UPSC CSE Context

Why in News

UNEP's 'Limiting Overshoot' report highlights that breaching 1.5°C warming is likely, urging urgent methane action and an 'overshoot, peak and decline' pathway.

Syllabus Connection

Environment and Ecology: Climate change, international agreements, and India's climate diplomacy.

Exam Relevance

Important for UPSC CSE Mains GS Paper 3 (Environment) and Essay, as it tests understanding of climate science, equity, and India's evolving role.

Core Issue

UNEP report warns 1.5°C breach likely; India faces pressure on methane and climate responsibility.

Key Development

UNEP's report emphasizes methane reduction and the 'overshoot, peak and decline' pathway, while India's exclusion from the Global Methane Pledge draws attention.

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, making its reduction critical for near-term cooling.

Exam Linkage

• Useful for questions on climate negotiations, equity, and India's stance on emission reduction commitments.

Concepts in Context

• Overshoot pathways involve temporarily exceeding a temperature target before returning below it, requiring net-negative emissions later.
• Global Methane Pledge is a voluntary commitment to cut methane emissions by 30% by 2030, which India has not joined.

Institutions and Mechanisms

• UNEP publishes Emissions Gap and Adaptation Gap reports that inform global climate policy.
• COP31 in Türkiye will be the next major climate negotiation forum.

Dynamic Analysis

International Relations

• India's stance may isolate it in climate diplomacy, as even developing countries expect major emitters to act.
• The report's focus on methane could shift negotiation dynamics, forcing India to address non-CO2 gases.

Economy

• Methane reduction in agriculture and waste sectors could impose costs on India's rural economy.
• India's reliance on coal and livestock makes methane cuts challenging without significant technological and financial support.
• The report's silence on adaptation finance undermines India's demand for support to cope with climate impacts.

Governance

• India's climate messaging needs recalibration to acknowledge its growing emissions while asserting equity.
• Domestic policies on methane, such as in waste management and agriculture, remain underdeveloped.
• The Bhotekoshi disaster highlights transboundary climate risks requiring regional cooperation.

Ethics

• India's per capita emissions are low, but its absolute emissions are high, raising questions of responsibility.
• The principle of common but differentiated responsibilities is challenged by the need for all major emitters to act.
• Ignoring the 1.5°C reality may be ethically untenable given impacts on vulnerable populations.

Prelims Takeaways

• COP31 is scheduled to be held in Türkiye in November.

Mains Value Addition

Arguments

• India must balance its development needs with growing international expectations to curb methane emissions.
• India's victim narrative is increasingly untenable as its absolute emissions rank among the highest globally.

Data Points

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

Counterpoints

• India's per capita emissions remain below world average, supporting its equity argument.
• The report lacks emphasis on adaptation finance, a key demand of developing countries.
• Methane reduction in agriculture could threaten food security and livelihoods in India.

Way Forward

• India should consider joining the Global Methane Pledge with safeguards for agricultural livelihoods.
• Enhance domestic methane mitigation in waste management, coal mining, and livestock through technology and incentives.
• Advocate for dedicated adaptation finance and technology transfer at COP31.
• Strengthen regional cooperation on climate-induced disasters, especially with Himalayan neighbors.
• Recalibrate climate diplomacy to acknowledge India's growing emissions while emphasizing historical responsibility of developed nations.
