|Bottom line | Since offset usage is a function of actual emissions, which is distinct from an emissions cap, usage is independent of the stringency of the cap.|
One of the key features of placing a carbon cap is how stringent it should be, in terms of the volume of emissions reductions and the timeline for achieving that volume of reductions. Indeed, stringency is one of the primary factors considered by California when assessing whether to link its cap and trade program. Offsets are a function of a cap and trade program, and questions around the extent to which they can be used are often cited as evidence of the stringency of the program. The implication is that the higher the offset usage limit the less stringent the cap.
This inference misses the mark. Offsets within a cap and trade program have their usage limits set as a percentage of actual emissions, which are independent of the cap.
California’s greenhouse gas emissions declined by 4.8% in 2016, which was steeper than the 3.1% decline in the cap. The independence of these figures demonstrates that debates about reducing offset usage to increase the stringency of the cap are off-base. When actual emissions are below the cap as they were in 2016, the offset ceiling of 8% of emissions is equivalent to an offset ceiling of 7% of the cap in 2016.
