Manitoba's booming oil patch has become the biggest greenhouse gas emitter in the province.
New data provided by the Manitoba government's petroleum branch suggest greenhouse gas emissions from the oil patch increased to 813 kilotonnes last year.
That's the same as 168,000 cars on the road for a year.
Petroleum branch spokesperson Keith Lowden says they're doing things to help the issue.
Lowden says the oil patch has become an important component in Manitoba.
The oil patch only contributes 3-4% of the province's total gas emissions.
There are over 3000 oil wells in Manitoba.
