Download the Haze Outlook 2022

The annual Haze Outlook report provides an assessment of the likelihood of a transboundary haze incident affecting Indonesia, Malaysia, and Singapore. The haze is a recurring air pollution problem in Southeast Asia caused by forest and land fires, posing serious health hazards and contributing significantly to climate change.

The report is produced by the Singapore Institute of International Affairs (SIIA) with information from several sources and through engagements with our many stakeholders. Our risk assessment is based on three factors: weather (projected rainfall and temperature), people (human behaviour), and policies (climate and land management directions).

Launched at the Institute’s 9th Singapore Dialogue on Sustainable World Resources on 28 June 2022, this is the fourth annual edition of the Haze Outlook. Our inaugural report was released at the 6th Singapore Dialogue on Sustainable World Resources in May 2019. The Haze Outlook 2022 report comprises not only research and analysis, but also builds on engagement with government bodies, businesses, non-governmental organisations (NGOs), and academics.

The authors are Aaron Choo, Senior Assistant Director (Special Projects and Sustainability), SIIA, Khor Yu Leng, Senior Fellow (Sustainability), SIIA, Siti Bazilah, Senior Executive (Sustainability), SIIA, and Nadirah Sharif, Research Associate, Segi Enam Advisors. The report was directed by Simon Tay, Chairman, SIIA and Associate Professor, Faculty of Law, National University of Singapore, with input from Lim Choon Leng, Director (Policy Programmes and Development), SIIA. All views expressed in the report are those of the authors, unless otherwise credited.
