Mitigación del Metano del Sector de los Residuos

This report by the Global Climate and Health Alliance, prepared by Abt Associates, examines the sources of methane emissions from the waste sector—specifically municipal solid waste and wastewater—and the associated public health benefits of mitigation strategies. It provides technical solutions for reducing methane and outlines a framework for international, national, and local action to improve health equity and climate resilience.

• The waste sector is responsible for 3% of total global greenhouse gas emissions and accounts for one-fifth of all anthropogenic methane emissions worldwide.
• Municipal solid waste contributes approximately 12% of global anthropogenic methane emissions, primarily through the anaerobic decomposition of organic materials like food and garden waste. Wastewater contributes approximately 8% of these emissions, stemming from the decomposition of human waste and other organic matter in sewers or storage systems.
• Reducing methane from waste can significantly lower tropospheric ozone, a toxic pollutant. According to the Global Methane Assessment, implementing waste-sector methane solutions could prevent 45,000 ozone-related deaths, 135,000 emergency room visits for asthma, 5 metric tons of crop losses, and 13 billion work hours annually.
• Poor waste management leads to severe physical and health risks. For example, non-compacted landfills increase the risk of landslides; in 2017, a garbage slide in Addis Ababa, Ethiopia, killed 116 people. Additionally, inadequate wastewater infrastructure contributes to waterborne diseases, with the CDC estimating that lack of hygiene and drinking water contributed to 829,000 deaths globally in 2016.
• Nigeria's 2018 National Action Plan to Reduce Short-Lived Climate Pollutants aims to recover 50% of landfill methane and reduce methane from open waste burning by 50% by 2030. Full implementation of 22 priority measures is estimated to reduce national methane emissions by 61% and prevent 7,000 premature deaths from air pollution by 2030.
• Indonesia is the world's largest emitter of wastewater methane. The report notes that 31% of the rural population uses pit latrines as the primary wastewater treatment source. Implementing anaerobic treatment with gas collection could reduce wastewater greenhouse gas emissions by 52% to 87% compared to current levels.
• India faces significant wastewater challenges, with all its treatment plants combined only capable of treating 37% of the country's generated wastewater. As of 2010, 50% of the country (652 million people) relied on open defecation, the highest per capita rate in the world.
• The Philippines' 2019 National Strategy to Reduce Short-Lived Climate Pollutants targets having 50% of landfills equipped with greenhouse gas capture systems and diverting 24% of organic waste to composting by 2030 (relative to 2010 levels).
