About 36.6 billion tons per year
- The main driver of increasing atmospheric CO 2 is the burning of fossil fuels, with emissions increasing from 10.9 billion tons per year in the 1960s — which is when the measurements at the Mauna Loa Observatory in Hawaii began — to about 36.6 billion tons per year in 2022, according to the Global Carbon Project, which uses NOAA’s greenhouse gas measurements in its estimates.

Apr 5, 2023 · Levels of carbon dioxide (CO 2 ), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.
Mar 2, 2023 · Global energy-related CO 2 emissions grew by 0.9% or 321 Mt in 2022, reaching a new high of over 36.8 Gt. Following two years of exceptional oscillations in energy use and emissions, caused in part by the Covid-19 pandemic, last year’s growth was much slower than 2021’s rebound of more than 6%.

The Global Carbon Project estimates that global emissions of CO2 – including land use and fossil CO2 – will remain relatively high at 40.5GtCO2 in 2022, but still below their 2019 peak of 40.9GtCO2. The authors note that these emissions “are approximately constant since 2015” due to a modest decline in land-use emissions balancing out modest increa...
Despite a relatively modest increase of 1.0% in 2022 (with an uncertainty range of 0.1% to 1.9%), global fossil CO2 emissions will likely surpass the pre-pandemic high in 2019 to set a new record at 36.6GtCO2. This represents a continued recovery in global emissions from the declines during the Covid-19 pandemic in 2020, as well as a failure of hop...
Global fossil fuel emissions primarily result from the combustion of coal, oil and gas. Coal is responsible for more emissions than any other fossil fuel, representing approximately 40% of global fossil CO2 emissions in 2022. Oil is the second largest contributor at 32% of fossil CO2, while gas and cement production round out the pack at 21% and 4%...
Every year, the Global Carbon Project provides an estimate of the “global carbon budget”. This budget is based on estimates of the release of CO2 through human activity and its uptake by the oceans and land, with the remainder adding to atmospheric concentrations of this greenhouse gas. (This differs from the commonly used term “remaining carbon bu...
Nov 10, 2022 · This year, nations are projected to emit roughly 36.6 billion tons of planet-warming carbon dioxide by burning coal, natural gas and oil for energy, according to new data from the Global Carbon...
Mar 13, 2023 · Global CO 2 emissions in 2022. In 2022, global CO 2 emissions from fossil fuel combustion and cement production reached 36.1 ± 0.3 GtCO 2 (Fig. 1 ). In comparison, emissions were...
Mar 2, 2023 · Emissions of the climate-warming gas that were caused by energy production grew 0.9% to reach 36.8 gigatons in 2022, the International Energy Agency reported Thursday. (The mass of one gigaton is equivalent to about 10,000 fully loaded aircraft carriers, according to NASA.)
