Now That The Feds Are Malingering
Can States Help Save the Planet?

As the 2024 election threw national climate plans into uncertainty, 23 states didn’t wait for marching orders. Instead, they forged ahead with their own net-zero targets. Their motivation wasn’t idealism—it was pragmatism. A fractured Congress and whiplash presidential agendas made it clear: if carbon emissions were going to fall, the initiative would have to come from the ground up.

This isn’t theoretical. Using an energy system optimization model called Temoa, researchers tested two scenarios: one where those 23 states pursued net-zero emissions independently, and another where the federal government coordinated a unified national reduction strategy. The results? A 46% emissions cut either way—but with vastly different energy maps.

A New Era or a Temporary Patch?

Let’s name it: climate federalism. This concept, once an academic abstraction, now represents a practical path forward in a politically divided America. State-led action isn’t just a fallback. It’s become the proving ground for new technologies, tailored solutions, and political experimentation.

But this isn’t a kumbaya moment of cooperative governance. As Barry Rabe calls it, this is “contested federalism”—where states and the federal government may align, clash, or ignore each other altogether. And in this contest, some unexpected leaders are emerging.

Both scenarios achieved the same headline reduction: 45.7% by 2050. But the routes taken couldn’t be more different. State-led efforts leaned heavily on electrification—generating 952 terawatt-hours more electricity in 2050 compared to the federal model. Regions like California and the Northeast pushed direct air capture and expanded renewables. Others, less constrained by climate commitments, defaulted to fossil fuels.

This divergence matters. Where the federal plan sought efficiency across the board, state action resulted in a mosaic—some states building the future, others clinging to the past. And in this patchwork, the cost difference? Just 0.7%. Hardly the price of dysfunction.

The Hidden Cost: Emissions Leakage

Here’s where things get messy. In the fragmented landscape of state-led climate action, emissions don’t vanish—they shift. States without binding decarbonization goals, such as Texas and many across the Southeast, often ramp up fossil fuel production and energy exports to meet the increased demand in climate-committed states.

This means that while some states show declining emissions on paper, they may simply be outsourcing their pollution to neighboring regions. It’s a clever accounting trick with real-world consequences. The study estimates this cross-border emissions transfer—known as “leakage”—could amount to a staggering 439 million metric tons of CO2-equivalent by 2050. That’s not a minor footnote; it's a loophole big enough to drive a carbon-spewing freight train through.

This is the paradox at the heart of climate federalism. It empowers the willing—states that want to lead can forge ahead with innovation and ambition. But without federal guardrails, it also creates space for the unwilling to exploit the system. Regions that resist decarbonization can become energy exporters, turning their inertia into profit while undermining the national carbon ledger. In effect, the clean efforts of proactive states risk becoming camouflage for continued national emissions.

Without mechanisms like carbon border adjustments or emissions tracking across state lines, the system incentivizes exactly the kind of free-riding behavior that stalls global progress. Climate action becomes less a unified front and more a strategic shell game—where the emissions never really go away; they just change zip codes.

Why the Southeast May Hold the Key

Let’s talk about the Southeast. Politically hesitant, rich in biomass, and home to vast carbon storage potential, it remains underutilized—unless guided by federal incentive. Under the national plan, the Southeast delivered more emissions reductions than California and the Northeast combined. How? Through bioenergy with carbon capture and storage (BECCS), electrified transport, and a late but massive shift toward renewables.

With just 0.04% of GDP in costs, the Southeast became a climate powerhouse—when asked. Left to its own devices, it coasted. This suggests that targeted federal support, not blanket mandates, may be the golden key to unlocking reluctant regions’ potential.

Technology Isn’t the Problem—Policy Design Is

The divergence in approaches reveals something deeper than economics. It's about governance. States that want to lead can—and do. But the structure of emissions accounting, energy trading, and interregional transmission must adapt. Otherwise, we risk a system where clean states look green only because their dirty work is being done elsewhere.

Policy design must evolve. Border carbon adjustments, life cycle emissions tracking, and shared infrastructure investments can align incentives. We need to stop pretending emissions respect state lines. They don’t. Our policies shouldn’t either.

The Future Isn’t Uniform—It’s Interconnected

State-led decarbonization isn’t a second-best plan. It’s a distributed one. It trades uniformity for adaptability. It reveals regional strengths and political truths. And it points to a broader insight: deep decarbonization isn’t about one-size-fits-all blueprints—it’s about recognizing that transformation will look different in Baton Rouge than it will in Boston.

That flexibility is powerful. But it only works if we also design around its flaws. Emissions leakage, uneven investments, and technological inefficiencies must be counterbalanced by smart policy architecture. That’s the role federal intervention still plays—even if it no longer commands center stage.

In the end, the study’s most striking finding isn’t just the parity in emissions reductions or the marginal cost difference. It’s the political realism embedded in its scenarios. America is divided. But division doesn’t have to mean dysfunction. It can mean diversification. If we’re smart about it.

The race is on. Not between red and blue, but between inertia and action. And as it turns out, some of the most promising battlegrounds for that race aren’t in Washington—they’re in your state capitol.

Article Recap

The study reveals that *state-led decarbonization* can cut emissions nearly as much as a national plan—at almost the same cost. Though climate federalism creates regional differences in technology and carbon leakage risks, it also offers political resilience and cost-effective innovation. With proper federal incentives, reluctant states like Texas and the Southeast could unlock the next phase of U.S. climate leadership.
