China turns to households in fight to slash carbon emissions

VOLUNTARY VS COMPULSORY

I know which I would put my money on in the long run. No charging for your EV this week, you have exceeded your "fair share" of energy for the week.

What a senseless attempt. Of course the installation of those coin, token or voucher systems as well as the production and distribution of those prize goods etc consume the next energy and bring the next loads of carbon. They trick themselves or use those campaigns as an alibi in front of international meetings on carbon or climate issues, but that is all on this useless attempt.
