Doer has been a strong and consistent supporter of the Kyoto Accord on climate change. In February 2004, his government signed an agreement with the Chicago Climate Exchange pledging Manitoba to create a trust fund to pay for projects that reduce greenhouse gas emissions. In 2007, he announced that Manitoba would pursue a plan with other provinces and states to push greenhouse gas emissions to 15% below 2005 levels by 2020. The next year, Doer legislated his province's commitment to meet its targets under the Kyoto Protocol by 2012.
