Did Democrats Just Save Civilization?

They really did it. The Inflation Reduction Act, which is mainly a climate change bill with a side helping of health reform, passed the Senate on Sunday; by all accounts it will easily pass the House, so it’s about to become law.

This is a very big deal. The act isn’t, by itself, enough to avert climate disaster. But it’s a huge step in the right direction, and sets the stage for more action in the years ahead. It will catalyze progress in green technology; its economic benefits will make passing additional legislation easier; it gives the United States the credibility it needs to lead a global effort to limit greenhouse gas emissions.

There are, of course, cynics eager to denigrate the achievement. Some on the left rushed to dismiss the bill as a giveaway to the fossil fuel industry posing as environmental action. More important, Republicans — who unanimously opposed the legislation — are shouting the usual things they shout: Big spending! Inflation!

But actual experts on energy and the environment are giddy over what has been accomplished, and serious economists aren’t worried about the effect on inflation.

Start with the environmental side. Many people I talk to assume that President Biden’s environmental agenda, as contained in his original Build Back Better proposal, must have been greatly watered down in the legislation we actually got. After all, didn’t Democrats have to make big concessions to win over Senator Joe Manchin? Aren’t there important giveaways to fossil fuel interests, like aid for a controversial natural gas pipeline?

However, energy analysts believe that any adverse climate effect from these concessions will be swamped by the gains from tax credits for clean energy. The REPEAT Project, compiled by Princeton’s ZERO Lab, has produced a side-by-side comparison of emissions cuts under the Inflation Reduction Act and the earlier House version of Build Back Better. By 2035 the I.R.A., they estimate, will have delivered more than 90 percent of the emissions reductions that B.B.B. would have achieved. After all that legislative drama, Biden’s climate policy has emerged essentially intact.

How was this possible? Right at the beginning, the Biden administration decided that its climate policy would be all carrots, no sticks — that it would provide incentives to do the right thing, not penalties for doing the wrong thing. This strategy, it was hoped, would prove politically feasible in a way that, say, a carbon tax wouldn’t. And this hope has been vindicated.

Furthermore, it’s a strategy that seems likely to pay political dividends in the future. One new study, by E. Mark Curtis and Ioana Marinescu, finds that “the growth of renewable energy leads to the creation of relatively high paying jobs, which are more often than not located in areas that stand to lose from a decline in fossil fuel extraction jobs.”

So what did the Biden administration lose? Unfortunately, much of the social spending B.B.B. originally included — child tax credits, universal pre-K and more — was cut. That’s tragic, although enhanced health insurance subsidies — which have helped bring America’s uninsured rate to a record low — have been extended. But Democrats delivered on their climate promises, more or less in full.

What about the critique from the right? Aside from the pathetic attempt to portray the I.R.A. as a big tax hike on the middle class, Republicans like Mitt Romney are trying to lump this legislation in with last year’s American Rescue Plan, which they claim caused inflation to spike.

Never mind whether this claim is true. The key thing is to do the math. The Inflation Reduction Act calls for spending less than $500 billion over a decade, compared with the American Rescue Plan’s $1.9 trillion in a single year — and will actually reduce the deficit. That’s why independent analysts find that it will have little effect on inflation.

But if the spending isn’t very large, how can it have such a big impact? The answer is that right now we’re sitting on a sort of cusp. Renewable energy technology has made revolutionary progress, and renewables are already cheaper in many areas than fossil fuels. A moderate push from public policy is all that it will take to transition to a much greener economy. And the Inflation Reduction Act will provide that push.

Given all this, however, why did every single Republican senator vote against the I.R.A.? They aren’t all ignorant and innumerate; I’m pretty sure that Romney, for example, knows that he’s talking nonsense.

Nor can we easily invoke differences in ideology. The I.R.A.’s climate push mostly relies on tax credits — and Republicans have themselves used tax credits to achieve social goals, like the (much abused) Opportunity Zone credits in Donald Trump’s 2017 tax cut.

Almost surely, what we’re really looking at is the politics of spite. Every Republican in the Senate was willing to kill our best chance at avoiding climate disaster, simply to deny the Biden administration a win.

The good news is that the legislation passed in spite of their spite. And the world is a more hopeful place than it was just a few weeks ago.
