在哥伦比亚、巴西、阿根廷、哥斯达黎加、乌拉圭、墨西哥和秘鲁，畜牧业生产是一项非常重要的收入和农业温室气体排放来源。对具有肠道甲烷减排潜力的几种管理和技术选择进行了评估，预计它们的推广将有助于实现《巴黎协定》框架内的温室气体减排目标。然而，广泛采用有希望的缓解办法仍然有限，这就提出了设想的减排目标是否能够实现的问题。利用当地研究的结果，我们探索了目前提出的技术和管理实践的减排潜力，以减少拉丁美洲高排放国家养牛生产系统的肠道甲烷排放。然后，我们讨论了采用显著减少牛肠道甲烷排放的创新的障碍，以及在高排放国家提高国家目标所需的政策和实践的重大转变。利用最新的科学和当前的思维，我们提供了我们对包容性方法的看法，并重新设想学术、研究、商业和公共政策部门如何支持和激励提高雄心水平和实现可持续发展目标（SDG）所需的变革，同时考虑从农场到国家规模的行动。
Livestock production is a very relevant source of income and agricultural greenhouse gas (GHG) emissions in Colombia, Brazil, Argentina, Costa Rica, Uruguay, Mexico, and Peru. Several management and technological options with enteric methane mitigation potential have been evaluated and their scaling is anticipated to contribute toward achieving GHG emission reduction targets in the framework of the Paris Agreement. Yet, widespread adoption of promising mitigation options remains limited, raising questions as to whether envisaged emission reduction targets are achievable. Using findings from local studies, we explore the mitigation potentials of technologies and management practices currently proposed to mitigate enteric methane emissions from cattle production systems in the higher emitting countries of Latin America. We then discuss barriers for adopting innovations that significantly reduce cattle-based enteric methane emissions and the major shifts in policy and practice that are needed to raise national ambitions in the high emitting countries. Using the latest science and current thinking, we provide our perspective on an inclusive approach and re-imagine how the academic, research, business and public policy sectors can support and incentivize the changes needed to raise the level of ambition and achieve sustainable development goals (SDG), considering actions from the farm to the national scale.
