The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.0427%) on a molar basis in 2024, representing 3341 gigatonnes of CO 2. [1] This is an increase of 50% since the start of the Industrial Revolution , up from 280 ppm during the 10,000 years prior to the mid-18th century.
Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
The Integrated Carbon Observation System (ICOS) is a research infrastructure to quantify the greenhouse gas balance of Europe and adjacent regions. In November 2015 it received the international legal status of ERIC ( European Research Infrastructure Consortium ) by decision of the European Commission. [ 1 ]

Accordingly, a proportion of the CO 2 produced and reported in Asia and Africa is for the production of goods consumed in Europe and North America. [14] Greenhouse gases (GHG) – primarily carbon dioxide but also others, including methane and chlorofluorocarbons – trap heat in the atmosphere, leading to global warming.
