Since food is a necessity for human life, there have been many innovations aimed at speeding up food production. However, these innovations can have negative effects on the environment and, thus, the overall food system. Greenpeace, a non-governmental organization, creates food campaigns that include online materials touting a better food system, naming bad corporations, and asking readers or supporters to join the campaigns. This study analyzes Greenpeace’s attitude in evaluating the environment using Halliday and Matthiessen’s transitivity system and Martin and White’s appraisal framework. The research was conducted using UAM CorpusTool software to perform a quantitative analysis of the data in terms of transitivity and appraisal. The results show that Greenpeace’s food campaigns contain judgments as the most frequent appraisal in material clauses and relational clauses. These judgments concern how entities, processes, and innovations affect the environment.
