About the Workshop

As computing becomes increasingly pervasive—powering everything from large-scale data analytics to AI-driven applications—its energy consumption and carbon footprint continue to grow at an alarming rate. Addressing this challenge requires rigorous, quantitative frameworks that enable the community to measure, model, and reduce carbon emissions at every layer of the computing stack. By developing robust methodologies and well-defined metrics, researchers and practitioners can pinpoint the most impactful interventions, create scalable solutions, and meaningfully track progress toward reducing global emissions.

The Workshop on Measurements, Modeling, and Metrics for Carbon-Aware Computing (CarbonMetrics) offers a focused platform to explore metrics, modeling techniques, and measurement frameworks dedicated to carbon reduction in computing. We encourage contributions that provide scientifically grounded, evidence-based approaches —including novel carbon-aware metrics, predictive modeling methods, and rigorous measurement strategies— that can be deployed and assessed in practice. Our goal is to foster an active community that unites theoretical advances with real-world impact in reducing the carbon intensity of computing systems and services.

CarbonMetrics will be held alongside ACM SIGMETRICS 2025 at Stony Brook in New York.

CarbonMetrics 2025 Workshop is for you if you are:
  1. Carbon Metrics and Measurement Researchers: Investigating frameworks or tools for accurately measuring the carbon footprint of hardware, software, or entire computing ecosystems.
  2. Systems and Resource Management Experts: Focused on scheduling, resource allocation, and performance tuning to optimize carbon efficiency in clouds, HPC clusters, or datacenters.
  3. AI and ML Practitioners: Developing machine learning techniques to predict, analyze, and reduce carbon emissions, or creating carbon-aware data pipelines and training methodologies.
  4. Hardware and Edge Computing Innovators: Designing energy-efficient hardware and exploring carbon-aware approaches for edge deployments and IoT devices.
  5. Lifecycle Assessment Specialists: Applying lifecycle analyses (LCAs) to quantify embodied and operational carbon impacts across the computing stack.
  6. Policy Makers and Sustainability Advocates: Seeking standardized metrics, frameworks, or strategies to drive carbon accountability and policy in the computing industry.

Why Yet Another Sustainable Computing Workshop?

The workshop’s distinct focus is on carbon-aware quantification and decision-making methodologies, spanning areas such as emissions metrics, lifecycle assessments, and data-driven measurement approaches. While HotCarbon addresses a broader set of computer systems topics related to carbon reduction, and SoDec explores social and decision-making dimensions of sustainability, CarbonMetrics offers a narrower, metrics-driven perspective. We seek submissions that offer robust methodologies, clearly defined metrics, and frameworks that can be adopted, compared, and extended by the research community—ensuring direct, measurable impact on carbon reduction in computing.

Overview: The goal for this interactive session is to invite all participants to reflect on the state of the metrics for the 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
