Immediate carbon removal would eliminate all climate damages. Delay it 25 years and you only get half the benefit. That’s the headline finding from a new Stanford study published in Nature, and it’s the most powerful economic argument for CDR deployment I’ve seen.

The researchers built a framework linking individual emissions to actual, quantifiable global damages. The numbers are staggering, specific, and uncomfortable.

The damage ledger

Since 1990, US emissions have caused $10 trillion in global damages. Not theoretical future costs — realized economic harm distributed across the planet:

  • $1.39 trillion in damages to the EU
  • $500 billion to India
  • $330 billion to Brazil

The US isn’t just an emitter. It’s the source of measurable economic destruction in specific countries, with specific dollar amounts attached.

The irony: the US itself has suffered $16.2 trillion in damages from all global emissions — including $2.97 trillion from its own. America is simultaneously the biggest damager and one of the biggest damaged.

The exponential cost of delay

Here’s where CDR people need to pay attention.

One tonne of CO₂ emitted in 1990 caused $180 in damages by 2020. That same tonne will cause $1,840 in damages by 2100. Past emissions don’t stop causing harm — they compound. Every year of warming stacks on top of every previous year.

Now apply that to carbon removal timelines:

  • Immediate CDR deployment → eliminates all future damages from removed CO₂
  • 25-year delay → only eliminates 50% of damages

Read that again. Waiting 25 years to do what we could do now cuts the benefit in half. Not because the technology degrades — because the damages accumulate faster than removal can offset them once they’ve started cascading.

This is the economic case for CDR urgency that the industry has been missing. It’s not just “removal is good.” It’s “every year of delay has a specific, enormous price tag.”

The billionaire footnote

The study also quantified individual emissions. Private jet usage by Gates, Musk, and Bezos each generates over $1 million in climate damages by 2100. Per person. From jets alone.

It’s a vivid illustration, though the real policy relevance isn’t about shaming billionaires. It’s that the framework works at every scale — individual, corporate, national — with real dollar amounts. Climate damages are no longer abstract. They’re accounting.

What this means for CDR investment

If delaying carbon removal by 25 years costs trillions in unrealized damage prevention, then the question isn’t “can we afford CDR?” It’s “can we afford not to deploy it immediately?”

The current global CDR investment is maybe $10-15 billion annually. The study suggests the damages from delayed action are orders of magnitude larger. At those ratios, even expensive CDR methods — DAC at $400-600/tonne — look like a bargain compared to the alternative.

Every year the CDR industry argues about costs, permanence, and methodology while deployment stalls, the damage clock is running. Stanford just put a number on the bill.
