How have global emissions of carbon dioxide (CO 2) changed over time? In this chart, we see the growth of global emissions from the mid-18th century through to today. We see that before the Industrial Revolution, emissions were very low.
Human emissions of greenhouse gases are the primary driver of climate change today.1. CO2 and other greenhouse gases like methane and nitrous oxide are emitted when we burn fossil fuels, produce materials such as steel, cement, and plastics, and grow the food we eat.
Total greenhouse gas emissions are the sum of emissions of various gases: carbon dioxide, methane, nitrous oxide, and smaller trace gases such as hydrofluorocarbons (HFCs) and sulfur hexafluoride (SF6). How much does each gas contribute to global greenhouse gas emissions?
2 mar 2023 · CO 2 growth in 2022 was well below global GDP growth of 3.2%, reverting to a decade-long trend of decoupling emissions and economic growth that was broken by 2021’s sharp rebound in emissions. Improvements in the CO 2 intensity of energy use were slightly slower than the past decade’s average.
21 mar 2022 · Following record-level declines in 2020, near-real-time data indicate that global CO2 emissions rebounded by 4.8% in 2021, reaching 34.9 GtCO2.
4 kwi 2024 · Global CO2 emissions for 2023 increased by only 0.1% relative to 2022 (following increases of 5.4% and 1.9% in 2021 and 2022, respectively), reaching 35.8 Gt CO2.
1 mar 2024 · CO 2 Emissions in 2023 provides a complete picture of energy-related emissions in 2023. The report finds that clean energy growth has limited the rise in global emissions, with 2023 registering an increase of 1.1%.
