The recovery and destruction of chlorofluorocarbons from car air conditioners became compulsory Tuesday under a new CFC recovery and destruction law.

A car owner must buy a 2,580 yen “CFC coupon” when disposing of a vehicle and taking it to either a car dealer or auto shop to pump out the CFCs, which scientists blame for depleting the Earth’s ozone layer.

The Japan Automobile Recycling Promotion Center, which issues the CFC coupons, will use the revenue to pay for recovering and destroying CFCs through government-licensed operators.
