Introduction 

With policymakers pursuing climate objectives through ambitious emission mitigation targets, such as President Joe Biden’s new nationally determined contribution under the Paris Agreement (50-52 percent reduction by 2030), there are questions regarding the feasibility of reaching those targets—especially in difficult to abate sectors. Consequently, carbon offsets have increasingly emerged as an opportunity to “offset” emissions that are otherwise uneconomical to abate, which allows for private sector investment to produce equal or better climate benefit via low-cost opportunities from offsets relative to the higher-cost abatement opportunities.

However, there is considerable skepticism around the feasibility of offsets to produce reasonable climate benefits that are substitutable with other emission mitigation measures. Carbon offsets may not always provide additional climate benefit or offer permanent storage of carbon. Nevertheless, this paper explores some of the existing literature on estimating the potential for carbon offset growth and its economic utility.

While the potential for carbon offsets seems uncertain, their potential is considerable. Efficient allocation of carbon offsets is more economically efficient than alternative, command-and-control emission mitigation measures. The cost of a carbon offset can be under $10, while emission abatement opportunities can exceed hundreds or even thousands of dollars per ton. Furthermore, offsets also deliver a global incentive for private sector investment in emission mitigation. Despite the difficulties, carbon offsets offer a fruitful opportunity for improving greenhouse gas emission concentrations beyond solely relying on emission mitigation.
