Main sources of carbon dioxide emissions 42.84 percent of all naturally produced carbon dioxide emissions come from ocean-atmosphere exchange. Other important natural sources include plant and animal respiration (28.56%) as well as soil respiration and decomposition (28.56%). A minor amount is also created by volcanic eruptions (0.03%).7 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil. The remainder results from the clearing of forests and other land use changes (9%), as well as some industrial processes such as cement manufacturing (4%).

The major sources for carbon dioxide emissions The major sources for carbon dioxide emissions. | Sourced From Helium |. Carbon dioxide is a common gas that comes from primarily natural sources, when a carbon atom combines with an oxygen molecule. It makes up a small, but important part of our atmosphere, which is primarily nitrogen and oxygen.

Where Does Carbon Dioxide Come From? Animals and microbes together release about the same amount of carbon dioxide as plants, while the oceans are the greatest single source. Only about 4 percent of carbon dioxide emissions come from artificial human sources. Carbon dioxide currently constitutes about 0.03 percent of Earth's atmosphere. Carbon dioxide is one of the crucial inputs for producers at the base of almost every food chain. The basic mechanism of photosynthesis is the use of solar energy to bond water and carbon dioxide into carbohydrates. Plants grow faster at higher carbon dioxide levels, since most of their structures are built from carbohydrates.

Bio-energy with carbon capture and storage The capture of carbon dioxide from bioenergy sources effectively removes CO2 from the atmosphere. Bio-energy is derived from biomass which is a renewable energy source and serves as a carbon sink during its growth. During industrial processes, the biomass combusted or processed re-releases the CO2 into the atmosphere.

Atmospheric carbon cycle The atmosphere is one of the Earth's major carbon reservoirs and an important component of the global carbon cycle, holding approximately 720 gigatons of carbon. Atmospheric carbon plays an important role in the greenhouse effect. The most important carbon compound in this respect is the gas carbon dioxide (CO2). Although it is a small percentage of the atmosphere (approximately 0.04% on a molar basis), it plays a vital role in retaining heat in the atmosphere and thus in the greenhouse effect.

The ins and outs of carbon dioxide. The ocean acts both as a source and a sink, releasing carbon dioxide and absorbing it through natural processes. Volcanic eruptions act as a natural source of CO 2. However, the amount of carbon released through volcanic eruptions is relatively small.

- What are the sources of carbon dioxide? Carbon Dioxide (or CO2) is created naturally by animals' breathing (respiration) and by the decay of plant and animal matter. These processes are natural sources of carbon dioxide in the atmosphere and account for about 38% of all CO2 emissions (Figure 1).

Greenhouse Gas Emissions: Causes & Sources The gases in the atmosphere that absorb radiation are known as greenhouse gases (sometimes abbreviated as GHG) because they are largely responsible for the greenhouse effect. The greenhouse effect, in turn, is one of the leading causes of global warming. The most significant greenhouse gases are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O), according to the Environmental Protection Agency (EPA).

- Carbon Dioxide. Carbon dioxide (CO2), which comes mainly from burning fossils fuels, is one of the top three greenhouse gases. Though not as high on the GWP scale as methane, CO2 accounts for the majority of greenhouse gas emissions in the United States -- 85 percent, noted Koerner.Vehicles are the biggest contributor.ethane, which comes from natural gas, landfills and cow flatulence, is one of the top three greenhouse gases, according to the Popular Science website. Methane has a Global Warming Potential (GWP) rating of 21.

Holocene extinction Carbon also exists in various forms in the atmosphere. Carbon dioxide (CO 2) is partly responsible for the greenhouse effect and is the most important human-contributed greenhouse gas. In the past two centuries, human activities have seriously altered the global carbon cycle, most significantly in the atmosphere.
