10/16/2023 0 Comments Carbon dioxide definition![]() ![]() The addition of man-made greenhouse gases to the Atmosphere disturbs the earth's radiative balance. It is also a major source of ocean acidification since it dissolves in water to form carbonic acid. It is the reference gas against which other greenhouse gases are measured, thus having a Global Warming Potential of 1.īurning of carbon-based fuels since the industrial revolution has rapidly increased concentrations of atmospheric carbon dioxide, increasing the rate of global warming and causing anthropogenic climate change. It is the principal anthropogenic greenhouse gas that affects the Earth's radiative balance. A byproduct of fossil fuel combustion and biomass burning, it is also emitted from land use changes and other industrial processes. Data for carbon dioxide emissions include gases from the burning of fossil fuels and cement manufacture, but excludes emissions from land use such as deforestation.Ĭarbon dioxide (CO2) is naturally occurring gas fixed by photosynthesis into organic matter. Cement manufacturing releases about half a metric ton of carbon dioxide for each metric ton of cement produced. In combustion different fossil fuels release different amounts of carbon dioxide for the same level of energy use: oil releases about 50 percent more carbon dioxide than natural gas, and coal releases about twice as much. Anthropogenic carbon dioxide emissions result primarily from fossil fuel combustion and cement manufacturing. ![]() Available online at: Ĭarbon dioxide emissions, largely by-products of energy production and use, account for the largest share of greenhouse gases, which are associated with global warming. Washington, DC: World Resources Institute. ![]() They include carbon dioxide produced during consumption of solid, liquid, and gas fuels and gas flaring.Įmissions data are sourced from Climate Watch Historical GHG Emissions (1990-2020). Carbon dioxide emissions are those stemming from the burning of fossil fuels and the manufacture of cement. ![]()
