This chapter has highlighted significant scientific and technological advances in the area of SCS achieved during the last 15 years. At the project level, the Saskatchewan project demonstrated that increases in SOC as small as 1.2 Mg C ha-1 can be accurately detected in periods as short as 3 years. A number of feasibility or pilot projects are underway worldwide under a variety of environmental and socioeconomic situations. To further advance the field of SCS, more projects like these will be necessary if we are to advance an internationally accepted and adaptable framework that can guide landowner, energy, and government groups in the development of SCS projects. The formation of a collaborative network for these types of SCS projects would be very helpful to compare methodologies in use across diverse environments and to exchange data for laboratory quality controls and verification of simulation models, among other purposes. These activities could go on for 5 to 8 years. These projects would also be useful to advance new methodologies that integrate many of the novel concepts discussed in this chapter as well as many yet to be discovered.
