| Carbon sequestration is a temporal process in which carbon is continuously being stored/released over time. Different methods of carbon accounting can be used to account for this temporal nature, including annual average carbon, annualized carbon, and ton-year carbon. In this paper, starting by exposing the underlying connections among these methods, we examine how the comparisons of sequestration projects are affected by these methods and the major factors affecting them. We explore the empirical implications for carbon sequestration policies by applying these accounting methods to the Upper Mississippi River Basin, a large and important agriculture area in the United States. We find that the differences are significant in terms of the location of land... |
