The United States accounted for 50% of the world's increase in emissions last year.
And it was driven by data centers.
While many assume China is driving the world's rising carbon emissions, the latest energy data reveals that the United States played a far larger role last year. According to the Energy Institute's 2026 Statistical Review of World Energy, North America accounted for 47% of the global increase in carbon emissions during 2025, with the U.S. responsible for almost all of that growth.
Despite a 28% surge in domestic solar capacity, clean energy was unable to keep up with skyrocketing power demand, causing U.S. coal-related emissions to jump by 13%.
This dual growth of fossil fuels and renewables demonstrates that green energy alone cannot curb emissions if overall electricity consumption rises faster than clean generation can scale.
The primary driver of this massive energy demand is the rapid expansion of the artificial intelligence industry. The report highlights that the U.S. is home to roughly 40% of global data center electricity consumption as tech companies race to construct the infrastructure necessary to power advanced AI models.
This massive digital expansion has created an environmental paradox for the tech sector: while major companies publicly pledge to reduce their carbon footprints, their insatiable demand for computing power is actively driving a national resurgence in fossil fuel reliance. Striking a balance between pioneering technological innovation and building a clean, capable electrical grid remains one of the most critical challenges of the modern era.
