We’re in Delhi, looking at the impact of extreme pollution levels on workers and businesses in recent weeks.

Non-essential trucks have been banned from going into the city, and offices have asked 50% of staff to work from home.

Local markets, cafes and restaurants, as well as shopping malls, have seen a 20-30% decline in foot traffic.

Meanwhile labourers, rickshaw pullers, delivery riders and other workers paid a daily wage, have no choice but to go outside to earn a living.

In neighbouring Pakistan, air pollution has also far exceeded safe levels. We hear how people in Lahore are coping.
