India Eases SO2 Emission Rules for Power Plants

The government has changed the rules about how much pollution power plants can release.

Now, only some plants in big cities have to clean up their emissions.

Most plants don't have to, and the new rules are not very transparent.

The government says this is because cleaning up pollution is expensive and may not make a big difference, also arguing Indian coal is low on sulphur.

This has raised questions, especially for plants that already spent money on cleaning up emissions.
