Pace of transition to cleanstoves "worryingly slow"

Today's Independent on Sunday carries the headline: Home fires: The world's most lethal pollution.

The world's deadliest pollution does not come from factories billowing smoke, industries tainting water supplies or chemicals seeping into farm land. It comes from within people's own homes. Smoke from domestic fires kills nearly two million people each year and sickens millions more, according to the World Health Organisation (WHO).

Dr Nigel Bruce, consultant to the WHO, says: "The pace of transition to clean-burning stoves and fuels is worryingly slow".
