Fossil Fuel Emissions Dip in 2026, But Not Thanks to Green Energy

This year's cut is smaller than either. The researchers project global emissions will reach 38.24 gigatons by year's end — roughly 0.16 gigatons less than 2025.

What did the study actually measure?

Peters and his colleagues collected data on countries' electric vehicle stocks and on wind and solar generation, then projected how those technologies affect global fossil CO2 emissions through 2028. CO2, or carbon dioxide, is the main heat-trapping gas released by burning coal, oil and gas.

One detail deserves a flag. The team used the generative AI model Claude to source data and write the analysis code. The paper doesn't dwell on the limitations of that approach, and readers should weigh the projections accordingly. AI-assisted analysis is increasingly common in research, but it's a method worth noting, not glossing over.

Is the energy transition working at all?

Yes — more than headline cynicism suggests. The study found that without EVs, solar and wind, global emissions would have risen by 1.9 percent per year on average from 2019 to 2025. That's more than double the actual growth rate of 0.8 percent.

And if electric vehicle sales and solar and wind capacity keep growing at their 2026 rates, those technologies should counteract about 63 percent of emissions growth from 2025 to 2028. In plain terms, that's about 1.64 gigatons of added emissions avoided.

So the transition is bending the curve. It just isn't bending it downward on its own — not yet.

What does this change for the climate outlook?

For now, not much. The researchers conclude that the energy transition needs to accelerate before humanity sees emissions decline consistently, year after year, without a crisis doing the work. Clean technologies are already offsetting a large share of growth. But offsetting growth isn't the same as shrinking emissions.

The timing of peak emissions — the point at which emissions stop rising for good — remains genuinely uncertain. "It's very hard to say exactly how long it will take," Peters said.

Still, he sees a signal in the conversation itself. "The fact that we're talking about this means that we're close to that point."

Maybe. Peak emissions talk has circulated before, and projections through 2028 rest on growth rates holding steady. The honest read: the numbers are moving in the right direction, the cause this year isn't, and the real test arrives when oil prices fall back to normal.
