LONDON, England — Lord Oxburgh, chairman of Shell Transport and Trading Co. (the oil company’s British division) said carbon dioxide emissions must be cut or else he has "little hope for the world."

“No one can be comfortable at the prospect of continuing to pump out the amounts of carbon dioxide that we are at present,” Oxburgh told the Guardian newspaper. “People are going to go on allowing this atmospheric carbon dioxide to build up, with consequences that we really can’t predict, but are probably not good.”

Oxburgh told the newspaper the solution may be in sequestration, or capturing CO2 gas so it can be stored rather than emitting it into the air. It’s an expensive technique, however.

“Sequestration is difficult,” Oxburgh acknowledged. “But if we don’t have sequestration I see very little hope for the world.”
