Alberta Premier Rachel Notley says she told a federal environmental review panel on the Trans Mountain pipeline that her province is doing its bit for greenhouse gas emissions.

Notley says she told the three-member panel that Alberta's climate plan will cap oilsands emissions to 100 megatonnes and phase out coal-fired electricity by 2030.

Texas-based energy infrastructure giant Kinder Morgan is seeking federal approval to expand the existing Trans Mountain line in order to triple the capacity of diluted bitumen travelling from Alberta's oilsands to Burnaby B.C.

It would expand tanker traffic at the port about seven-fold.

Ottawa struck the review panel to further assess the environmental risks and to ensure that indigenous groups and others affected by the line have been consulted.

The project has faced heated opposition from environmentalists, politicians, and indigenous groups in B.C. worried about the environmental impacts and the dangers of spills.

The federal regulator, the National Energy Board, OK'd the project last month after two years of hearings and research, saying the ultimate benefit to Canadians outweighs the potential problems.

The three-member panel can't overrule the board's decision but its comments will be used by Prime Minister Justin Trudeau's government in making its final decision.
