- Methane is not only warming in itself it also contributes towards formation of regional ozone (which adds to warming).
- Methane is emitted largely from coal mining, oil and gas production, municipal solid waste and wet rice fields.
- Uses – Methane from waste is a resource and there is significant scope of capturing this from municipal waste.
- Liability – Methane emissions from the wet rice cultivation is linked with the livelihood of the poor.
Discuss: Methane is the 2nd most important greenhouse gas. CH4 is more potent than CO2 because the radiative forcing produced per molecule is greater.
