WITH THE sharp fall in Delhi’s air quality prompting the government to put together an emergency plan for the coming week, including shutting schools and asking employees to work from home, there are some lessons to be learned from the model implemented in Singapore three years ago.

In 2013, after Singapore faced a record-breaking haze like the one that has blanketed Delhi, the country’s National Environment Agency and the ministries of education and manpower got together to formulate a set of guidelines, specifically for schools and employers, and that includes providing masks and installing air purifiers.
