Community of Practice on Methane Emissions Reduction from Organic Sources in Latin America and the Caribbean (MetLAC)

MetLAC is a community of  public institutions, non-governmental organizations, private companies, and academic institutions from 10 countries in Latin America and the Caribbean (LAC), who participate in  dialogue, exchange of experiences, and capacity building activities, with the purpose of promoting and supporting the development of public policies, business models, and investment projects that contribute on reducing methane emissions from organic waste, as well as other sustainable development goals through actions such as composting, anaerobic digestion, food waste reduction, and similar initiatives.

This MetLAC Community of Practice (MetLAC CoP) was launched in October 2023 in response to the need to accelerate actions to reduce methane emissions from organic sources to achieve LAC´s climate change mitigation goals and at the same time contribute to other sustainable development goals such as improving  local environment, providing clean energy, creating green jobs, and fostering more sustainable circular economy approaches.

MetLAC is a joint initiative of the Center for Clean Air Policy (CCAP), ImplementaSur, and the LEDS LAC Regional Platform, with financial support from the Global Methane Hub (GMH), and has member organizations from Argentina, Barbados, Belize, Brazil, Chile, Colombia, Grenada, Honduras, Mexico, and Peru, along with facilitating organizations.

Why Methane?

Methane is a potent greenhouse gas that has global warming potential 86-times greater than carbon dioxide over a 20-year period.1 According to the Global Methane Assessment (2021), reducing human-caused methane emissions is one of the most cost-effective strategies to rapidly reduce the rate of warming and substantially contribute to global efforts in keeping the world below 1.5°C.

Furthermore, methane is among the most dangerous Short-Lived Climate Pollutants (SLCPs) and is responsible for 40 percent of the Earth’s warming since the Industrial Revolution—18% of human-made methane emissions come from organic waste.

Waste generation per capita will keep increasing around the world with population and rapid urbanization. As the organic fraction of waste—such as food residues, yard trimmings, paper or wood—decomposes in landfills or dumpsites, it generates large amounts of emissions that lower air quality and heavily contribute to the warming of our planet.

According to the United Nations Environment Programme (UNEP), organic waste represents, on average, 50% of the waste stream in Latin American countries. The lack of specific treatment options and recovery measures is causing consequential issues at final disposal sites, including significant methane emissions, leachate polluting subsoils and the spread of diseases by pests.

In the LAC region, there are local and regional initiatives focusing on recycling, anaerobic digestion, composting and other technologies that are relevant for cutting methane emissions, but those efforts are often disparate and not linked to national climate and development goals.
