Exactly! One scientist I spoke to previously said upto 50-60% of aerosol composition over India was SO2. I’m surprised by this report now saying sulfate emissions are fine.
I think the trade off between reducing sulphur pollution and the costs incurred in doing so - cash, increased use of fresh water and higher CO2 emissions is what's driving this policy change. India urgently needs to move away from fossil fuels to renewables.
