• The Climate & Clean Air Coalition announced USD 500,000 in funding will support cities participating in Lowering Organic Waste Methane (LOW-M) to implement targeted actions that reduce methane emissions from the waste sector. These efforts will focus on strengthening financial mechanisms, data systems, and policy and regulatory frameworks.
• The Government of Brazil announced an investment of BRL 2 billion (approximately USD 370 million) to advance national initiatives in waste management and the circular economy.
• Global Methane Hub committed USD 10 million to establish a Latin America and the Caribbean regional program. The investment will support municipalities in developing and implementing city-level methane reduction strategies, mobilizing data, finance, and policy innovation to deliver measurable progress in the years ahead.
• The city of Salvador, Brazil, announced its accession to the LOW-M initiative and reaffirmed its commitment to reducing methane emissions from waste. Salvador has already achieved significant climate benefits through biogas capture from landfills. By joining LOW-M, the city aims to strengthen its integrated approach that links climate action with broader social and environmental co-benefits.
