Green Energy Struggles to Halt Global Carbon Emissions from Reaching New High

"Adding" clean energy is struggling to replace fossil fuels

Recently, the UK's Energy Institute released its "Statistical Review of World Energy 2025." The report confirms a worrying trend: despite record-breaking investments in renewable energy and net-zero commitments from nearly all major economies, global carbon emissions reached a new high in 2024.

The report shows that global CO? equivalent emissions reached 40.8 billion tons in 2024, up 500 million tons from 40.3 billion tons in 2023, setting another record. Although renewable energy investment hit an all-time high and aggressive net-zero pledges continue to emerge from countries and corporations alike, global carbon emissions have been on an upward trajectory since 2021.

Over the past decade, even as international climate commitments have multiplied, global carbon emissions have still grown at an average annual rate of nearly 1%. News about rapid growth in wind and solar capacity frequently appears in the media, yet emission data reveals a clear reality: clean energy is expanding, but not fast enough to keep pace with rising global energy demand.

The report highlights deeper structural imbalances in global emissions when examining broader regional data. Over the past decade, Africa’s emissions grew by 25%; the Middle East by 15%; the Asia-Pacific region by over 9%; and South and Central America, often overlooked, by 9.3%. Except for North America, Europe has shown a clear downward trend, with average annual reductions of 1.4% over ten years. In 2024, the EU emitted 3.7 billion tons of CO?, 15% less than a decade ago. Countries like Germany and the UK have made continuous progress in reducing emissions through policy guidance, electrification, and improved energy efficiency. However, Europe’s success is uneven: Eastern and Southern Europe, facing economic pressures, have delayed some coal phase-out plans, resulting in flat or even rising emissions. While Europe is often seen as a benchmark for climate action, internal divisions reveal a reality: maintaining momentum on emissions reduction within a diverse union of nations is far from easy.

The report notes that these trends reflect not only differences in national policies but also patterns of population distribution and economic development: growth in global energy demand primarily comes from countries still building infrastructure, expanding transportation networks, increasing industrial output, and growing their middle classes.

Data from the report indicates that much-discussed energy transitions are progressing slowly and failing to curb emission growth. Wind and solar power are scaling up rapidly, but have not yet reached the level needed to displace fossil fuels and reduce total emissions—especially in developing countries. The report states that while clean energy has been "added" to the energy mix, fossil fuels have not been "subtracted," which is precisely why global emissions continue to rise. Unless global energy demand growth slows or renewables begin to replace fossil fuels at scale, emissions will keep climbing.
