Environmental sustainability is finally taking center stage among the priorities for technology. There is growing awareness of climate change, increased emphasis on corporate responsibility, and increasing costs for not addressing these. Ultimately, the goal is Net Zero. Cloud providers and users can start tackling this with power consumption accountability, energy efficiency, GreenOps, and cost optimization techniques. Initiatives exist to monitor and address these issues, such as the Software Carbon Intensity specification, but the data is still evolving. This panel has representatives from the Green Software Foundation, CNCF Environmental Sustainability TAG, and O-RAN. We will discuss areas applicable to our representative organizations, corresponding solutions, and how these complement each other. We will discuss the specifics of workloads such as Telco, HPC, AI/ML, and generic IT workloads, and the challenges around these.
