US Responsible for Nearly Half of Global CO2 Emissions Growth in 2025, Report Finds

A new analysis from the Energy Institute reveals that the United States accounted for nearly 50% of the world's carbon dioxide emissions increase in 2025, driven by the surge in AI data centers and policy shifts under the Trump administration.

The United States was responsible for nearly half of the global rise in carbon dioxide emissions in 2025, according to the 75th edition of the Statistical Review of World Energy published by the Energy Institute. The report highlights that the increase was largely fueled by the rapid expansion of AI data centers and what analysts describe as pro-pollution policies under the Trump administration.

Robert Rapier of OilPrice.com noted that the US accounted for almost 50% of the world's CO2 emissions growth last year. The finding underscores a significant reversal from previous years when US emissions were on a downward trend. The surge in electricity demand from data centers, particularly those powering artificial intelligence workloads, has led to increased reliance on fossil fuels.

Critics point to the Trump administration's rollback of environmental regulations and support for fossil fuel production as contributing factors. The report does not specify exact tonnage but emphasizes the disproportionate impact of US emissions on global totals.

The Energy Institute's analysis comes amid growing international pressure on the US to curb its carbon footprint. Environmental groups have called for stricter regulations on data center energy consumption and a transition to renewable sources. The report serves as a reminder of the challenges in balancing technological advancement with climate commitments.
