The SPMS provides goals and targets, yet should also be driving a cycle of feedback and adaptive management. Using information from indicators, the SPMS should provide a means toward efficient, effective, and meaningful reporting.

National reporting cycles, such as by Parties to Convention COPs, provide one means by which progress against the SPMS can be measured. These reports should help build a picture of progress toward achievement of the goals and targets of the SPMS, and highlight areas for attention. Continued development of harmonized on-line reporting systems is expected to be important in this regard.

Under this functional heading the Companion Volume will aim to include the elements of the CMS national reporting process directly relevant to each of the 16 SPMS targets. In addition, it will also include relevant elements of possible other reporting and progress review processes established within CMS and CMS instruments.
