though the Green Workplace Challenge oﬃcially launched on September 14, competitor registration remained open through October 31. By the end of October, 46 organizations had registered for the Green Workplace Challenge. I planned and executed the ﬁrst of the monthly workshops offered to Green Workplace Challenge participants, which focused on how to get started on using the EPA’s Portfolio Manager software to track utility usage and building performance over time. I continued to keep the Green Workplace Challenge website up to date and respond to participants’ questions and concerns, and also facilitated a meeting of the Green Workplace Challenge oversight committee to address several policy questions that had been raised. Lastly, I facilitated a meeting of the Business Climate Coalition, where I brought members up to speed on progress made thus far on the Green Workplace Challenge, and the future direction of the BCC was discussed.
