This article examines which policy features affect the perceived effectiveness and acceptability of pricing policies aimed to reduce CO-sub-2 emissions. A survey study was conducted among 112 Dutch respondents in 2003. As hypothesized, incentives and policies targeting efficiency behavior were perceived to be more effective and acceptable than were disincentives and policies targeting curtailment behavior. Policies targeting direct energy use were evaluated as more effective than those targeting indirect energy use. No significant differences were found between the acceptability of policies targeting direct and indirect energy savings. As expected, push measures were perceived to be more effective and acceptable when revenues are allocated within the energy domain rather than to general funds. Pull measures were evaluated as more effective when they are funded from within the energy domain rather than from general public funds. The way pull measures are funded did not significantly affect their acceptability.
