UPSC CSE Context

Why in News

UNEP's 'Limiting Overshoot' report highlights that breaching 1.5°C warming is likely, urging urgent action on methane and overshoot pathways.

Syllabus Connection

Environment and Ecology; Climate Change; International Relations; Governance.

Exam Relevance

Important for UPSC CSE Mains GS Paper 3 (Environment) and GS Paper 2 (International Relations) on climate negotiations, equity, and India's stance.

Core Issue

UNEP report warns 1.5°C breach likely, stresses methane cuts and overshoot management.

Key Development

UNEP's report emphasizes near-term methane reduction and 'overshoot, peak and decline' pathway, while India faces pressure as a major emitter.

Stakeholders

• Nepal
• Developed countries
• Global Methane Pledge signatories

Static Knowledge

High-Value Background

• The 1.5°C limit is a key goal of the Paris Agreement to avoid severe climate impacts.
• Methane has a much higher global warming potential than CO2 over a 20-year period.

Concepts in Context

• Overshoot pathways involve temporarily exceeding a temperature target before returning below it.
• Global Methane Pledge aims to cut methane emissions by 30% by 2030 from 2020 levels.

Institutions and Mechanisms

• UNEP provides scientific assessments to guide global climate policy.
• COP31 in Türkiye will be the next major climate negotiation forum.

Dynamic Analysis

International Relations

• India's non-participation in the Global Methane Pledge may strain its climate leadership claims.
• The report's focus on mitigation may widen the trust deficit between developed and developing countries on finance and technology transfer.

Environment and Ecology

• Methane reduction offers the fastest near-term cooling benefit, but India's agricultural emissions pose challenges.
• Overshoot pathways risk irreversible tipping points, making early action critical.
• The report's silence on adaptation finance undermines support for vulnerable countries facing loss and damage.

Governance

• India's climate messaging needs to balance its vulnerability narrative with its growing emissions profile.
• Domestic policies on methane, such as in agriculture and waste, require stronger implementation.
• Aligning national climate targets with global overshoot pathways demands institutional coordination.

Prelims Takeaways

• Global Methane Pledge: over 155 countries, India not a signatory.
• COP31 to be held in Türkiye in November.

Mains Value Addition

Arguments

• The overshoot pathway requires unprecedented global cooperation, yet the report lacks concrete finance mechanisms.

Data Points

• Current policies lead to 2.6°C warming; pledges lead to 1.8°C.
• Methane contributes about 0.5°C of current warming.

Counterpoints

• India's per capita emissions remain below world average, supporting its victim narrative.
• The report's emphasis on mitigation may overlook adaptation needs of developing countries.

Way Forward

• India should consider joining the Global Methane Pledge with safeguards for agricultural livelihoods.
• Advocate for dedicated adaptation finance and technology transfer at COP31.
• Strengthen domestic methane mitigation in agriculture, waste, and energy sectors.
• Calibrate diplomatic messaging to acknowledge India's growing emissions while emphasizing historical responsibility.
