Some climate activists accuse the industry of simply investing in carbon capture as way to extend the use of oil and gas. The technology typically uses chemical absorption to capture carbon dioxide emitted from the chimney of an industrial plant. "The economic viability of carbon capture and sequestration is a challenge today because the cost of building most plants in order to capture carbon dioxide are very significant," the executive said. About two-thirds of the industry's carbon dioxide emissions come from chemical reactions that occur when breaking down limestone. SLB this month announced a nearly $400 million investment in Aker Carbon Capture, a pure-play carbon capture company based in Norway, in an effort to accelerate deployment of the technology at commercial scale.
