A one-hour blackout across iconic roads and buildings in Jakarta on June 13, 2026, reduced carbon emissions by 60.14 tons of CO2e and saved 75.18 MWh of electricity, worth Rp108.69 million. The event, organized by the DKI Jakarta Provincial Government for World Environment Day, involved turning off lights at landmarks like Monas and the Hotel Indonesia Roundabout, plus participation from offices and commercial buildings. The savings highlight how coordinated energy-saving actions can produce measurable environmental and financial benefits. The initiative is part of a recurring program under Governor's Instruction Number 14 of 2021, aiming to promote energy conservation and carbon reduction. Officials hope the effort encourages daily habits like turning off unused electronics and using efficient lighting, contributing to long-term sustainability in Jakarta.
