Carbon Emission Statistics and Facts (2025)

Introduction

Carbon Emission Statistics: Carbon emissions are a major cause of climate change. They mostly come from burning coal, oil, and gas. Cars, factories, power stations, and even homes release carbon into the air. Over time, the amount of carbon in the atmosphere has increased significantly. This leads to hotter weather, rising ocean levels, and stronger storms.

​In 2023, global carbon dioxide (CO₂) emissions from fossil fuels and industry reached approximately 37.01 billion metric tons, marking a continued upward trend in greenhouse gas emissions. China remained the largest contributor, accounting for over 31% of global CO₂ emissions. The United States and India followed, emitting significant portions of the total. The power sector was the leading source, responsible for 15 billion metric tons of CO₂ equivalent emissions. These escalating emissions have elevated atmospheric CO₂ concentrations to 419.3 parts per million, a 50% increase from pre-industrial levels.

The rise in greenhouse gas emissions contributes to global warming, resulting in increased temperatures, rising sea levels, and more frequent extreme weather events. Addressing these challenges necessitates comprehensive strategies to mitigate emissions across all sectors.

Carbon Budget to Limit Global Warming 2025 by Scenario

  • If we keep polluting like now, the world can only release about 235 billion tons of CO₂ before hitting the 1.5°C limit, which might happen in 6 years.
  • To keep global warming under 1.7°C, we could release up to 585 billion tons of CO₂, which would last around 14 years at today’s pace.
  • For the 2°C limit, the world could release 1,110 billion tons of CO₂, but if nothing changes, that budget might run out in 27 years.

Future Emission Reduction Targets by Country

  • The United States wants to cut emissions by 50–52% (compared to 2005 levels) by 2030 and reach net-zero emissions by 2050.
  • China plans to let its CO₂ emissions peak by 2030, not cut them yet, and aims for net zero by 2060.
  • The European Union has asked all 27 member countries to reduce greenhouse gas emissions by 55% by 2030. The long-term goal is to reach net-zero emissions by 2050.
  • Australia, among the highest polluters per person, has set a target to cut its emissions by 43% compared to 2005 levels by 2030. Like the EU, Australia also aims to achieve net-zero emissions by 2050.

CO₂ Emission Trading Contracts

co2-emission-trading-contracts (Reference: scoop.market.us)

  • According to Carbon Emission Statistics, CO₂ emission trading contracts increased in 2022 and 2023, reaching 90 and 91, respectively.
  • This steady rise is expected to carry on, with about 92 contracts predicted in 2024, 96 in 2025, and 102 in 2026.
  • The growth will likely continue, reaching around 104 contracts in 2027 and 108 in 2028.
  • But in 2029, a small decline is expected, bringing the number down slightly to 107 contracts.

Sustainable Initiatives of Carbon Emission Statistics

  • In 2024, the European Union’s Emissions Trading System (ETS) reported a 5% drop in carbon dioxide emissions due to a 12% decrease in the power sector. This progress aligns with the EU’s goal of a 62% reduction by 2030.
  • Revenues from carbon pricing mechanisms, such as taxes and emission trading systems, reached a record USD 104 billion in 2023.
  • The United States saw a minimal decrease of 0.2% in greenhouse gas emissions in 2024, despite a 2.7% economic growth.
  • Carbon dioxide emissions from fossil fuels hit a new high of approximately 37.4 billion tons in 2024, marking a 0.8% increase from the previous year.
  • In 2024, clean energy sources supplied over 40% of global electricity demand for the first time since the 1940s, driven by significant solar and wind power growth.
  • Sectors covered by the EU-ETS have reduced emissions by approximately 50% since 2005.
  • An increase of USD 10 per ton in carbon taxes has been associated with a 1.3% short-term and 4.6% long-term reduction in per capita CO₂ emissions.
  • In 2024, aviation emissions under the EU ETS rose by about 15%, partly due to the system’s inclusion of more international flights.

Conclusion

To sum up, carbon emissions are a big problem for our planet. Most come from cars, factories, and burning fuels like coal and oil. These emissions trap heat and make the Earth warmer, which leads to climate change.

But the good news is that we can still do something about it. We can use clean energy sources like solar or wind, drive less, and turn off lights and electronics when we don’t need them. Planting trees is also a great way to help because trees soak up carbon dioxide from the air.

Even small actions make a difference. If everyone does a little, it can add up to a lot. Let’s all take steps now to keep our planet safe and healthy for the future. The time to start is now, before things get worse.
