# Jakarta air pollution & extreme heat 2026 > Live situation record from CLSTR: https://clstr.news/situations/jakarta-air-pollution-spikes > Updated: 2026-09-03T03:38:28.000Z. Sources: 29. Developments: 21. Jakarta’s air‑quality crisis deepened through mid‑2026. In mid‑May the city’s AQI rose to 155, prompting health warnings for children, the elderly and pregnant women. June saw a succession of unhealthy readings: AQI 117 on 5 June, 164 on 7 June, a very‑unhealthy 216‑218 on 12 June and a spike to 180 on 13 June, with PM2.5 often exceeding 70 µg/m³—far above WHO limits. The provincial government responded with a 60‑minute lights‑off on 13 June that saved 75 MWh of electricity and cut carbon emissions by 60 t CO₂e, and with free emission tests for 54 vehicles on the Kepulauan Seribu islands. A broader mitigation plan was announced, targeting 10 000 electric Trans‑Jakarta buses by 2030, expanding free public‑transport for vulnerable groups, and accelerating waste‑treatment facilities. Community engagement grew through the #SatuLangkahDulu campaign and a citizen forum on 21 June that gathered NGOs and residents to propose green‑space and waste‑management actions. A Climate Central analysis released 25 June placed Jakarta among the world’s most extreme‑humid‑heat cities, recording 210 extreme‑heat days in the 2016‑2025 period and highlighting heightened dehydration and cardiovascular risks. Pollution levels remained critical through late August. On 27 August, IQAir reported an AQI of 159 by midday, with PM2.5 concentrations at 64 µg/m³—approximately 12.8 times the WHO annual guidelines. Earlier that morning, the index was 132. In response to the ongoing crisis, the Jakarta Regional House of Representatives (DPRD DKI Jakarta) has included a Draft Regional Regulation (Raperda) on Air Pollution Control in its 2027 legislative program. This draft aims to replace an outdated 2005 regulation to address modern sources such as industrial activity, construction, and transboundary pollutants. Abdul Aziz, Chairman of the Bapemperda, stated the priority is to establish regulations that provide community protection. ## Timeline ### 2026-09-03: Jakarta air quality reaches unhealthy levels Jakarta's air quality has reached unhealthy levels, prompting health officials to urge mask use.
