The NSW Young Liberals are demanding the federal government make sweeping policy changes to tackle the "extraordinary challenges presented by human induced climate change".

In a significant move that puts them at odds with Prime Minister Scott Morrison, his branch of the Young Liberals say their generation's future depends on an overhaul of government policy.

Mr Morrison has rejected calls to change the government's climate policy despite the ongoing bushfire emergency, maintaining Australia is pulling its weight in terms of lowering emissions.

But the NSW Young Liberal president Chaneg Torres said the governing body of the party's youth wing voted unanimously at its December meeting to push for new climate change policies.
