Education for Sustainable Development (ESD) has long been socialized by the government to be developed and implemented in education, but currently, its implementation has not been carried out optimally. ESD is education that makes students aware of their environmental life in creating a sustainable future by not sacrificing future generations. One effort to achieve the ESD goal is to introduce it to the community. ESD has three main objectives namely economic goals, ecological / environmental objectives, and social goals. Awareness in each individual needs to be built from elementary and middle school age so that it is embedded and embedded in the mind to realize the goals of ESD. This is where the concept of sustainable development (sustainable development) needs to be studied and applied to schools. The purpose of this paper is to investigate the ability to solve geometrical problems based on ESD and Sustainability Consciousness, then develop mathematical competencies that are relevant to the components of ESD geometry. The type of research used is qualitative research. The results of his study showed that 46.25% of students were able to solve geometric problems based on ESD, while 53.75% of students were still categorized as unable to solve them, and 31.25% of students had Sustainability Consciousness in the economic dimension, but for the environmental and social dimensions they did not have.
