For U.S. climate activists to succeed, they must demand serious government spending on energy efficiency and renewables—spending comparable to the current war budget. Calling for hundreds of billions in annual green public investment has potential for the popular appeal needed to build a powerful grassroots climate movement. That investment would be the best policy as well. Massive clean energy spending would not only provide jobs and economic growth on a grand scale. It is the most effective way to reduce greenhouse gas pollution.
It is widely, though not universally, acknowledged that solving the climate crisis will require public investment and subsidies, efficiency regulations and clean energy requirements, plus a price on greenhouse gas emissions. (The idea behind a carbon price: polluters pay per unit of greenhouse gas pollution released.) But, in practice, policy advocates tend to fetishize the carbon price and drop other requirements. For example, James Hansen, perhaps the world’s leading climate scientists says “If we would put this price on carbon it would favor renewables, and it would favor energy efficiency, and it would favor nuclear power—it would favor anything that is carbon-free… ”[i] Charles Komanoff and James Handley of the Carbon Tax center describe a carbon tax as the “sine qua non of effective climate policy”.[ii] Mainstream environmentalism tends to favor cap-and-trade over carbon fees, which indirectly results in a price on carbon. Between carbon tax and cap-and-trade advocates, most climate change opponents prioritize carbon pricing. Few join Komanoff in referring to such pricing as the “sine qua non” of carbon policy. In policy discussions, however, most environmental economists start with cap-and-trade or a carbon fee, and many never discuss anything else.
