Methane Emissions and the European Union’s 2024 Regulation

The European Union’s 2024 regulation targets methane emissions, requiring fossil fuel companies to routinely measure, report, and reduce these emissions. This regulatory action reflects global efforts to mitigate climate change by addressing methane, a highly potent greenhouse gas with a significant role in global warming.

Methane Emissions: An Overview

Nature of Methane: Methane (CH4) is a colorless, odorless gas classified as a short-lived climate pollutant because of its relatively shorter atmospheric lifespan compared to carbon dioxide (CO2).

Global Warming Potential (GWP): Methane is approximately 80 times more potent than CO2 over 20 years, making it a critical target for climate action. Over 100 years (GWP100), methane has a global warming potential of 28. Methane is responsible for nearly 30% of global warming.

Atmospheric Lifetime: Methane remains in the atmosphere for around 12 years, significantly shorter than CO2, which can persist for centuries. However, methane’s ability to trap heat is much more intense during its short lifetime.

Major Sources of Methane Emissions

Cattle Farming: Contributes about 32% of human-caused methane emissions, primarily through manure management and enteric fermentation (digestive processes in livestock).

Landfills: Account for around 20% of methane emissions, generated from the decomposition of organic waste.

Wastewater Treatment: Responsible for 8% of global methane emissions.

Rice Cultivation: Contributes around 10%, as methane is released from the anaerobic conditions in flooded paddy fields.

Industrial Processes: Significant methane emissions are also linked to fossil fuel production, including oil, gas, and coal extraction and transport.

Natural Sources of Methane Emissions

Methane is also released naturally through wetlands, permafrost, and other natural processes. These non-human sources contribute to the methane cycle but are often exacerbated by climate change.

Methane vs. CO2: A Comparative Impact

Methane’s Short-Term Impact: Methane traps 84 times more heat than CO2 over a 20-year period, making it a critical target for short-term climate action.

CO2’s Long-Term Impact: While methane is more potent in the short term, CO2 has a longer lasting warming effect due to its extended presence in the atmosphere.

Global Initiatives and Regulations

Global Methane Pledge: Launched at the UN COP26 summit in 2021, this pledge aims to reduce methane emissions by 30% by 2030. It has been signed by over 90 countries, led by the United States and the European Union. India has not yet signed the pledge, citing concerns about
agricultural emissions.

EU’s 2024 Methane Regulation: The European Union’s regulation mandates fossil fuel companies to measure, report, and reduce methane emissions, focusing on increased accountability and transparency. This regulation is seen as a crucial step in the EU’s broader climate strategy.

Conclusion

The regulation of methane emissions is a crucial part of global efforts to combat climate change. With methane’s high global warming potential and its major contribution to global warming, regulatory measures like the European Union’s 2024 law are essential in reducing emissions from key sectors. However, further global cooperation and inclusion of large emitters like India are vital for significant progress.
