A report from a tribunal appointed by the Saskatchewan Party government says a proposed federal emissions cap and methane regulations would cause severe economic damage.

The tribunal report, struck by Justice Minister Bronwyn Eyre, says the mandates would reduce oil and gas production and cause government revenue losses of $43 billion by 2050.

It also says up to 34,000 people would lose their jobs by that year.

The federal draft regulations have proposed a ceiling on oil and gas emissions to slow the effects of climate change.
