However, since the industrial revolution, more and more CO2<br \/>has ended up in the atmosphere as a result of the increasing use of fossil<br \/>fuels; the current concentration is 370 ppmv. Furthermore, it is<br \/>estimated that if nothing changes, by 2100 this concentration will be<br \/>approximately 750 ppmv. It is thus assumed that the CO2 concentration<br \/>in the atmosphere will rise to an unacceptable level in the next 500<br \/>years, as this rise will lead to a global strengthening of the greenhouse<br \/>effect and associated climate change.<\/p>\n<p>One of the results of the 1997 Kyoto Climate Conference was the<br \/>commitment by all EU countries to reduce annual emissions of<br \/>greenhouse gases (including CO2) in the period 2008-2012 by eight<br \/>percent with respect to the 1990 level. In 1998, the Netherlands agreed<br \/>to this under certain conditions, and the joint objective was translated<br \/>into a national reduction of six percent with respect to the 1990 level, to<br \/>be achieved in the period 2008-2012.<\/p>\n<p>Sources<br \/>The average worldwide anthropogenic emission of CO2 is approximately<br \/>7.4 gigatons C per year (1997). This will rise to 26 GtC\/year by 2100 (1<br \/>gigaton is 109 ton). The total emission of CO2 for the Netherlands in<br \/>2000 was 50 Mt C (106 ton).<\/p>\n<p>Sources of CO2 include: power stations, industry, homes, traffic and<br \/>transport, agriculture and horticulture, gas and oil extraction. The<br \/>emissions of v by large point sources, such as heavy industry and power<br \/>generation represent about a third of total worldwide anthropogenic<br \/>emissions; in the Netherlands this accounts for about 56 percent.<br \/>Reducing the concentration of CO2 in the atmosphere can be achieved<br \/>in various ways, for instance by economising on energy use or by<br \/>producing more materials in which carbon is sequestered for a long<br \/>period of time (e.g. plastic and wood). In the short term, possible<br \/>options include sequestering CO2 in seawater and in the ground or the<br \/>seabed under conditions that prevent its uncontrolled leakage back into<br \/>the atmosphere.<\/p>\n<p>Two important CO2 releasing processes can be distinguished: burning of<br \/>organic matter and separation of CO2 from other gasses. By nature,<br \/>natural gas contains up to 70% CO2, which must be removed before<br \/>the gas can be used by the consumer. Sequestration of CO2 in seawater<br \/>or bottom needs pure CO2. From a technical point of view it is possible<br \/>to separate CO2 from other gasses. However, this process needs energy<br \/>and consequently an additional release of CO2. It is estimated that<br \/>about 30% more CO2 is produced in this purifying process. A complete<br \/>Sequestration of carbon dioxide (CO2) in the Dutch part of the North Sea<\/p>\n<p>Life Cycle Analysis, comparing the efficiency of different matter and<br \/>energy fluxes, is net yet performed. In addition it is remarkable that in the literature studied, only the sources, path and fate of CO2 as a gas is followed, and little is mentioned about the fate of other (greenhouse) gasses (e.g. nitrogen<br \/>and sulphur oxides).<\/p>\n<p>This memorandum evaluates the pros and cons of sequestering carbon in the sea and the possible associated risks.
