Climate change mitigation programs classify two types of carbon offsets: Additional and non-additional. Additional offsets are offsets that correspond to actual reductions in emissions. In contrast, non-additional offsets are offsets that do not correspond to emissions reductions. These offsets...

This paper presents an assessment of the relative efficacy of three key instruments; baselines, trade ratios, and limits; which are under policy discussion in the design of carbon offset programs. Efficiency and distributional considerations are both present in choosing between them. We analyze...

This paper presents an assessment of the relative efficacy of three key instruments – baselines, trade ratios and limits - which are under policy discussion in the design of carbon offset programs. We rank the instruments by their implications for total emissions, economic efficiency, and...
