Carbon sinks are reservoirs that hold carbon and can be natural or man-made. Oceans and vegetation are natural sinks, while landfills are man-made. Carbon control experts are investigating the use of sinks to limit carbon emissions, with the largest global factor being the oceans. Increasing vegetation is also valuable. Landfills are being evaluated for effectiveness, and in Europe, landfill regulations are affected by the Kyoto Protocol. Scientists are identifying practical strategies to reduce humanity’s carbon footprint, and carbon sinks are just one tool in the arsenal of carbon dioxide and greenhouse gas control.
A carbon sink is any type of reservoir that holds a carbon-bearing element. Carbon sinks are often used to keep carbon emissions out of the atmosphere. A carbon sink can be a natural or man-made construction.
Natural locations of carbon sinks include oceans, which naturally contain carbon dioxide, and patches of vegetation that consume carbon dioxide. Man-made carbon sinks include landfills and other specialized reservoirs for carbon materials. Public officials are now looking into both types of carbon sinks as ways to limit carbon emissions.
The recent Kyoto Protocol, ratified by almost all the nations of the world, considers the containment of carbon dioxide an absolute priority. Those who are looking to implement practical reductions in carbon emissions are investigating the use of carbon dioxide sinks as a possible solution. Looking at the role of the oceans, it has become clear that the carbon-holding potential of these natural carbon sinks is the largest global factor in controlling the elements of carbon.
Carbon control experts are also discovering significant value in increasing vegetation on the earth’s surface. Carbon sinks in forests consume huge amounts of carbon dioxide and provide organic raw materials that are consumed by the human population every day. To support natural areas of carbon sinks, experts continue to look to increase carbon control, or “sequestration,” the globe’s capacity with man-made carbon sinks.
An important part of evaluating the effectiveness of landfills as carbon sinks is to study how much carbon in consumables is released into the atmosphere between the time of production and its eventual addition to a landfill space. Theoretically, items that don’t release any of their carbon emissions would be carbon neutral in a landfill of carbon sinks, but critics argue that’s almost never the case.
In Europe and other nations that have ratified the Kyoto Protocol, carbon reduction issues affect the types of materials that can be placed in a landfill. In the United States, where the Kyoto Protocol does not regulate municipal procedures, the main landfill problems concern toxicity, the practical containment of heavy metals and other public health problems. All over the world, those involved in analyzing carbon emissions and climate change are trying to identify practical strategies to reduce humanity’s total carbon footprint.
Public officials in many countries can expect to hear from scientists more often about the most practical ways to use carbon sink options for carbon dioxide sequestration in the future. Carbon sinks are just one tool in an arsenal of allergens that include many elements of carbon dioxide and greenhouse gas control. Legislative efforts such as the US “cap and trade” proposal work to increase the world’s ability to limit carbon emissions.
