Emissions of carbon dioxide (CO2) result from burning fossil fuels. Industrial activities continue to produce CO2, which can increase by up to 64% annually. CO2 raises global temperatures; this has adverse effects on the climate, leading to climate change. In Indonesia, 56% of electricity is generated using coal-fired power plants, a process that significantly contributes to CO2 emissions through coal combustion. Consequently, optimising electricity usage is paramount to mitigating these emissions effectively. Reducing emissions is one way to address climate change. Therefore, this study aims to ascertain how university students implement and respond to project-based electricity saving. This case study involved 75 participants enrolled in the Statistics Department. The findings demonstrated that students could complete the one-month project electricity saving (kWh), resulting in reductions in emissions of CO2 (kg) and developing as sense of Quantitative Literacy (QL). The most popular ways to save electricity are to turn off lights and televisions, unplug phone chargers, use LED lighting, and control the use of electrical fans. From this study, it can be inferred that students were capable of finishing the project with a satisfactory rating of 4.5/5. The students in this study are expected to continue their energy-saving initiative upon the conclusion of this project. They are also encouraged to take part in more projects. Further research to determine how much longer-term energy saving can be performed by students is suggested. © 2025 Environmental Education Association of Southern Africa.
