Ontario Announces Results of September Cap and Trade Program Auction

Proceeds Helping Households and Businesses Fight Climate Change

Today, Ontario announced the results of the province's third auction of greenhouse gas emission allowances, held Sept. 6, 2017.

A total of 25,296,367 current (2017) allowances were sold at a settlement price of $18.56 CAD and a total of 3,116,700 future (2020) greenhouse gas emission allowances were sold at a settlement price of $18.03 CAD. The auction generated an estimated $525,694,672 CAD in proceeds, which by law will be invested in programs that will reduce greenhouse gas pollution and help families and businesses reduce their own emissions through the Climate Change Action Plan.

Proceeds from the province's carbon market auctions are funding programs in 2017-18 that help people and businesses across Ontario reduce pollution, including:

These recent investments build upon $50 million for cycling upgrades, $200 million for public school energy improvements, $100 million to help homeowners make home energy upgrades, $20 million to install a network of fast-charging electric vehicle stations, $92 million for social housing upgrades, nearly $100 million to help businesses adopt low-carbon technology, and $13 million to support clean economic growth in First Nations communities.

The auction was administered using services contracted by the Western Climate Initiative (WCI) Inc., with oversight from an independent market monitor to ensure market integrity.

The summary report of the results has been made available to the public.

Quick Facts

  • On May 18, 2016, Ontario passed landmark climate change legislation that ensures the province is accountable for responsibly and transparently investing proceeds from the cap and trade program.
  • The Climate Change Action Plan and the cap and trade program form the backbone of Ontario's strategy to cut greenhouse gas pollution to 15 per cent below 1990 levels by 2020.
  • In April 2015, Ontario announced its intention to join the linked system under the Western Climate Initiative, partnering with other jurisdictions, including Quebec and California, and making carbon pricing a cornerstone in Ontario's fight against climate change.
  • After introducing its cap and trade program and putting a price on carbon, California’s economy grew at a pace that exceeded the growth of the rest of the U.S. economy.
  • The number of jobs in California grew by almost 3.3 per cent in the first year and a half of the program, outstripping the national rate of job creation, which was 2.5 per cent over the same period.
  • In the United States, the Regional Greenhouse Gas Initiative (RGGI) has invested more than $1.3 billion of auction proceeds since 2009 in programs that include energy efficiency, clean and renewable energy, greenhouse gas abatement and direct bill assistance.
  • RGGI investments are projected to return more than $4.67 billion in lifetime energy bill savings to more than 4.6 million participating households and 21,400 businesses.

“The goal of Ontario’s carbon market is to reduce greenhouse gas emissions from our largest sources of pollution. The proceeds generated are being invested into Ontario’s economy through programs and projects that will do even more to reduce greenhouse gases, and help people in their everyday lives.”
