TORONTO - The Ontario Chamber of Commerce is urging the provincial government to delay the implementation of its cap-and-trade plan for one year.

The plan to reduce greenhouse gas emissions is set to take effect next year, but the chamber says key questions remain unanswered.

President and C-E-O Allan O'Dette says the government has not released an analysis of the economic impact of cap and trade.

He also says businesses are still seeking details on how the revenue will be invested and administered.

The enabling legislation is expected to pass soon, with a third reading debate held on it yesterday afternoon.

Under cap and trade, industries are given specific pollution limits, but can sell their emission allowances to other companies if they come in below their annual limit, or buy credits if they exceed it.
