Conteúdo:	Manual static chamber is one of the most widespread methods for the quantification of greenhouse gases (GHGs) emission from agricultural systems. But there are concerns about the reliability of measurements and a necessity to assess the static chambers used in the studies performed in the countries of Latin America. Thus, this study aims to investigate the quality of static chambers used for GHGs measurement in scientific articles following international recommendations and assess the confidence level of static chambers. A systematic review of databases was conducted to identify peer-reviewed articles that used the static chamber method in Latin América. A total of 90 articles were analyzed and separated according to the publication year (2000- 2008, 2009-2015, 2016-2020). This time interval was selected to assess the influence of key publications with guidelines and criteria for the method published in 2008 and 2015. Six design and deployment chamber characteristics were evaluated. The chambers received a global score for a confidence level according to their characteristics scores and the weight of each one. The percentage of articles with high confidence level increased within the time, and the number of articles with low confidence level reduced. Researchers should continue to follow the Global Research Alliance protocols, especially the most updated ones.
