Canada aims for light bulb phase-out

CANADA has switched on to Australia's plan to ban incandescent light bulbs, with Ottowa announcing its own timetable to ban the sale of the inefficient bulbs by 2012.

The ban was part of a plan to cut down on emissions of greenhouse gases, Natural Resources Minister Gary Lunn said today.

Canada is the second country in the world to announce such a ban, after Australia said in February it would phase out all incandescent bulbs by 2009.

“Making the switch to more efficient lighting is one of the easiest and most effective things we can do to reduce energy use and harmful emissions,” Mr Lunn told a news conference today.

If households installed compact fluorescent bulbs - which use about 75 per cent less electricity than old-style bulbs - they could save C$50 ($53) a year, he said.

“By banning inefficient lighting, we can reduce our greenhouse gas emissions by more than six million tonnes per year,” Mr Lunn said.

The ban will not apply to uses where incandescent bulbs are still the only practical alternative.

Today's federal announcement follows last week's pledge by the Canadian province of Ontario to ban incandescent bulbs by 2012.
