Climate TRACE reported that global greenhouse gas (GHG) emissions for August 2025 totaled 5.16 billion tons CO₂e, representing an increase of 0.40% vs. August 2024.
Total global year-to-date emissions are 41.09 billion tons CO₂e, which is 0.30% higher than 2024's year-to-date total.
Global methane emissions in August 2025 were 34.85 million tons CH₄, a decrease of 1.03% vs. August 2024.
Key takeaways:
· Climate TRACE’s preliminary estimate of August 2025 emissions in China, the world’s top emitting country, is 1.50 billion tons CO₂e, an increase of 4.89 million tons of CO₂e, or 0.33% vs. August 2024.
· Of the other top five emitting countries, United States emissions declined by 27.30 million tons CO₂e, or 4.54% year over year; India emissions increased by 0.91 million tons CO₂e, or 0.25% year over year; Russia emissions increased by 7.63 million tons CO₂e, or 3.10% year over year; and Indonesia emissions increased by 8.77 million tons CO₂e, or 7.02% year over year.
· In the EU, which as a bloc would be the fourth largest source of emissions in August 2025, emissions declined by 0.61 million tons CO₂e compared to August 2024, or 0.20%.
· Greenhouse gas emissions increased in August 2025 vs. August 2024 in agriculture, power, transportation, and waste, and decreased in fossil fuel operations. Transportation saw the greatest change in emissions year over year, with emissions increasing by 3.60% as compared to August 2024.
