I heard Gerard Kennedy of the Liberals say that Dr. Suzuki favoured a carbon tax over cap and trade.

I wonder what the advantages of carbon tax are to make him prefer that option.

The key factor that has me at this point supporting cap and trade in that a carbon tax would not actually reduce CO2 until the tax reached $200 a tonne (or whatever level that make cleaning up more economic that polluting).  It seems to me most companies will just pay the tax rather that clean up.  The idea is to gradually increase the tax.  It seems to be just an excuse to do nothing.  Once the level gets high enough it would suddenly kick in and clean things up a a heck of a hurry.  I worry that politicians would always keep that level below the level needed to have any effect.  Politicians LOVE to look as they are doing something without actually doing anything.

In contrast, cap and trade forces a reduction in year one.
