Daily Recap: Is the optimal goal 350 ppm or 550 ppm?
Tuesday, June 24th, 2008This past semester, I studied the price of oil and its relationship to the cost of climate mitigation. It culminated in a paper for Professor Michael Oppenheimer that showed sustained record prices for oil will help make deep emission cuts much cheaper than before. The current price acts not only as a large tax on oil, to the tune of $200 per ton of carbon dioxide, but also pulls the price of other fossil energy sources up as well (as we have been reporting for natural gas and coal). Such a price level was unfathomable in previous mitigation cost models such as the Stern Review estimate of a high oil price being $80 per barrel (70% below today). If oil prices rise to $250 per barrel next year as Gazprom projected that would be equivalent to an almost $500 per ton of carbon dioxide without policymakers having to intervene. The current higher prices, as modeled in the Stern Review, would move optimal concentration of greenhouse gases down a great deal from the 550 parts per million (ppm) level originally estimated by the 2006 study.
