Brilliant reporting by @Sushmitav1 @Source_Mat @lukewbarratt on the extension received by one of Mumbai's most polluting (coal) power plants, owned by Tata, citing increased need for its data centres, even as a toxic cesspool of a locality, which was once a fishing village,

A tip-off led us to uncover one of Britain’s most overlooked environmental scandals: UK tyre exports ending up in illegal pyrolysis plants burning rubber to produce toxic oil. India had banned imports in 2022, yet our analysis of trade data showed shipments continued to surge.
