularly its reliance on coal.

India’s Commitments and Challenges

• Net Zero by 2070: India has committed to achieving a net-zero state by 2070, alongside expanding its renewable energy capacity.
• Glasgow COP 2021 Agreement: Under pressure, India agreed to a ‘phase-down’ of coal use, highlighting the need for equitable treatment of all fossil fuels, including oil and gas.
• Import Dependency: As a net importer of oil and gas, India has raised concerns about the focus on coal while other fossil fuels remain under-addressed.
