This report provides the results from a dedicated analysis of climate policy induced greenhouse gas emission reductions resulting from energy e?ciency improvements. To this end, a model-based approach has been applied using the global energy system model TIAM-ECN for a multiple scenario analysis in which three carbon tax scenarios are assessed against a business as usual scenario. A general ?nding is that there exist energy e?ciency measures, in particular in the en­ergy demand sectors where fuel costs are higher than in the supply sector, which al­low for net cost savings as a result of fuel savings and thus reduced fuel expenditures, even in the absence of carbon tax policy. If climate policy is introduced via car­bon taxes ranging from 40 to 100 $ per tonne of CO2e in 2030, and kept at these levels afterwards, energy e?ciency measures are responsible for 15 to 25 % of the total global greenhouse gas emission reductions until 2050.
