13.2.1 Low-Carbon Energy Tracking
Low-Carbon Energy Tracking and Monitoring Across the University
Universitas Sebelas Maret (UNS) monitors low-carbon energy use across the university by quantitatively measuring renewable energy production and regularly tracking clean energy use. The university records energy generated from solar panels, biodiesel, and biogas across its faculties and supporting facilities, then consolidates the data into an aggregated, university-level measurement. UNS also monitors the adoption of environmentally friendly transportation through its regular Emission-Free Day program, which encourages the use of electric vehicles and other low-emission mobility options across campus.
These initiatives support SDG 13 (Climate Action) by strengthening the university’s efforts to monitor low-carbon energy, reduce greenhouse gas emissions, and address the environmental impact of its operations. By measuring renewable energy production and encouraging low-emission transportation, UNS seeks to reduce its reliance on conventional energy sources and promote climate-conscious practices throughout the university community.
1. University-Wide Measurement of Renewable and Low-Carbon Energy Production
UNS measures renewable energy production and use across the university by recording energy generation from three main sources: solar panels, biodiesel, and biogas. UNS compiles data from identified faculties and supporting facilities and consolidates it into a university-level summary. This approach enables UNS to track its low-carbon energy contribution across multiple campus locations and provides a quantitative overview of renewable energy production across the university.
In 2025, UNS recorded 1,395,625.35 kWh of renewable energy, including 969,645.35 kWh from solar panels, 425,070.00 kWh from biodiesel, and 910.00 kWh from biogas. These figures show how different renewable energy sources contribute to campus energy management and provide a measurable basis for monitoring low-carbon energy production.
Table 1. Renewable Energy Production at UNS
No. | Renewable Energy Source | Energy Production (kWh) | Contribution |
1 | Solar Panels | 969,645.35 | 69.47% |
2 | Biodiesel | 425,070.00 | 30.45% |
3 | Biogas | 910.00 | 0.07% |
Total Renewable Energy Production | 1,395,625.35 | 100% |
The university also compares renewable energy production with its total electricity consumption of 11,639,840 kWh. Based on this calculation, renewable energy accounted for approximately 11.9% of the university’s total electricity consumption in 2025. This comparison indicates renewable energy’s contribution to the university’s overall energy needs and supports the evaluation of its progress toward cleaner energy use.

Renewable Energy Contribution | 11.9% |
2. Tracking Low-Carbon Energy Across Faculties and Supporting Facilities
UNS monitors solar energy as one of its main renewable energy sources. Solar panel installations are distributed across several faculties, including the Faculty of Mathematics and Natural Sciences (FMIPA), Faculty of Engineering, Faculty of Teacher Training and Education (FKIP), Faculty of Law, Faculty of Agriculture, Faculty of Cultural Sciences, Faculty of Social and Political Sciences, and Faculty of Economics and Business. The university also records additional installations at the UNS Hospital, UNS Library, UNS Inn, UNS Arboretum, Drinking Water Treatment System (SPAM), and Business Development Center.
In addition to solar energy, UNS records biodiesel facilities across several faculties and university facilities, including the Faculty of Cultural Sciences, Faculty of Teacher Training and Education, Faculty of Mathematics and Natural Sciences, Faculty of Medicine, Faculty of Social and Political Sciences, Faculty of Economics and Business, and Graduate School. Biodiesel is primarily used as an alternative energy source during power outages. Meanwhile, biogas is utilized at the Faculty of Animal Science’s Jatikuwung Animal Husbandry Laboratory Campus to support energy generation and cooking activities.
Through these records, UNS monitors renewable energy production from multiple faculties and supporting facilities and consolidates the information into an aggregated university-level measurement. This approach provides an overview of low-carbon energy contributions across the university, although the available facility-level records cover identified installations rather than demonstrating individual energy metering in every university building. By monitoring the distribution and contribution of renewable energy sources, UNS supports the transition toward lower-carbon campus operations and strengthens its efforts to reduce dependence on conventional energy sources. These initiatives support SDG 13 (Climate Action) by advancing climate change mitigation through monitoring and using renewable and low-carbon energy.

3. Implementation of Emission-Free Day and Monitoring of Clean Energy Use
UNS monitors clean energy use on campus through the Emission-Free Day program. The Green Campus and SDGs Subdirectorate initiated the program, which is held monthly at the Kentingan Main Campus in Surakarta, with restrictions on motorized vehicles. During the most recent Emission-Free Day in 2025, UNS recorded a growing number of electric cars and motorcycles on campus, including the conversion of two-wheeled vehicles from fossil fuel to electric.
The program provides an opportunity to observe the adoption of cleaner transportation and the use of electric vehicles within the university environment. Monitoring the presence and use of electric vehicles during these activities provides additional information on the academic community’s transition toward low-emission transportation and supports the university’s broader efforts to promote clean energy use.

4. Implementation of Emission-Free Day and Engagement with the Academic Community
During the 2025 Emission-Free Day, the academic community was encouraged to switch to more environmentally friendly transportation habits. To support mobility on campus, UNS provided campus buses and electric golf carts that day. The Kentingan campus looked livelier, with many community members walking and cycling.
During the most recent event in 2025, orderly internal traffic management supported restrictions on motorized vehicle access at several campus entrances. Pedestrian paths were filled with students, lecturers, and administrative staff. UNS also granted privately owned electric vehicles full access to the campus to support clean energy use. Electric Vehicle (EV)-based transportation in the form of electric golf carts was available to the academic community for inter-faculty mobility without exhaust emissions.
Information on the implementation and monitoring results of Emission-Free Day is published openly on the Green Campus UNS website, so stakeholders inside and outside the campus can access it. In the same week as the most recent Emission-Free Day in 2025, UNS consistently ranked 6th among the best sustainable campuses in Indonesia in the UI GreenMetric World University Rankings.
