The predominant share of CO2 in the global anthropogenic GHG emissions has been recognised. The need to reduce CO2 emissions has led to the development of several technologies such as carbon capture and storage (CCS), which aim at capturing the CO2 emitted by industries and store it underground. However, waste treatment companies are not currently encouraged to install CCS on their facilities since they do not have to pay for the CO2 they emit. Nevertheless, if the captured CO2 is re-used (Carbon capture and utilisation (CCU)) it could possibly represent a source of income for the waste company.
So, the aim of CCS is to prevent the release of large quantities of CO2 into the atmosphere (from fossil fuel use in power generation and other industries). It is a potential means of mitigating the contribution of fossil fuel emissions to global warming and ocean acidification.
