Q5. Explain the concept of Global Warming Potential. Compare its application across different greenhouse gases. Discuss its relevance for international climate negotiations. (10 M)
Difficulty Level: Medium
Reference: InsightsIAS
Why the question Global climate negotiations and carbon accounting increasingly depend on common scientific metrics, making Global Warming Potential crucial for comparing diverse greenhouse gases and shaping mitigation commitments. Key Demand of the question The question requires explaining the concept of Global Warming Potential, comparing its application across different greenhouse gases, and examining its relevance for international climate negotiations and climate governance. Structure of the Answer: Introduction Briefly introduce Global Warming Potential as an IPCC-developed metric used to standardise the warming impact of different greenhouse gases. Body Concept of Global Warming Potential: Briefly explain what GWP measures, its reference to CO₂, and the significance of time horizons. Application across greenhouse gases: Indicate how GWP differs for CO₂, methane, nitrous oxide, and fluorinated gases based on lifetime and radiative efficiency. Relevance for international climate negotiations: Outline how GWP underpins emission reporting, NDCs, equity debates, and market mechanisms. Conclusion Conclude by noting that while GWP enables comparability and collective action, evolving climate risks require complementary assessment approaches.
