Dozens of projects are in development across US despite concerns over environmental and health risks

While international climate monitors say carbon sequestration projects could be secondary tools to help contain global warming, they also say the main focus must be on urgent and deep cuts to fossil fuels. Some environmental groups question the benefits of carbon sequestration and are concerned it could delay the transition to clean energy and pose risks to surrounding communities.

Environmental experts say the risks of carbon storage include earthquakes, water table contamination and potentially deadly carbon leaks, and point to several cases where carbon has leaked.

Oil companies are lobbying hard for the projects, […]

People will do literally anything other than plant trees.

Or here’s an option, price in the externalities! Beef is now $300/lb, and everyone goes vegan. Global warming averted.

This community is evolving from being just about CDR to include all CO₂ capture, removal, utilization, sequestration & storage technologies. So let’s discuss everything related to:

Carbon Capture and Storage (CCS)
Carbon Capture, Utilization, and Storage (CCUS)
Direct Air Capture (DAC) / Direct Air Carbon Capture and Sequestration (DACCS)
Carbon Dioxide Removal (CDR) / Greenhouse Gas Removal (GGR)
etc

While many climate scientists have reservations about CCS, the crisis has now grown so acute that almost all the net zero pathways modeled by the U.N.-backed Intergovernmental Panel on Climate Change (IPCC) and the Paris-based International Energy Agency (IEA) envision huge deployments of the technology by mid-century. Governments have also embraced the prospect that CCS could be a cost-effective means for reducing emissions without disrupting fossil fuel-based economies.[1]

Perhaps, it could be considered alarming that these technologies are often intertwined with fossil fuel companies. These corporations use them as an excuse not to phase out their production, while portraying themselves as part of the solution. (see: Exxon Mobil, BP, Shell, Chevron, TotalEnergies)

Carbon Capture and Storage (CCS), according to the definition by the IPCC, is a process that captures CO₂ from a point-source.

The terms CCS and Carbon Capture, Utilization, and Storage (CCUS) are closely related and often used interchangeably. Both terms have been used predominantly to refer to Enhanced Oil Recovery (EOR) a process in which captured CO₂ is injected into partially depleted oil reservoirs in order to extract more oil.

Some sources use the term CCS, CCU, or CCUS more broadly, encompassing methods such as Direct Air Capture (DAC) or Direct Air Carbon Capture and Sequestration (DACCS), as well tree-planting which remove CO₂ from the air.

Carbon Dioxide Removal (CDR) is defined by the IPCC as: “Anthropogenic activities removing CO₂ from the atmosphere and durably storing it in geological, terrestrial, or ocean reservoirs, or in products.”

Synonyms for CDR include Greenhouse Gas Removal (GGR), negative emissions technology, and carbon removal. The term geoengineering (or climate engineering) is sometimes used in the scientific literature for CDR. The terms geoengineering or climate engineering are no longer used in IPCC reports.
