Australia and Turkey have flagged they will put vehicle electrification in the fast lane at the 2026 United Nations climate summit, as the world grapples with the fallout from fuel shortages stemming from conflict in the Middle East.

Climate Change Minister Chris Bowen and his Turkish counterpart, Murat Kurum, co-hosted a ministerial meeting of 40 countries in Copenhagen on Wednesday and Thursday that will help shape the agenda of the COP31 conference in Antalya.

The annual Copenhagen talks are a pit stop on the way to the main summit and a chance to road test fresh ideas in an informal setting.

Mr Bowen and Mr Kurum nominated electrification as their big-ticket priority.

The transport sector accounts for 15 per cent of total greenhouse gas emissions, the UN says.
