Rising Methane Emissions in India: Threats and Solutions
Key Points
Rising Methane Emissions in India: Recent satellite data reveals that India's landfill methane emissions are significantly higher than previously estimated, indicating a substantial information gap for a gas that is 84 times more potent than CO₂ over a 20-year period. This matters for UPSC aspirants as it relates to GS Paper 3, focusing on environmental issues and climate change. Last Updated: 2025-12-16
Key Facts About Rising Methane Emissions
- Methane (CH₄) is a chemical compound with one carbon atom and four hydrogen atoms.
- It is the simplest alkane and a primary component of natural gas.
- Methane is odorless, colorless, and lighter than air.
- India is the world’s 3rd-largest methane emitter, releasing 31 million tonnes annually.
- Major sources include wetlands, agriculture, and landfills.
- Methane is 84 times more effective at trapping heat than CO₂ over 20 years.
- India's initiatives include Harit Dhara and BS VI Emission Norms.
- Global initiatives like the Global Methane Pledge aim for a 30% reduction by 2030.
India's Environmental Challenges and Global Commitments
India's rising methane emissions pose a significant challenge to its environmental goals, impacting climate change mitigation efforts. As the third-largest emitter globally, India's emissions contribute to global warming, necessitating urgent action. While international initiatives like the Global Methane Pledge aim to reduce emissions by 30% by 2030, India's non-participation highlights the need for domestic policy reforms and technological advancements to align with global standards.
