Singapore open to legal action against errant firms as haze crisis worsens. Singapore will “keep its options open” on taking legal action against errant companies as air quality in the city state significantly deteriorated this week due to choking haze stemming from Indonesian wildfires. The government is collecting data on the haze as it weighs possible action under its Transboundary Haze Pollution Act, Sustainability and Environment Minister Grace Fu told local media on Wednesday evening.
