National Anti-Environmental Crime Task Force spotters pull over a passenger jeepney for an emission test during its Anti-Smoke Belching Operation at the corner of Commonwealth and University avenues Thursday. The Task Force, an inter-agency group consisting of the Metropolitan Manila Development Authority (MMDA), Department of Environment and Natural Resources (DENR), and the Land Transportation Office (LTO), aims to take out polluting vehicles from the Metro’s streets by pulling over a vehicle producing black smoke and placing an opacity smoke meter in its exhaust pipe.
