Post-2020 emissions target may not win bipartisan support, Bill Shorten says

The opposition leader says he is committed to bipartisanship, but not at any cost, while government sources say no final figure has yet been decided

Bill Shorten has signalled Australia's post-2020 emissions reduction target may not win bipartisan support if Tony Abbott forces Australia into "the path of lowest common denominator" in Paris later this year.

The opposition leader told reporters on Tuesday bipartisanship was important on emissions reduction targets, but not at any cost.
