Bill Gates backed Canadian scientist seek to remove CO2 from air


A Canadian company, backed by Bill Gates, says it has reached an important threshold in developing technology that can remove CO2 from the air.

Carbon Engineering has published a peer-reviewed study showing that they can capture carbon for under $100 a tonne.

This would be a major advance on the current price of around $600 per tonne.

The company says their immediate goal is to produce synthetic liquid fuels made from carbon and renewable energy.

Science sceptics

Technological “fixes” to the carbon emissions driving climate change have always been regarded with some suspicion by scientists.
