Caja de herramientas del metano en el sector de los residuos sólidos

The document outlines a comprehensive approach to reducing methane emissions from solid waste, which accounts for approximately 20% of global anthropogenic methane emissions. It proposes a policy matrix categorized into legislative/regulatory, market-based, voluntary, and information/education approaches, mapped across the integrated solid waste management (ISWM) chain. The guide emphasizes that limiting global warming to 1.5 degrees Celsius requires the global implementation of solutions across all three categories of the ISWM chain: waste prevention/minimization, source separation/treatment of organics, and improved landfill engineering. It provides detailed case studies from Colombia, Germany, India, Italy, Peru, the Republic of Korea, and the United States to illustrate how different policy combinations are applied based on national contexts.

• The waste sector, including solid waste and wastewater, contributes roughly 20% of global anthropogenic methane emissions, which is approximately 5.4 gigatonnes of CO2 equivalent.
• Up to 80% of solid waste emissions can be mitigated using currently available technologies, with reduction opportunities surpassed only by the oil and gas sector.
• Legislative and regulatory approaches include pollution standards (technology-based or performance-based), source separation mandates, and bans on open dumps or the disposal of specific materials like biodegradable waste.
• Market-based instruments aim to internalize environmental costs via the 'polluter pays' principle, utilizing landfill taxes, 'Pay As You Throw' (PAYT) systems, subsidies for biogas/compost infrastructure, and emissions trading schemes.
• Information and education strategies support policy implementation through technical assistance, mandatory or voluntary disclosure of emissions data, environmental certifications, and public behavior change campaigns.
• Germany has significantly reduced methane emissions by banning the landfilling of untreated municipal waste since 2005 and requiring separate collection of biodegradable waste since 2015.
• The Republic of Korea utilizes a volume-based waste fee system introduced in 1995 and a weight-based fee for food waste introduced in 2014 to incentivize waste reduction.
• In the United States, the EPA regulates landfill air pollution under the Clean Air Act and manages the Greenhouse Gas Reporting Program (GHGRP), which requires landfills emitting over 25,000 metric tons of CO2e to report annually.
• India's 'Swachh Bharat' (Clean India) Mission uses a star-rating system (Swachh Survekshan) to create competition between cities to improve waste management and access central government funding.
