European brands and companies will no longer be able to cite weak claims of carbon offsetting as regulations to battle greenwashing practices are tightened.

This is peak "I don't understand what this is about, buti still have an opinion".

Companies are paying for a fake seal of greeness. The law will not allow fake green washing, so companies will stop spending money on it. Surely prices should go down, right?

And you understand, why it is preferable that prices go up and actual green products are sold to pseudo - green products at a lower price, right?

Of course there's a reason. It's called fraud. If they sell not so "green" products, then greenwashing is fraud, plain and simple.

They are still allowed to sell those not so green products for cheap, but they are no longer allowed to outright lie about the colour.

That’s ok. Then the actual green products will not rise as much as the not so green products.
