Singapore says it is considering legal action against companies it believes are connected to sources of smoke from Indonesian forest and land fires as air quality in the city-state deteriorates to “very unhealthy” levels. Bloomberg and the South China Morning Post report that the government is collecting evidence and “keeps its options open” while monitoring the haze.

The Straits Times, as cited by the South China Morning Post, says Singapore is considering steps under its Transboundary Haze Pollution Act, a law enacted in 2014 aimed at entities that cause or condone fires where resulting haze affects Singapore. Free Malaysia Today reports that several Malaysian- and Singapore-linked firms were identified through land concessions that contain sources of smoke from the fires. Across outlets, the focus is on potential enforcement against responsible parties, though details of any specific cases or timelines are not provided.
