The title of Chief Project Officer (CPO) is just a job title for one person. Whether there's a CPO or not depends on what the organization needs. However, the Project Management Office (PMO) plays a vital role in making projects innovative and bringing about changes. So, instead of focusing on having more CPOs, it might be better to promote the PMO first. Maybe later, when organizations realize they need it, we'll see more CPOs.
Below is one of the PMI webinar that are interesting to watch:
