A breakthrough in the race to make useful products out of planet-heating CO2 emissions has been made in southern India.
A plant at the industrial port of Tuticorin is capturing CO2 from its own coal-powered boiler and using it to make baking soda.
Crucially, the technology is running without subsidy, which is a major advance for carbon capture technology as for decades it has languished under high costs and lukewarm government support.
The firm behind the Tuticorin process says its chemicals will lock up 60,000 tonnes of CO2 a year and the technology is attracting interest from around the world.
