As a green campus, UNS has a strong commitment to maintain and support the achievement of sustainable environment. This commitment has been realized since the founding of the campus. This commitment is then strengthened by the campus’ active participations in the ranking programme of the University of Indonesia Green Metric (UIGM) since 2013. In addition, UNS also supports the achievement of the Sustainable Development Goals (SDGs) targets by 2030. The UNS academic community plays an active role in supporting local governments or the central government to achieve the SDGs targets. In addition to supporting government policies, UNS also realizes that the challenges are increasing along with the increase of students and their motorized vehicles, which have consequences in the increasing of waste and carbon emission volumes in campus and surrounding area. A number of Rector policies have been introduced to reduce plastic uses and waste and to prohibit motorized vehicles from entering campus on certain days. Although UNS' policy after participating in the UIGM ranking is not much different from its previous policies, their policies have become more focused slowly afterwards. The policy to support green campus realisation is based on the UNS Green Campus strategic plan document. According to the UIGM, there are six aspects that must be considered as the focus of campus management, which are infrastructure, energy and climate change, solid waste, transportation, water, and education. Infrastructure policy is directed at the development of environmentally friendly facilities and infrastructure (green building) in campus area. Energy and climate change policies are directed at how the campus use renewable energy sources for their activities. The waste policy is carried out through various efforts, including reducing plastic waste, recycling waste, and conversion of waste to energy. The transportation policy is carried out by promoting walking habit, as well as using public transport (campus bus) and cycling to campus. Meanwhile, water management policies are pursued to save or make efficient the use of clean water through harvesting rainwater, managing ablution water for watering in the campus area. After all, UNS realizes that education policy is very significant for building the character of the younger generation, and therefore, courses related to the environment are continuously reproduced. No less interesting is also the campus policy to provide funding priority to research and services that engage with environmental themes.
