Scientists have turned carbon dioxide back into coal in a world-first breakthrough which could lead to cleaner air.

They say the ground-breaking technique can efficiently convert CO2 from a gas into solid particles of carbon.

The research team, led by RMIT University in Australia, developed the new technique which they say offers an "alternative pathway" for safely and permanently removing the greenhouse gas from our atmosphere.

Current technology for carbon capture and storage focuses on compressing CO2 into a liquid form, transporting it to a suitable site and injecting it underground.
