Singapore is investigating ten companies regarding violations of its Transboundary Haze Pollution Act. The investigations stem from the significant haze events impacting Singapore. At least four of these firms have established connections to Asia Pulp and Paper, a large Indonesian pulp and paper company. These notices were issued as Singapore authorities seek to hold accountable those contributing to the recurring haze problem. The situation highlights ongoing concerns about cross-border pollution originating from Indonesia. The investigations aim to enforce Singapore’s haze laws and deter future irresponsible land clearing practices. This action underscores Singapore’s commitment to addressing the health and economic impacts of the haze.
