What I&#x27;d like to see - and never see suggested in these discussions - is starting with a revenue-neutral carbon tax to fund a BIG. Since the tax would internalize the externalities of pollution and climate change, the government could cut subsidies and tax breaks for energy production and efficiency, and throw those savings into BIG as well. Anyone willing to be a below-average greenhouse gas emitter comes out on top, while anyone who owns a private jet is doing well enough not to care.
