As a result,
without effective mitigation, total energy - related carbon dioxide emissions (including transformations, own use and losses) will rise from 26.1 GtCO2 (7.2 GtC) in 2004 to around 37 — 40 GtCO2 (11.1 GtC) in 2030 (IEA, 2006b; Price and de la Rue du Can, 2006), possibly even higher (Fisher, 2006), assuming modest energy - efficiency improvements are made to technologies currently in use.
► Economic potential is in most studies used as the amount of heat - trapping gas (greenhouse gas)
mitigation that is cost -
effective for a given carbon price, based on social cost pricing and discount rates, including energy savings, but
without most externalities.
