IEA Outlook: CO₂ Emissions from Power Generation Set to Rise Over 1 % This Year

The IEA’s mid‑year outlook warns that global CO₂ emissions from electricity generation are set to rise by more than 1 % in 2023‑24, signaling a fresh risk premium for energy markets.

Global Emissions Trajectory and Market Impact

The report highlights that higher natural gas prices and a shift to coal—driven by supply cuts from the Middle‑East crisis—will push global emissions back upward.

■>1 % rise in global CO₂ emissions projected for the year.

■2 % increase in China due to high electricity demand and lower wind output.

■3.5 % decline in India last year, but 3 % rise expected this year.

■3 % drop in the United States, 5‑16 % decline forecast for the EU in 2026‑27.

Regional Takeaways: From Asia to the Americas

The global emission uptick reflects divergent energy mixes. Emerging economies like China and India continue leaning on fossil fuels, while the US and EU accelerate clean‑energy transitions.

■China: 2 % emission increase, carbon intensity 535 g/kWh → 495 g/kWh (2025‑2027).

■India: 3 % increase, carbon intensity ≈530 g/kWh → ≈500 g/kWh (2025‑2027).

■United States: 3 % decline, carbon intensity ≈450 g/kWh → ≈430 g/kWh (2025‑2027).

■EU: 5 % (2026) and 16 % (2027) emission cuts, carbon intensity 175 g/kWh → 135 g/kWh.

Carbon Intensity and Pricing Dynamics

Decarbonisation drives CO₂ pricing mechanisms and spot‑energy markets. The European Emissions Trading System (EU ETS) and US carbon credits reflect regional disparities.

■EU ETS price likely to hold around $80/tCO₂.

■US carbon credits trading in the $30‑$35/tCO₂ range.

■In Asia, rising coal demand could push spot‑coal prices up by 10‑15 %.

Outlook to 2027: A Declining Trend?

While global carbon intensity is expected to fall at an average 3 % annually, regional variances keep the picture complex. Emissions are set to hit new record levels, adding uncertainty to energy pricing.

■Global carbon intensity projected to drop to 410 g/kWh by 2027.

■EU: 135 g/kWh, China: 495 g/kWh, India: similar levels.

■Total electricity‑related emissions in 2027 will be less than half of 2017 levels.

Markets are likely to translate the IEA‑projected emission rise into a pricing risk, boosting volatility especially in regions with high carbon prices such as Europe and North America. HFT algorithms will be highly sensitive to sharp swings in coal and natural‑gas spot prices; swap markets will re‑price interest‑rate‑cut expectations amid energy‑demand uncertainty. In this environment, liquidity providers may tighten margin requirements on carbon‑emission contracts, potentially widening short‑term rate spreads.
