Carbon Capture and Storage: A Controversial Climate Mitigation Approach

As the threats of climate change grow, the need to reduce carbon dioxide (CO2) emissions from fossil fuel burning is increasingly acknowledged by governments around the world. The potential of carbon capture and storage (CCS), a set of technologies that offers a politically appealing vision of a ‘cleaner’ way to use fossil fuels, has provided powerful motivation for large public and private investments in CCS technology. But investing in CCS is controversial because, although some consider it a critical climate mitigation technology, others view it as an expensive fossil fuel subsidy that could inadvertently perpetuate, rather than reduce, fossil fuel reliance.
