'''Incentives''' for sustainable action take several forms:
|Personal satisfaction or sense of responsibility|| ||Only a small minority will take serious action. (Many us are well-intentioned but don't get far beyond good intentions.)
|Regulation|| ||Possibility of corruption? Depends on an authority to make decisions - likely to be less creative than a more open approach.
|Taxes||Revenue||Difficulty and controversy involved in setting level of taxes; difficult for authority to raise taxes to the appropriate level due to political and electoral pressure.
|Markets (e.g. carbon trading)||Potential disadvantage: If allocations are given to existing emitters, that effectively rewards polluters.||Strong motivation of personal gain;
efficient allocation of resources.
