Low Emission Zones in Jakarta Effectively Reduce Air Pollution by up to 30 Percent

The Jakarta Provincial Government continues to introduce concrete solutions to curb air pollution. One strategic step is the implementation of Low Emission Zones (KRE), which have proven potential to significantly reduce pollutant concentrations.

Based on the 2025 Feasibility Assessment of Low Emission Zone (LEZ) study by Breathe Jakarta, widespread and integrated implementation of KRE could reduce PM2.5 concentrations by up to 30 percent.

“Low emission zones represent one of the strategic steps we are promoting. Controlling air pollution cannot be done alone but requires cross-sectoral, cross-regional collaboration, as well as active community support,” said the Head of the Jakarta Environmental Agency, Asep Kuswanto, in his statement in Jakarta on Monday.

Asep is also optimistic that through data-based policies, phased implementation that is “inclusive and equitable”, and strong collaboration, these efforts can deliver real improvements in air quality.

“This is a form of the government’s presence in ensuring cleaner, healthier, and more sustainable air quality for Jakarta residents,” he said.

Meanwhile, discussions on low emission zones involving researchers from the University of Indonesia and international partners from C40 through the Breathe Cities programme have been incorporated into the drafting of the Governor’s Regulation. This collaboration is part of the Jakarta Provincial Government’s efforts to ensure that policies are data-based and draw on global best practices.

Breathe Jakarta City Advisor from C40, Fadhil Firdaus, explained that implementing KRE in just one Transit Oriented Development (TOD) area could reduce PM2.5 levels in that area by 8 to 11 percent and by 3 percent across the entire Jakarta region. The impact would be even greater if applied to multiple interconnected areas.

“Low emission zones encourage changes in urban mobility systems, from private vehicles to public transport and environmentally friendly vehicles. With the right interventions, significant reductions in air pollution can be observed,” he stated.

Fadhil also explained that the KRE approach is designed to be integrated with other sectors, such as waste management and green building implementation, thereby providing broader and more sustainable environmental impacts.
