What are the local health, safety and environmental risks of CCS?
On local risks associated with carbon dioxide pipeline transport, ZAMBIA sought clarification of a statement that the risks are possibly lower than comparable hydrocarbon pipelines. Lead Author Richard Doctor explained that the statement was based on 20 years of experience in the US. The text was accepted without amendment. Lead Authors Richard Doctor and Peter Cook answered questions on the risks to humans of exposure to concentrations of carbon dioxide. The US proposed, and delegates agreed, to specify that a sudden, large release of carbon dioxide would pose immediate dangers to human life and health at exposures to concentrations of carbon dioxide greater than 7-10% by volume in air. Delegates agreed to a US proposal to add a sentence from the Technical Summary noting that no major obstacles to pipeline design for CCS are foreseen. On the risks posed by geological storage, Co-Chair Davidson introduced text that notes that with appropriate site selection, a regulatory system, and th
