Not even 1%. The USA alone pollutes a ton more and is always utterly unapologetic about it. Historically I don't think they ever adhered to any global effort or treaty to reduce pollution. You have big entrenched organizations such as the oil industry doing far more damage and nobody messes with them. Not to mention the entire developed world's dependency on China for their borderline useless cheap consumer products.

This concern over the environmental impact of cryptocurrencies is utterly laughable when you figure out the real source of these problems. I guess they're just too powerful to be messed with.

> Nobody messes with them.

Well, some environmental activists try by turning off oil valves[0], just like environmental activists are upset with Bitcoin.

> You have big entrenched organizations such as the oil industry doing far more damage.

People who criticize Bitcoin for its environmental impact don't give a pass to oil companies. The issues overlap, like in Texas where they plug Bitcoin mining rigs straight into the oil well[1].

But I hear you. All big entrenched organizations must be held accountable. Of course.

The problem isn't even bitcoin mining, it's pollution. The energy usage wouldn't matter at all if it was generated via renewable sources such as solar.

People who want to see real change need to deal with fossil fuels. Taxing mining operations will do absolutely nothing to solve the actual problems of this world.
