Climate protection is the most important reason for developing CO2 capture and storage.In particular sectors of the economy other economic incentives to capture CO2 already exist today (e.g. enhanced oil recovery). Attitudes towards the technology are not uniform in different groups of society. CCS is often described as a possible bridge to the era of renewable energy. Environmental organisations prioritise the further expansion of renewables and the full exploitation of energy-saving potentials. All environmental organisations reject the ideaof storing CO2 in the oceans. Adequate proof of long term stability is demanded for all storage options.
