Focusing on CO² is an oversimplification, yes, and carbon credits are just ways corporate are monetizing on us. Yet we still have many other pollutants. SO² for example comes directly from our hands digging those fossil fuels and pumping them as diesel , kerosene and coal. And metrics shows we do very little to reduce usage of these 3.

Sometimes its odd how industries are focusing on EV cars which already running on petrol (petrol is way cleaner than the other 3 fossil fuels).
