5. Conclusion

CO ₂ capture, combined with geological storage, is a technology that is fully in line with the objectives of reducing greenhouse gas emissions limiting global warming. In its 2014 report , the IPCC considers that, without the use of CCS, achieving the target of 450 ppm CO _2eq in the atmosphere corresponding to an increase of 2°C by 2100 will require considerable effort, or even, depending on the modeling tools considered, will not be possible. It is therefore one lever, among many others, that must be activated if we are to achieve ambitious climate targets...
