Hello CarbonMetrics 2025 attendees, welcome to the technical program for the workshop!

We are excited to welcome you to CarbonMetrics 2025—a focused workshop on metrics, modeling, and measurement strategies for carbon-aware computing. Our program features insightful talks from researchers advancing rigorous, practical approaches to reducing carbon emissions across the computing stack. We thank all speakers for contributing their work and joining us in shaping this community.

Logistics: Each talk is allocated 20 minutes, typically split into 15 minutes of presentation followed by 5 minutes of Q&A. All times are in Eastern Time (ET, GMT-5). Remote participants are welcome to join us via Zoom at the link below.

01:30pm - 03:00pm: Breakout Discussion on Where Are We and Where Do We Want to Go?

Overview: The goal for this interactive session is to invite all participants to reflect on the state of the metrics for carbon-aware computing field. We will divide the attendees into groups of 4–6 attendees each. Attendees will explore what's working, what's not, and what they hope CarbonMetrics—and the broader community—will look like one year from now.

Format:

• Parallel groups of 4-6 attendees, each with a facilitator and notetaker
• All groups will explore the same set of guiding questions (see below)
• Each group reports back in the final 20–25 minutes

Guiding Questions:

1. Where do we think the field currently stands?
   How mature or fragmented is it? Is there a shared understanding of what carbon-aware computing even means?
2. What do we appreciate about current efforts?
   Which trends, papers, tools, collaborations, or community norms are encouraging?
3. What frustrates us or feels misaligned?
   What are the main barriers—technical, institutional, cultural—that are holding the field back?
4. What do we want this space to look like one year from now?
   What kinds of submissions, collaborations, and values should CarbonMetrics 2026 support?

Suggested Agenda:

• 1:30–1:40pm: Introduction and orientation
• 1:40–2:40pm: Breakout group discussions
• 2:40–3:00pm: Report-back and synthesis

Group Output:

• Each group will summarize key ideas in a 3–5 minute verbal report
• Google Drive Folder with Google Docs for notetaking: Link.
