Climate Trace, a coalition formed by a group of AI specialists and supported by more than 100 other contributing organizations and researchers, reported that global greenhouse gas emissions for February 2025 totaled 5.04 billion tons CO2e. This represents a decrease of 0.47 percent vs. February 2024. It should be noted that, as a leap year, February 2024 was one day longer than February 2025, and therefore had one additional day’s worth of emissions. Total global year-to-date emissions total 10.32 billion tons CO2e. This is 0.55 percent lower than the previous year-to-date total for the first two months of 2024. Global methane emissions in February were 31.70 million tons — a 0.01 percent decrease compared to February 2024.

Greenhouse gas emissions by country: February 2025

Climate Trace’s preliminary estimate of February 2025 emissions in China, the world’s top emitting country, is 1.47 billion tons CO2e, which increased by 3.04 million tons of CO2e or 0.21 percent compared to February 2024.

Of February 2025’s other top five emitting countries:

  • USA emissions declined by 6.88 million tons CO2e, or 1.18 percent year over year;
  • Russia emissions declined by 2.06 million tons CO2e, or 0.63 percent year over year;
  • India emissions declined by 1.97 million tons CO2e, or 0.63 percent year over year;
  • Indonesia emissions declined by 0.87 million tons CO2e, or 0.72 percent year over year.
  • In the EU, which as a bloc would be the third largest source of emissions in February 2025, emissions declined by 2.63 million tons CO2e compared to February 2024, or 0.79 percent.

Greenhouse gas emissions by sector: February 2025

Greenhouse gas emissions increased year over year in buildings and decreased in fossil fuel operations, manufacturing, power, and transportation. Transportation saw the greatest change in emissions year over year, with emissions declining by 1.29 percent.

  • Agriculture emissions were 554.62 million tons CO2e, unchanged vs. February 2024;
  • Buildings emissions were 438.59 million tons CO2e, unchanged vs. February 2024;
  • Fossil fuel operations emissions were 870.79 million tons CO2e, a 0.39 percent decrease vs. February 2024;
  • Manufacturing emissions were 873.74 million tons CO2e, a 0.13 percent decrease vs. February 2024;
  • Mineral extraction emissions were 21.89 million tons CO2e, unchanged vs. February 2024;
  • Power emissions were 1,256.30 million tons CO2e, a 0.79 percent decrease vs. February 2024;
  • Transportation emissions were 696.78 million tons CO2e, a 1.29 percent decrease vs. February 2024;
  • Waste emissions were 192.56 million tons CO2e, unchanged vs. February 2024.
