Mitigation Potential Market Potential: Market Potential: the amount of GHG mitigation that might be expected to occur under forecast market conditions, including policies and measures in place at the time. the amount of GHG mitigation that might be expected to occur under forecast market conditions, including policies and measures in place at the time. Economic Potential: Economic Potential: the potential for cost effective GHG mitigation when non- market social costs and benefits are included with market costs and benefits in assessing the options for particular levels of carbon prices when using social discount rates instead of private ones. the potential for cost effective GHG mitigation when non- market social costs and benefits are included with market costs and benefits in assessing the options for particular levels of carbon prices when using social discount rates instead of private ones.
