Ontario's first cap-and-trade auction sells out current allowances

Ontario's first cap-and-trade auction has sold out all current allowances.

The system aimed at lowering greenhouse gas emissions requires certain electricity importers, natural gas distributors and fuel suppliers to participate.

They have caps on the amount of pollution they can emit and if they exceed those limits, they must buy an equal number credits _ or allowances _ at auction or from other companies that come in under their limits.

Results released today from the March 22 auction show that all current allowances were sold.

The government says the auction brought in $472 million

The provincial Liberal government hopes the quarterly auctions will bring in $1.9 billion a year, to be invested in programs that reduce emissions and help businesses and consumers adapt to a low-carbon economy.
