JAKARTA - The one-hour blackout action carried out at a number of iconic and protocol roads in Jakarta managed to reduce carbon emissions by 60.14 tons of CO2e. In addition, electricity consumption also decreased by 75.18 MWh with a savings value of IDR 108.69 million.

The data is the result of the implementation of the Energy Saving and Carbon Emission Reduction Action held by the DKI Jakarta Provincial Government on Saturday evening, June 13, 2026, coinciding with the commemoration of World Environment Day.

Based on the records of PLN's Jakarta Raya Distribution Parent Unit (Disjaya), the action which took place from 20.30 to 21.30 WIB had a direct impact on the reduction in the use of electricity in the capital.

The blackout was carried out at a number of points that became the face of Jakarta, ranging from the National Monument (Monas), Hotel Indonesia Roundabout, Arjuna Wiwaha Statue, Youth Statue, General Sudirman Statue to the DKI Jakarta City Hall area. A number of office buildings and commercial buildings also participated in the movement.

Head of the DKI Jakarta Environment Service, Dudi Gardesi, said that the recorded energy savings showed that simple efforts could produce measurable environmental impacts when done together.

"The 60-minute blackout is not just a symbol. It is a reminder that simple steps taken together can have a real impact on the environment. From small habits, we can create big changes for a healthier and sustainable Jakarta," Dudi said in a statement, Monday, June 15.

According to him, the achievement of carbon emission reduction is proof that behavioral changes in energy use can make a real contribution to efforts to control climate change.

The implementation of the blackout action itself is an agenda carried out periodically by the DKI Jakarta Provincial Government. This activity refers to the Governor's Instruction Number 14 of 2021 concerning the Implementation of Light Blackout in the Framework of Energy Savings and Carbon Emission Reduction.

Dudi assessed that the success of the action was inseparable from the participation of various parties, ranging from building managers, business actors to the public who voluntarily turned off lights and electronic devices that were not used during the activity.

"This success was born from collaboration. Starting from building managers, business actors, communities, to residents who turned off the lights and electronic devices that were not used during the action," he said.

The DKI Jakarta Provincial Government hopes that the energy-saving movement will not stop as an annual ceremonial activity. The government continues to encourage the public to implement electricity-saving habits in daily activities, both at home and at work.

Simple steps such as turning off unused electronic devices, using energy-saving lamps, and reducing unnecessary electricity consumption can be assessed to help reduce carbon emissions sustainably.

"When millions of people take the same small steps consistently, the impact will be huge for the quality of Jakarta's environment. Because maintaining a cleaner earth and air is not only the government's task, but a joint movement of all communities," he added.
