This week’s question concerns carbon capture technology. With coal estimated to generate at least 25 percent of the world’s carbon dioxide emissions, some scientists are advocating trapping carbon dioxide from coal-fired power plants before they are emitted into the atmosphere, and piping it into secure underground storage facilities. Environmentalists and renewable energy advocates raise a number of objections, including high cost, concerns about carbon dioxide suddenly leaking out from underground sites, and the dubious value of prolonging the life of polluting coal-fired plants.
What do you think? Can carbon capture be a viable means of reducing greenhouse gas emissions? Yes or no?
