# South American climate and sustainability initiatives > Live situation record from CLSTR: https://clstr.news/situations/south-american-climate-and-sustainability-initiatives > Updated: 2026-08-19T13:30:01.000Z. Sources: 5. Developments: 2. Climate mitigation and sustainability initiatives are expanding across Argentina and Chile, focusing on livestock management and maritime decarbonization. In Argentina, efforts have moved from local economic diversification through thermal projects in Tolhuin to broader environmental conservation. The Nature Conservancy launched the Patagonia Technical Support Platform (PAT Pat) to promote regenerative livestock systems in Northern Patagonia, aiming to conserve steppe ecosystems and mitigate climate change through inter-institutional cooperation. In Chile, scientific research has targeted methane reduction in the livestock sector by using seaweed in bovine diets, which demonstrated no negative impact on milk production. This focus on environmental innovation has expanded to include maritime sectors, where authorities and researchers in Puerto Montt are developing a roadmap for maritime decarbonization and exploring methods to address ocean acidification. ## Timeline ### 2026-08-19: South American climate initiatives focus on livestock and maritime decarbonization Climate mitigation initiatives are advancing in South America, with new sustainable livestock platforms in Argentina and a maritime decarbonization roadmap being developed in Chile. 3 sources. https://clstr.news/cluster/south-american-climate-initiatives-focus-on-livestock-and-maritime-decarbonization ### 2026-08-15: Tolhuin advances thermal project as Chilean study reduces methane Tolhuin, Argentina, moves forward with a thermal complex project to boost tourism, while Chilean researchers successfully use seaweed in cattle diets to reduce methane emissions. 2 sources. https://clstr.news/cluster/tolhuin-advances-thermal-project-as-chilean-study-reduces-methane --- Cite as: South American climate and sustainability initiatives.
