"The Europeans are incurring costs to reach their 2020 reduction targets. The Americans are incurring costs to meet their 2020 target and are on a path to achieve it," Jaccard told CBC News.
"Canada, by our own Auditor General, is not on a path to reach the 2020 target and the key reason is the oilsands."
The EU has singled out heavy crude from the oilsands as the most damaging to the world's climate.
Jaccard received a formal invitation to speak at the European Parliament as the region considers a Fuel Quality Directive policy.
He will also be speaking at The Hague and at the London School of Economics.
"I'm not opposed to the use of fossil fuels. We just can't have growing carbon pollution," Jaccard told CBC News.
"Canada is kind of the gross example right now... saying two different things. They understand the science yet, on the other hand, they are working hard to enable the building of pipelines whether in British Columbia or Keystone in the States, that over the next few years will double output."

On Thursday Natural Resources Minister Joe Oliver said Canada may dispute that claim to the World Trade Organization. A day later, he softened the stance saying going to the WTO would be a last resort.
