The environment is a global issue that must be addressed in a variety of ways, including education. Environmental topics will be included into mathematics, which is allowed to boost students' awareness of environmental concerns. This is a qualitative study conducted in a qualitative technique. The objectives of this study were to (1) describe students' mathematical abilities in solving problems related to environmental issues and (2) determine students' knowledge and responses to the environment. The research was performed on 26 students in class VIII at Villanova Catholic Middle School in Manokwari, West Papua, during the even semester of the 2020/2021 academic year. The results indicated that students were classified into four categories based on their ability to solve mathematical problems relating to environmental issues. Students who are capable of solving mathematical problems while also being environmentally conscious. Students that are capable of solving mathematical problems but have no interest in environmental issues. Students who are unable to answer mathematical tasks but are concerned about environmental issues, and students who are not able to solve mathematics problems at the same time do not care about environmental problems.
