PROSPECTS FOR CO 2 CAPTURE AND STORAGE Energy Technology Scenarios Public awareness and acceptance The deployment of CCS technologies will require broad understanding and long-term commitment by numerous constituencies Environmental NGOs generally support RD&D work on CCS technologies Their main concern centres on the fact that CCS is seen and presented as a solution which would allow for the continued use of fossil-fuel resources as long as they are available

PROSPECTS FOR CO 2 CAPTURE AND STORAGE Energy Technology Scenarios The regulatory and legal framework Countries should create an enabling legal and regulatory environment for national CO 2 storage projects. Contracting parties to international instruments should be proactive in clarifying the legal status of CO 2 storage in the marine environment, taking into consideration their objectives to stabilize CO 2 in the atmosphere.
